Front left ABS wheel speed sensor replacement may be needed when a Japan-built 2003–2007 Honda Accord 2.4L sedan or a 2004–2008 Acura TSX 2.4L develops an ABS warning, intermittent wheel-speed readings, or unwanted low-speed ABS operation. Honda/Acura service information for this generation identifies DTC 13 with a left-front wheel-sensor circuit open or short; read the complete description in the vehicle’s ABS/VSA module. A warning light or code alone does not prove the sensor has failed.
Application overview
This guide covers the front-left corner of left-hand-drive, front-wheel-drive 2.4L gasoline sedans. Left means the vehicle’s left when seated facing forward. The Accord must be built in Japan; the model name and year alone are not enough. Check the VIN, manufacturing label, and a VIN-based parts catalog before ordering.
The procedure is limited to ordinary sensor and attached-lead replacement. It does not cover Accord coupes, other assembly-country versions, V6 or hybrid service, the 2008 Accord, or the 2009-and-newer TSX. Those exclusions define this guide’s repair scope, rather than a claim about every application of the underlying OEM part number.
Featured replacement sensor
A-Premium front-left ABS wheel speed sensor, manufacturer part ABS0040, ASIN B01IA35JX6, is sold as one sensor for the driver-side front position. The assembly has an attached lead and connector. It is not a pair, a rear sensor, a wheel bearing, or an ABS control unit. Do not assume replacement bolts or every body clip are included.
The manufacturer cross-references 57455-SDC-013; Honda’s catalog supersedes that number to 57455-SDH-003. Use the VIN-specific catalog result and compare the connector keying, mounting ear, lead length, grommets, and bracket locations with the original. A matching connector alone does not establish correct fitment.

Vehicle compatibility
| Make / model | Model years | Engine / drive | Body and selection restrictions |
|---|---|---|---|
| Honda Accord | 2003–2007 | 2.4L gasoline inline-four; FWD | Japan-built sedan only within this guide; front left; verify VIN and original connector/routing. |
| Acura TSX | 2004–2008 | 2.4L gasoline inline-four; FWD | Sedan; front left; verify VIN, connector, and lead supports. |
The cited sensor listings do not distinguish manual from automatic transmission within these applications. Confirm the exact vehicle in the catalog rather than assuming a transmission match removes the Accord assembly-location restriction. Keep the old part available until the new assembly has been compared and fitted.
Diagnose before replacing the sensor
Use a scanner with Honda/Acura ABS or VSA access, not just generic engine-code reading. Save the module identification, full fault text, and available data before clearing anything. Code 13 is a brake-system diagnostic identifier here, not engine code P0013. The circuit, connector, sensor, and control unit must be considered separately.
- Confirm the corner. Compare the four wheel-speed channels using the scanner’s supported test procedure. A left-front reading that drops out while the others agree directs the investigation; it does not identify the failed piece by itself.
- Inspect the complete lead. Look for tire contact, stretched wiring, cracked insulation, missing supports, corrosion, or water at the connector. Pay attention to recent suspension, brake, and bearing work.
- Check mechanical causes. Bearing play, a damaged magnetic encoder, debris, incorrect bearing installation, or mismatched tires can produce implausible wheel-speed information. A new sensor cannot repair those problems.
- Follow the correct electrical test plan. Use the wiring diagram for the actual ABS/VSA system. Do not apply battery voltage to the sensor or use a universal passive-sensor resistance threshold. If circuit testing is outside your experience, pay for diagnosis before purchasing parts.
The 2004 TSX service manual also describes electrical-noise/intermittent-interruption and magnetic-encoder faults. These require their own inspection paths. Avoid replacing all four sensors merely because several warning lamps illuminate together.
Tools, parts, and supplies
The demonstrated Accord fasteners use a 10 mm socket, with a 19 mm socket for standard wheel nuts. Confirm the actual hardware, especially aftermarket wheels or locking nuts. The small socket kit and sensor torque wrench are 1/4-inch drive; the wheel tools are 1/2-inch drive. No drive adapter is needed for these combinations.

| Typical replacement total | $25–$75, excluding tools and diagnosis | $150–$350 before separate diagnosis or extraction work. |
Step-by-step replacement overview
1. Record the fault and compare the new part
Identify the front-left circuit through diagnosis. With the ignition off, compare the replacement to the installed assembly and photograph every support point. Confirm a sound mounting ear, matching connector, and enough lead length to follow the original route without stretching. Do not cut or splice the new lead to make an incorrect part fit.
2. Lift and support the front safely
On level pavement, set the parking brake and transmission, chock both rear wheels, and loosen the left-front wheel nuts slightly. Identify the factory front jacking bracket and reinforced side support points behind the front wheels using the vehicle’s lift-point illustration. Center the jack saddle on the bracket, raise the front, position the two stands at the designated side points, engage their locks, and lower the vehicle onto them. Confirm stable contact before removing the wheel.
Do not jack under the oil pan, steering rack, thin floor, or an unverified suspension member. If corrosion or saddle shape prevents secure support, stop. Keep the engine off throughout the work.
