Camshaft Position Sensor
A sensor that determines camshaft rotation for precise valve timing control.
The camshaft sensor works together with the crankshaft sensor to manage sequential fuel injection and variable valve timing. It helps the ECU identify which cylinder is firing. A faulty cam sensor can cause hard starting, stalling, or incorrect timing adjustments. Replacing or cleaning the sensor restores smooth performance. Testing with a scan tool or scope verifies signal integrity. Accurate timing information ensures maximum efficiency and engine protection.
