How does this sensor affect engine performance?

The crankshaft position sensor provides the engine control module (ECM) with the crankshaft’s position and RPM, which the ECM uses to time fuel injection and ignition events. A correct, steady signal prevents misfires, rough idling, and timing errors that can impact drivability. Replacing a faulty sensor can return engine response and stability to expected levels.

• Supplies accurate crank angle and rotational speed data to the ECM
• Helps maintain correct ignition and fuel injection timing
• Reduces drivability issues like stalling, misfires, and hesitation

Will this part fit my vehicle and install easily?

After replacement, re-scan the vehicle to confirm the ECM receives correct signals and codes do not reappear.

• Can resolve P0335/P0336-style codes tied to crankshaft signal faults
• Recommend scanning and clearing codes after replacement
• Verify sensor signal with diagnostic tools if codes persist
