Part numbers vary by engine code; for a 2003 Civic there isn’t a single universal part number. The camshaft position sensor (CMP) you need depends on the engine family (D15, D16, D17, etc.) and the market your car was built for. If you share your engine code or VIN, I can identify the exact part number.
Engine options in the 2003 Civic
The 2003 Honda Civic was offered with several D-series variants in different markets. Each variant uses a CMP sensor that is matched to its specific engine design. Knowing the exact engine code is essential to selecting the correct part number.
- 1.5L D-series variants (common in base models in some markets) are among the engines used in 2003 Civics.
- 1.6L and 1.7L D-series variants (including the 1.7L used in many U.S. LX/EX trims) are also part of the 2003 lineup.
- Market-specific differences mean some regions used different D-series configurations for the same model year.
Because the CMP sensor is engine-family specific, confirming the exact engine code or VIN is the surest way to get the correct part number.
How to find the exact part number
To identify the precise CMP sensor part number for your car, follow these steps. This will ensure you order the correct sensor that fits and functions properly.
- Determine your engine code. Look for the engine identifier stamped on the engine block or check the vehicle’s engine bay label that lists the code (for example, D15B, D16Y7, D17A1, etc.).
- Use the engine code to search the official Honda OEM parts catalog or a trusted parts retailer. Enter the code and select your model year (2003 Civic) to pull the CMP sensor listing.
- Compare the listing’s part number and the sensor’s connector, mounting orientation, and electrical connector with the sensor in your car to confirm a match.
Using the exact part number from the catalog protects against fitment issues and ensures proper sensor operation, especially since CMP sensors can vary by connector type and mounting.
Where to buy or verify the part
If you prefer alternative routes to confirm the part number, these options can help you verify before purchasing.
- Official Honda parts dealerships or their online parts portals, which allow VIN-based or engine-code-based searches.
- Reputable aftermarket retailers that cross-reference CMP sensors for Honda D-series engines; always compare connectors and mounting against your current sensor.
- Local auto parts stores with a parts lookup system that supports Honda vehicles; bring your VIN or engine code for accuracy.
Cross-checking across multiple sources can help verify the correct part number, especially if the vehicle was imported or modified for a different market.
Summary
For a 2003 Honda Civic, there isn’t a single CMP sensor part number. The correct PN depends on the engine code (D15, D16, D17, etc.) and the market. The best approach is to identify the exact engine code or VIN, then consult the official Honda OEM catalog or a trusted retailer to pull the precise part number that matches your car’s CMP sensor, connector, and mounting. If you share your engine code or VIN, I can help pinpoint the exact part number for you.
