The crankshaft position sensor on a 2001 Honda Accord is located at the front of the engine near the crank pulley and timing cover. On four‑cylinder models it sits in or on the timing cover by the crank pulley; on V6 models it likewise sits near the belt drive area at the front of the engine. If you’re diagnosing starting or stalling issues, check the sensor and its wiring with a service manual or scan tool.
Engine variants and sensor placement
Four-cylinder (2.3L) location
In the four‑cylinder 2001 Accord, the crank sensor is mounted at the front of the engine block, adjacent to the timing belt cover and near the crank pulley. Access is commonly gained from beneath the vehicle after removing the splash shield, though some setups allow top access after removing engine coverings.
Before you inspect the sensor, the following points describe common mounting details you should expect.
- Located in a small hole on the timing cover or engine block near the front crank pulley.
- Sensor tip faces the crankshaft gear to read the tone wheel (reluctor) on the crank.
- Wiring harness usually routes toward the main engine harness; connectors are typically two- or three-wire types.
- Replacement requires aligning the sensor with its mounting hole and torquing to specification.
Understanding this placement helps you plan inspection or replacement and reduces the risk of damaging surrounding parts.
V6 (3.0L) location
The V6 version also places the crank sensor on the front of the engine, near the belt drive and timing cover area. The exact mounting point can vary by production run, but you’ll typically find a small sensor on the front of the block facing the crank pulley with a short harness running toward the engine bay wiring.
The following details outline typical features to look for in the V6 setup.
- Sensor sits near the front lower block or timing cover, close to the crank pulley.
- Reads a tone wheel on the crankshaft and sends a signal to the ECU.
- Wiring harness runs toward the engine harness; expect a multi-wire connector.
- Keep the sensor and its socket clean from oil and debris during inspection or replacement.
Knowing this approximate location helps you locate the CPS for testing or replacement on the V6 engine.
What to check when locating and diagnosing
If you are troubleshooting, inspect the area for oil leaks, corrosion on the connector, damaged wiring, or a loose sensor. A diagnostic code such as P0335 (Crankshaft Position Sensor) or a no-start condition may point to the CPS, but other sensors and electrical issues can mimic the symptoms. Always confirm with the factory service manual or OEM diagrams for your specific VIN and engine code.
Summary
For a 2001 Honda Accord, the crankshaft position sensor is located at the front of the engine near the crank pulley and timing cover. The exact mount point varies slightly by engine option: the four‑cylinder is typically mounted on the front timing cover by the crank pulley, while the V6 follows a similar front‑of‑engine placement near the belt drive area. Verifying the precise mounting with the service manual and inspecting the wiring are essential steps in diagnosing CPS-related issues.
