2003 Chrysler 300M Problems

Damaged Cam Position Sensor May Cause Engine Problems

A damaged cam position sensor (or its wires and connector) can cause intermittent stalling, stumbles, or hard starting.

Key May Not Turn or be Removed Due to Wear/Failed Lock Cylinder

If the ignition key does not turn and/or cannot be removed, a new lock cylinder may be needed. A worn key can also cause similar problems.

Stalling or Low Engine Idle Speed Due to Dirty Throttle Body

A dirty throttle body may cause low engine idle speed or frequent stalling, as oily residue blocks air flow in the throttle when the throttle is closed. Throttle body cleaning may be necessary to correct this condition. Our technicians caution against spraying cleaner directly onto the throttle body as this may damage the throttle position sensor (TPS).
