DIAGNOSTIC TROUBLE CODE (DTC) – P0342 CAMSHAFT POSITION SENSOR
NO SIGNAL
Circuit Description
The Camshaft Position Sensor is used to detect Cam-
shaft position and to have correlation with Crankshaft
position so that the ECM can determine which cylinder is
ready to be fueled by the injector. The polarity of cam-
shaft sensor signal must be changed only once per
crankshaft position.
Conditions for Setting the DTC
D Engine is running.
D No traction of CMP signal between teeth 18 and 82
but change in polarity.
Action Taken When the DTC Sets
D The Malfunction Indicator Lamp (MIL) will illuminate.
D The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.
D A history DTC is stored.
Conditions for Clearing the MIL/DTC
D The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.
D A history DTC will clear after 40 consecutive warm-up
cycles without a fault.
D DTC(s) can be cleared by using the scan tool.
DIAGNOSTIC AIDS
