Fuel pump replacement on a 2003 Honda CR-V 2.4L 4WD begins with checking hard starting, a crank/no-start condition, stalling or loss of power. P0171 means the fuel system is too lean, but a lean code or pump noise alone does not prove the pump is faulty. This guide covers the gasoline model and its rear floor access-panel service method.
Intermediate to advanced DIY: pressurized fuel and careful sealing
Allow 1.5–3 hours after diagnosis with accessible, undamaged hardware; estimate
Approximately $175–$320 for a module and routine replacement materials; estimate, before tools
Work with a cool vehicle in a well-ventilated area, away from smoking, flames, hot lamps and equipment that can ignite fuel vapor. Wear splash goggles and fuel-compatible gloves. Follow the pressure-release sequence before opening the system, protect the interior, and contain residual fuel. Stop for a damaged tank opening, leaking fuel line, mismatched connector or an inability to obtain the required new sealing parts.
Featured fuel-pump and sender module
A-Premium electric fuel-pump module — ASIN B07GBC6NQK is the supplied product. Amazon identifies the manufacturer part number as APFP0197AM; the corresponding A-Premium catalog uses APFP0197. The product includes one electric pump assembly with a fuel-level sender, float and inlet strainer. The catalog specifies a four-pin version and does not include a pressure sensor or external replacement wiring harness.
Obtain the correct new base seal before starting. The manufacturer lists the gasket as not included. Check the delivered package, the installed module and the service-parts requirements below; do not assume every loose seal, retainer or washer is supplied.

Catalog comparison references include 17045-S9A-A00, E8733M, P76394M, FG0963, SP8024M, SP8037M and 67906. Use the APFP0197 application catalog together with the vehicle configuration and the original module. A shared interchange number does not override a connector or plumbing mismatch.
Compatibility and configuration checks
The manufacturer lists these CR-V applications with the 2.4L gasoline four-cylinder engine. Keep the 2004 build-location restriction separate. The detailed procedure below is for the 2003 4WD vehicle; broader catalog fitment does not make the pressure-release procedures for other years interchangeable.
| Make and model | Years | Engine | Configuration requirement |
|---|---|---|---|
| Honda CR-V | 2002–2003 | 2.4L gasoline inline-four | Match the four-pin module and all fuel/vapor connections. Detailed service example: 2003 4WD. |
| Honda CR-V | 2004 | 2.4L gasoline inline-four | Japan-built vehicle only; confirm build location and installed module. |
| Honda CR-V | 2005–2006 | 2.4L gasoline inline-four | Manufacturer-listed product application; use the correct year-specific service procedure. |
Before ordering, compare the connector housing and keying, populated terminals, tube fittings, flange, module height and float travel. Read the vehicle identification/build label and account for any previously replaced tank or module. Never force a plug, block an unexplained connection, or splice wires to make a different version fit.
Compare occupied contacts, not just the connector label. Honda calls the housing a 5P connector, while its connector drawing shows four used terminal positions and one blank position. The featured module is sold as the four-pin version. Check the actual housing, keying and metal contacts before installation. The selected listing’s “with 2 tube” style also requires a direct comparison of the original plumbing; a visible tube fitting alone does not establish an additional active hose connection.

Diagnose the fault before buying a pump
| Symptom or finding | Check first | Why it matters |
|---|---|---|
| Cranks but does not start | Actual fuel level, battery/cranking condition, ignition and fuel-pump electrical supply | A pump cannot run correctly without its power and ground; other systems can also prevent starting. |
| Weak acceleration or stalling | Measured fuel pressure, fuel quality and supply restrictions | A restricted filter, poor connection or pressure-regulation fault can resemble a weak pump. |
| P0171 or unstable idle | Complete lean-condition diagnosis, including intake leaks and sensor inputs | The code reports mixture control, not a confirmed failed fuel pump. |
| Incorrect fuel-gauge reading | Sender circuit, connector and free float movement | The level sender measures fuel; it does not establish the pump’s delivery pressure. |
| Fuel smell after service | Base seal, damper washers and every disturbed fuel connection | Shut down and repair any leakage before driving. |
Save codes and freeze-frame information before disconnecting the battery. Listening for the short pump prime is a useful first observation, but a running motor still needs adequate pressure and delivery. Complete electrical checks before opening fuel connections whenever possible.