3. Release the lead and connector
Trace the sensor wire upward from the knuckle. On the Accord arrangement, the lead is retained along the knuckle and upper-arm area and passes through the body opening to its engine-compartment connector. Release the connector latch and separate the housings without pulling on the wires. Remove the accessible 10 mm-head retention fasteners and release the body clips. On the TSX, follow its existing supports and connector position; do not copy clip placement from a different vehicle.
4. Remove the sensor without damaging the bearing
Remove the small sensor mounting bolt with a fully seated six-point socket. Gently work the sensor out by its body while protecting the lead. Keep dirt out of the opening and avoid contacting the encoder. If the sensor will not release with controlled hand movement, stop; a rust-bound sensor may break and require knuckle removal. That larger procedure involves additional fasteners and specifications and is outside this guide.
5. Inspect the seat and install
Remove loose dirt from around the seat with a clean cloth. Inspect for a broken sensor tip, cracked mounting ear, damaged bore, and wiring damage. The replacement must sit fully and squarely against its mounting surface without being drawn in by the bolt. Do not add washers to change the air gap or apply general-purpose anti-seize to the sensing end. If corrosion prevents seating, have the mounting area repaired before continuing.
Install the sensor gently without twisting its lead. Start the original correct fastener by hand, then tighten the factory 6 mm sensor mounting bolt to 9.8 Nm (7.2 ft-lb; approximately 87 in-lb). “6 mm” describes the thread diameter, not the socket size. Keep torque-wrench access straight.
| Fastener / application | Specification | Use and limitation |
|---|---|---|
| Factory front wheel-sensor 6 mm mounting bolt — covered Accord and TSX | 9.8 Nm / 7.2 ft-lb / approximately 87 in-lb | Honda ABS/VSA replacement illustration and Acura TSX service illustration; do not apply this to suspension fasteners. |
| Factory wheel nuts — covered Accord and TSX | 108 Nm / 80 ft-lb | Tighten in a crisscross pattern with clean, unlubricated threads and seats. |
6. Restore the routing and retention
Refit the lead to every original bracket, clip, and body opening, keeping its molded locating points aligned. Refit the original small retention fasteners; use the specification shown for their exact locations in the vehicle’s service illustration. Do not treat a 10 mm socket size as a torque specification. Fully latch the connector and make sure any body seal is seated.
Check clearance through steering movement before fitting the wheel. The wire must not pull tight, rub the tire or rotor, contact the axle, or become trapped under a bracket. Replace broken clips with the correct parts. A loose harness can quickly damage an otherwise good new sensor.
7. Refit the wheel and verify the repair
Refit the wheel and hand-start all nuts. Snug them evenly, raise the car enough to remove the stands, then lower until the tire cannot turn. Tighten the factory nuts in a crisscross sequence to 108 Nm (80 ft-lb), and finish lowering. Remove the jack and chocks only when the vehicle is securely parked.
Clear the recorded ABS/VSA faults with the correct scan function, cycle the ignition, and check normal brake-pedal feel before moving. Follow the module’s prescribed confirmation drive on a safe route. The TSX service test includes travel above 19 mph (30 km/h); attempt that only after the car passes the stationary checks. Disconnect the diagnostic tool when the factory test calls for it, and never watch a screen while driving. Rescan afterward. A returning fault or abnormal braking requires diagnosis, not repeated code clearing.
Common mistakes
- Ordering by model year alone and overlooking Japan-built Accord fitment or the left-front position.
- Assuming an ABS lamp proves sensor failure while ignoring wiring, connectors, tires, or the bearing encoder.
- Confusing inch-pounds with foot-pounds on the small mounting bolt.
- Using the retaining bolt to force a sensor into a rusty bore, or drilling toward the encoder.
- Leaving out cable supports, routing the wire across a moving part, or lubricating wheel-nut threads.
- Skipping the post-repair scan because the warning lamp briefly went out.
Frequently asked questions
Can I replace only the left-front sensor?
Yes, when diagnosis identifies that sensor as the failed component. The featured listing supplies one sensor. The other corners do not automatically need replacement.
Will an inexpensive engine-code reader work?
Only if it also supports the vehicle’s ABS/VSA module. Generic emissions-code access alone is insufficient for this diagnosis.
Does this require brake bleeding?
Ordinary sensor replacement does not open the hydraulic circuit. If a seized sensor leads to more extensive work, reassess the procedure and all required specifications before proceeding.
Does the new sensor need coding?
The replacement sensor is not an ABS/VSA control module. Routine sensor replacement calls for fault clearing and confirmation checks. Do not perform steering-angle or VSA neutral-position procedures merely because a wheel sensor was replaced; follow any separate diagnostic requirement.
What if the warning returns immediately?
Recheck the correct part, full connector engagement, harness routing, sensor seating, circuit condition, and encoder/bearing. Preserve the new fault information and continue diagnosis.
Can I keep driving with the ABS light on?
Do not rely on ABS or stability assistance while a fault is active. A red brake warning, abnormal pedal, fluid leak, or unexpected braking means stop driving and arrange assessment or recovery.
