The crankshaft position sensor (CKP) on a 2015 Honda Civic is mounted on the front of the engine block near the crankshaft pulley, behind the lower splash shield. It’s a small sensor with an electrical connector that runs up toward the engine bay.
In the 2015 Civic, this sensor sits at the front of the engine near the timing cover and crank pulley. The exact spot can vary slightly by market and engine option, but the CKP is typically found in this front-face area of the block and is accessible after removing the undertray or splash shield.
Where to look on the 2015 Civic
The CKP sensor is normally mounted on the front face of the engine block near the crank pulley and timing cover. It is a small sensor that protrudes into a recess on the block and has a connector that runs up into the engine bay. Access usually requires removing the front undertray or splash shield for visibility.
For most 2015 Civics equipped with the common 1.8L engine, this is the typical location. Some markets or trims with different powertrains may place the sensor slightly elsewhere on the front of the block or near the timing cover, but the general area remains the same.
- Front of the engine block, near the crankshaft pulley and timing cover
- Mounted in a small boss on the block with a short harness
- Electrical connector runs toward the engine bay, often toward the passenger side
Concluding note: If you can't locate it in this zone, double-check your model/engine code (R18A1 for most US 2015 Civics) and consult the official service manual for your VIN.
How to access and inspect the CKP sensor
To locate, inspect, or replace the CKP sensor, you typically need to gain access from underneath or from the wheel well by removing shielding. Always work with the engine off and the battery disconnected.
- Disconnect the negative battery terminal to prevent electrical shorts.
- Raise the car and remove the front undertray or splash shield to expose the front of the engine.
- Locate the CKP sensor near the crank pulley area on the front of the engine block.
- Carefully unplug the sensor’s electrical connector and inspect the wiring for damage or corrosion.
- Unbolt and remove the sensor if replacement is needed, then install the new unit with proper torque and reattach the connector.
- Reconnect the battery, start the engine, and verify proper operation (no fault codes, smooth idle).
Concluding: Proper inspection and replacement follow the steps above, with attention to connector orientation and sealing to avoid water intrusion.
Engine variants and caveats
Note: The 2015 Civic in the United States primarily uses the 1.8L R18A1 engine; other markets or later trims may use different engines (such as a 1.5L turbo). The CKP sensor generally sits near the front of the engine block near the crank pulley, but the exact mounting geometry can differ by engine code and timing cover design. Always verify with your specific VIN and engine code.
- R18A1 1.8L engine (common in US 2015 Civics): CKP located at the front of the engine block near the crank pulley.
- Other engines for the Civic line (e.g., later 1.5L turbo variants): CKP location may differ slightly, typically still near the timing cover, so consult the service manual for exact placement.
Conclusion: If you’re troubleshooting, start with the front-of-block area near the crank pulley, and consult your VIN-specific manual for any variant differences.
Summary
For a 2015 Honda Civic, the crankshaft position sensor is typically found on the front face of the engine block near the crankshaft pulley and timing cover, usually accessible after removing the front undertray. Variations can occur depending on engine type or market, so always confirm with your vehicle’s VIN and engine code in the official manual. This location is the starting point for diagnosis, testing, or replacement.
Where is the radar sensor on a 2020 Honda Civic?

Does a 2015 Honda Civic have a catalytic converter?
The catalytic converter is a part of your 2015 Honda Civic's exhaust system.
What side is the crankshaft position sensor on?
The location of the crankshaft position sensor can vary from one vehicle to another. Obviously it must be close to the crankshaft, so it is most often located on the front underside of the engine. It can usually be found mounted to the timing cover. Sometimes it may be mounted at the rear or the side of the engine.