P0171 means “Fuel System Too Lean.” Honda’s 2003 diagnostic procedure checks fuel trims and pressure, then considers the fuel feed line, pump, filter/regulator, purge valve and injectors. Relevant MAP, A/F-sensor and oxygen-sensor faults take priority when present. The code alone does not establish a failed pump. P0171 diagnosis.
The factory pressure test uses a gauge attachment 07VAJ-0040100 in place of the fuel pulsation damper, with the corresponding Honda pressure gauge/set or a verified equivalent. It is not a generic Schrader-port connection. Relieve pressure as described below, fit and secure the correct test equipment, restore battery power and check for leaks before running. At idle, pressure should be 330–380 kPa (48–55 psi). If the engine will not start, confirm the pump’s two-second key-on operation; if it is silent, follow the pump-circuit checks before condemning the module. 2003 pressure test; pump-circuit diagnosis.
Keep test hoses away from heat and moving parts. Afterward, switch off, relieve trapped test pressure using the equipment’s controlled bleed into an approved gasoline container, isolate battery negative and remove the gauge. Refit the damper with a new sealing washer at 22 N·m (16 lb-ft), then repeat the leak check. Use professional testing if the correct adapter and safe pressure-release equipment are unavailable.
Tools, replacement parts and supplies
Have the correct sender wrench and new sealing parts available before relieving pressure. The factory access panel allows this module repair without removing the tank. Use equipment matched to the fuel connection and the actual fasteners, and keep fuel-contaminated materials out of the cabin.

2003 Honda CR-V 2.4L 4WD replacement procedure
The detailed example is a 2003 Honda CR-V 2.4L 4WD, using the factory opening beneath the rear seats. Park on firm, level ground, apply the parking brake and work with a cool engine and good ventilation. Keep ignition sources away and protect the upholstery. Prepare a stable gasoline-approved catch receiver sized for the withdrawn module and float, together with its matching closable collection vessel; use absorbent pads for stray drips.
1. Record diagnostic information and prepare the replacement
Save codes, freeze-frame and relevant live data before disconnecting power. Have the radio anti-theft code and record its presets. Compare the replacement’s mounting flange, connector shell and terminal positions, outlet connection and float travel with the original. Obtain a new module base gasket, new fuel-line retainer and correct new pulsation-damper sealing washer. Inspect the original retaining nut for cracked tabs or damaged threads. Module service; retainer replacement rules.
2. Relieve pressure at the fuel pulsation damper
Switch the ignition off and disconnect battery negative. Remove the fuel cap and engine cover. Fit the wrench to the pulsation damper on the fuel rail, cover the area with a shop towel and slowly loosen the damper one complete turn, capturing escaping fuel. Keep your face away from the connection. This is the 2003 factory relief method. Pressure relief.
Once pressure has dissipated, remove the damper to renew its sealing washer; every disturbed damper sealing washer must be replaced. Reinstall and tighten to 22 N·m (16 lb-ft). Leave the battery disconnected while servicing the tank unit. Refit the engine cover after confirming the damper is dry during the final leak check. Damper reassembly specification.
3. Open the rear floor access panel
Fold the rear seats forward and pull the carpet back to expose the service panel. Remove its fasteners and lift it carefully around the wiring. Clean dirt from the module top before opening the tank. Unplug the module connector by releasing its latch; pull the connector housing, not its wires.
