1F – 268 ENGINE CONTROLS
CAMSHAFT POSITION (CMP) SENSOR NO SIGNAL
System Description
The Camshaft Position (CMP) Sensor is used to corre-
late crankshaft to camshaft position so that the
engine control module
(ECM) can determine which cylinder is ready to be
fueled by the injector. The CMP is also used to deter-
mine which cylinder is misfiring when misfire is present.
If the ECM receives an intermittent signal from the
CMP, then the CMP Resync Counter will increment.
When the ECM cannot use the information from
the CMP sensor, a Diagnostic Trouble Code (DTC) is
set and the ECM will fuel the engine using the Al-
ternating Synchronous Double Fire (ASDF) method.
Conditions for Setting the DTC
Engine is running.
DIAGNOSTIC TROUBLE CODE (DTC) P0342
Action Taken When the DTC Sets
The ECM will illuminate the Malfunction Indica-
tor Lamp (MIL) the first time the fault is detected.
The ECM will record operating conditions at the
time the diagnostic fails. This information will be
stored in the Freeze Frame and Failure Records buff-
ers.
A history DTC is stored.
Conditions for Clearing the MIL/DTC
The MIL will turn off after three (four –
1.5L SOHC) consecutive ignition cycles in which the
diagnostic runs without a fault.
A history DTC will clear after 40 consecutive warm up
cycles without a fault.
