The Engine Control Module (ECM) uses water in fuel sensor/switch to monitor the water level in the fuel pre-filter. When it is time for drainage a water level warning is indicated in the instrument. It?s possible to activate the function when draining is needed. When the function is activated the water in fuel valve is opened and the water drained from the fuel system. Faulty water in fuel valve can lead to that the valve is constantly shut. Conditions for diagnostic trouble code (DTC):1) Short circuit to battery voltage on A14.EA:3 Diagnostic operating conditions1) Ignition key in ON position Observable...

The camshaft position (CMP) sensor is an inductive device. As the camshaft turns, the tip of the CMP sensor senses the teeth of the tone wheel fastened to the camshaft vibration damper. The CMP sensor sends a series of voltage pulses to the Engine Control Module (ECM). The frequency of the pulses is translated into engine speed (RPM) and position by the ECM. The ECM uses this information along with the information from Crankshaft Position (CKP) sensor to synchronize fuel injection. Conditions for diagnostic trouble code (DTC):1) The camshaft position sensor (CMP) signal has incorrect timing compared to the crankshaft...
