For a 2008 Honda Accord, replacing the camshaft position sensor typically costs around $150 to $350, depending on the engine variant, labor rates, and whether any related components need service.
Cost overview
The price you pay reflects the parts price, how long the job takes, and any diagnostic fees. Here are the main cost drivers:
- Parts price: The camshaft position sensor itself is typically $40 to $120 for aftermarket parts, and $80 to $160 or more for genuine Honda OEM parts.
- Labor time: Replacement usually requires 0.5 to 2 hours, depending on engine type and how accessible the sensor is. Labor rates vary by shop and region, commonly $75 to $150 per hour.
- Diagnostic fees: Some shops charge a diagnostic fee if you’re not returning for the repair; many waive this if you proceed with the repair.
- Additional repairs: If the sensor failure has caused related issues, or if access requires removing components like the air intake or timing cover, the bill can rise.
In practice, a typical total in most U.S. regions falls roughly in the $150 to $350 range, but can be higher when OEM parts are used or if the engine requires more extensive labor.
Engine variant considerations
The 2008 Accord was offered with different engines (a 2.4-liter inline-four and a 3.0-liter V6). Access to the camshaft position sensor and the complexity of the replacement varies by engine, affecting both parts price and labor time.
2.4L inline-four (2.4L I4)
More common in the 2008 Accord, this engine typically has the CMP sensor in a location that is easier to reach, translating to shorter labor times and slightly lower costs.
3.0L V6
The 3.0-liter V6 variant can place the sensor behind more components and may require removal of accessories for access, which can increase labor time and total cost.
DIY considerations
Replacing a camshaft position sensor is a moderately easy task for someone with basic automotive skills, but it involves disconnecting electrical connectors and working around the engine. If you’re not comfortable, a professional replacement is recommended to avoid misdiagnosis or timing-related issues.
If you choose to do it yourself, ensure you have the correct sensor, disconnect the battery, use proper torque specs, and clear any fault codes after installation with an OBD-II scanner.
What to ask your shop
To get an accurate quote, ask about:
- Whether the quote includes parts (sensor vs. OEM vs. aftermarket) and labor only.
- Labor rate per hour and estimated time to complete the job.
- Whether diagnostic fees apply and if they are waived if you proceed with the repair.
- Any additional costs for related components or timing-related work.
Understanding these factors will help you compare estimates and avoid surprises at checkout.
Summary
Replacing the camshaft position sensor on a 2008 Honda Accord typically falls in the $150–$350 range, with variations based on engine variant (2.4L I4 versus 3.0L V6), parts choice (OEM vs aftermarket), and local labor rates. If you notice engine trouble codes like P0340, poor fuel economy, or misfires, addressing the CMP sensor promptly can prevent further issues. Always verify what’s included in the quote and whether any ancillary services are required.
