Typically, replacing a camshaft position sensor on a 2004 Honda Civic costs about 70 to 300 dollars, depending on parts choice and labor rates.
The camshaft position sensor (CMP) helps the engine control module manage ignition timing and fuel injection by monitoring the camshaft’s position. If the sensor fails, drivers may see a check engine light, stalling, rough idle, or misfires. On a 2004 Civic, the CMP sensor is usually located near the engine head or timing area, and access may require removing a portion of the timing belt cover. Costs vary by region, whether you choose an aftermarket part, and whether a diagnostic fee is charged by the shop.
Cost breakdown
Here is a typical breakdown of the main cost components you’re likely to encounter for this replacement.
- Parts cost (sensor itself): Aftermarket CMP/CKP sensors typically range from $20 to $60; Honda OEM sensors commonly run from about $60 to $120.
- Additional parts (if needed): Gaskets, seals, or minor hardware in the vicinity of the timing area, usually around $5 to $20.
Overall, parts for a CMP/CKP sensor replacement usually run from about $25 to $140, depending on whether you choose aftermarket or OEM parts and the engine variant.
Labor costs and time
The labor cost depends on how long the job takes and the local shop rate. Below is a typical range you might see.
- Estimated labor time: 0.5 to 1.5 hours, depending on accessibility and whether any timing cover work is required.
- Labor rate: Independent shops commonly charge about $75 to $125 per hour; dealerships can be $100 to $150+ per hour.
- Estimated labor cost: Approximately $40 to $190 at an independent shop; about $100 to $225 at a dealership.
Most customers can expect total labor costs to fall roughly in the $40 to $225 range, with totals rising if dealership pricing or additional related work is involved.
Additional costs and considerations
Beyond the sensor and labor, consider these potential charges or needs that can affect the final price.
- Diagnostic fee: Some shops waive this if you proceed with the repair; others charge a separate fee, typically $0 to $100.
- Taxes and shop supplies: Local taxes and shop materials can add a few dollars to the bill.
- Related repairs: If wiring harness damage or connector corrosion is found, or if timing cover removal is necessary, costs can increase.
In practice, total replacement costs typically range from about $70 to $300, with most cases landing near the $120–$260 mark depending on location, shop type, and parts choice.
DIY vs. professional replacement
Replacing a CMP sensor can be within reach for a mechanically inclined DIYer with basic tools, but accessibility varies by engine and model. Some Civic engines place the sensor in a harder-to-reach spot behind timing covers, which may require special tools and careful re-timing checks. If you’re unsure about electrical connectors, timing reference, or gasket seating, it’s prudent to have a professional perform the replacement to avoid timing or emission-related issues.
Summary
For a 2004 Honda Civic, anticipate a total cost in the ballpark of $70 to $300 for a camshaft position sensor replacement, factoring in sensor price, labor, and possible diagnostic or incidental charges. Parts typically account for $20 to $120, and labor commonly runs from $40 to $225 depending on shop rates and whether timing-cover work is required. Always obtain a written estimate and confirm whether diagnostic fees are waived if you proceed with the repair.
Bottom line: price varies by location, part choice, and whether additional work is needed, but most owners watching a 2004 Civic can expect a straightforward CMP sensor replacement to fall within a few hundred dollars at a typical shop.
