Replacing a camshaft position sensor (CPS) on a Honda Civic typically runs about $150 to $350 in total, depending on the model year, engine type, and regional labor rates. Parts generally run from roughly $20 to $180, while labor often accounts for the larger portion of the bill. DIY buyers can trim costs by supplying the sensor and performing the work themselves.
What a camshaft position sensor does
The camshaft position sensor monitors the position and rotational speed of the camshaft, sending data to the engine control unit to help time ignition and fuel injection. A faulty sensor can trigger misfires, rough idling, poor fuel economy, or a check-engine light with codes such as P0340 or P0341, depending on the Civic’s year and engine. Replacing the sensor is a common, straightforward repair for those experiencing those symptoms.
Cost breakdown
Below is a typical price breakdown you can expect when replacing a CPS on a Honda Civic, covering parts, labor, and common extras.
- Parts: Camshaft position sensor price varies by brand and OEM status. Aftermarket CPS parts commonly run about $20–$100, while genuine Honda (OEM) sensors typically cost $60–$180.
- Labor: Most Civic CPS replacements require about 1–2 hours of shop time. Local rates commonly range from roughly $75–$125 per hour, though some high-cost areas charge more. Total labor can be about $75–$250.
- Diagnostics and shop fees: Some shops include the diagnostic check in the labor, others charge a separate diagnostic or inspection fee, typically $0–$60.
- Possible add-ons: If the sensor is difficult to access or requires removing timing belt/chain covers, additional labor or parts may be needed, potentially adding $100–$300 or more in uncommon cases.
Prices vary by region, dealership vs. independent shop, and the Civic’s specific engine type. The figures above reflect common ranges in the United States and may differ elsewhere.
Factors that influence price
Several factors can push the total cost higher or lower. Here is what matters most when budgeting for a CPS replacement on a Honda Civic.
- Engine type and model year: Different Civic generations (for example, those with different K-series or D-series engines) place the CPS in different locations and with varying accessibility, which affects labor time.
- Location and labor rates: Urban areas and high-cost regions tend to have higher hourly rates than rural areas.
- Shop vs. dealership: Dealers tend to charge more for labor and parts than independent repair shops, though warranties can differ.
- DIY vs. professional installation: Doing it yourself eliminates labor charges but requires tools and skills; mistakes can lead to more costly issues later.
- Additional repairs: If the timing belt/chain, tensioner, or water pump are involved or due for service, prices rise due to extra parts and labor.
The total you pay will hinge on these variables, so it’s wise to request a written estimate that separates parts, labor, and any potential add-ons before authorizing the work.
DIY considerations and tips
If you choose to replace the CPS yourself, ensure you have the proper replacement sensor for your Civic’s engine code and year. Common steps include locating the sensor near the camshaft gear, disconnecting the electrical connector, removing the mounting bolt, swapping in the new sensor, and torquing the bolt to specification. After installation, clear any fault codes and test-drive the vehicle to confirm the issue is resolved. Keep in mind that improper installation can cause timing issues or electrical damage, so proceed only if you’re confident in your mechanic skills.
Summary
For most Honda Civic owners, replacing the camshaft position sensor costs about $150–$350 when performed by a shop, with sensor parts generally in the $20–$180 range and labor in the $75–$250 range depending on location and engine. DIY replacements can reduce costs further to roughly the sensor price alone. Always obtain a detailed estimate that separates parts, labor, diagnostics, and any anticipated extra work, especially if timing components may need service.