Clean the fuel quick-connect. Hold its body, squeeze both retainer tabs with your fingers and pull it off the module fitting. If it resists, keep the tabs pressed while gently pushing and pulling. Inspect the connector and sealing surface for damage, and cover the disconnected line with a clean plastic bag. The factory specifies hand release, without a prying or disconnect tool. Fuel-line disconnection.
4. Remove the retaining nut and complete module
Use Honda sender wrench 07XAA-001010A, or its verified superseding 07AAA-S0XA100, to loosen the threaded retaining nut. Lift out the nut and module carefully, tilting only as needed to clear the float without bending its arm. Catch residual fuel and keep debris outside the tank.
Remove the old base gasket and clean the sealing surfaces. Keep a complete replacement assembly assembled; verify that its strainer, sender and internal connectors are secure. Internal O-ring replacement becomes relevant only if those internal joints are opened. Factory module and alignment diagrams.
5. Seat the new seal and index the module
Fit the new base gasket evenly at the tank/module sealing joint and lower the module carefully. Align the factory marks on the tank and module before starting the retaining nut by hand. Keep the gasket seated without twisting or pinching and confirm the float moves freely. Tighten the nut with the sender wrench to 93 N·m (69 lb-ft), as shown in the factory tool diagram. Recheck alignment and the visible gasket edge. Locknut torque and indexing.
6. Fit the new retainer and reconnect
Install the correct new retainer in the fuel-line connector; do not transfer the old retainer from the removed module. Align the connector grooves with both retainer pawls, then push it onto the clean fitting until both pawls click into place. If difficult to connect, Honda permits a small amount of new engine oil on the line end. Confirm both locks visually and tug the connector. Reconnect the electrical plug and check its latch. Quick-connect installation.
7. Prime, inspect and restore the interior
Install the fuel cap, reconnect battery negative and turn the ignition to ON (II) without cranking. The pump runs about two seconds. Switch off and repeat two or three times, checking the module seal, quick-connect and underhood damper for leakage. Shut off and correct any wetness before starting. After a dry pressure check, refit the access panel, carpet and seats, securing the seat latches. Factory priming and leak check.
8. Complete the Honda idle relearn
Battery disconnection requires an idle relearn on this model. Complete any pressure testing before the final battery reconnection and relearn. Turn all electrical loads off. Start in Park or neutral and hold 3,000 rpm without load until the radiator fan operates or coolant reaches 90°C (194°F). Then let it idle with the throttle closed for about five minutes, excluding time the radiator fan runs. Restore the radio code, presets and clock. Confirm the fuel gauge, starting and stable idle, then rescan for returning faults. 2003 idle-learn procedure.
Common mistakes to avoid
- Ordering by the broad 2002–2006 year range without checking the 2004 Japan-build restriction or module connections.
- Opening the system before releasing pressure, or reusing sealing washers that the procedure requires replacing.
- Damaging the plastic retaining hardware with an unsuitable tool.
- Twisting the sender arm, trapping a seal or misaligning the module at the tank marks.
- Leaving a quick-connect fitting partly latched or closing the access panel before checking for leaks.
- Replacing the pump solely because a lean code is present.
Frequently asked questions
Does this fit every 2004 CR-V?
No. The product catalog restricts the 2004 application to Japan-built vehicles. Verify the build location and the exact module configuration before ordering.
Does the tank have to come out?
The scoped 2003 factory procedure uses the rear floor access panel after the seats are folded and the carpet moved. It does not require cutting a new opening or removing the tank.
Can I reuse the old base seal?
Install the specified new base seal and any other new sealing parts required by the service procedure. A flattened or damaged seal can leak even when the new pump runs correctly.
Will a new pump fix an inaccurate fuel gauge?
The assembly includes a sender, but the fault may be in the connector, wiring or gauge system. Check that circuit and confirm the float can move freely before assuming the complete assembly is the cause.
What if the new connector or tube fittings differ?
Stop and resolve the application. Compare the actual housing, terminal arrangement and plumbing with the original module. This guide does not authorize wiring conversions or plugging unused connections.
