Manual Extract: POS Sensor Warning

This manual section discusses the conditions and potential issues related to the POS (Position) Sensor in the crankshaft. An improperly functioning POS sensor can result in:

• Incomplete signal detection during engine startup
• Anomalous wave detection during engine operation
• Possible misfire or power loss leading to engine control module (ECM) code setting

Several conditions may trigger this code, such as:

• Failure of an ignition coil or spark plug
• Low compression in a cylinder causing interference in engine rhythm
• Speed variances detected among cylinders

Once the ECM reaches its maximum adjustment capability, it will issue this code, and the MIL (Malfunction Indicator Lamp) will illuminate, indicating the need for diagnosis.

The POS sensor integrates with a phase sensor in synchrony to monitor and adjust engine functions such as speed, timing, and engine position, contributing critically to overall engine performance.
