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

Engine is running.

No traction of CMP signal between teeth 18 and 82
but change in polarity.
Action Taken When the DTC Sets

The Malfunction Indicator Lamp (MIL) will illuminate.

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.

A history DTC is stored.
Conditions for Clearing the MIL/DTC

The MIL will turn off after four 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.

DTC(s) can be cleared by using the scan tool.
DIAGNOSTIC AIDS
Check and correct any abnormal engine noise before
using the diagnostic table.
Any circuitry that is suspected as causing engine noise
complaint should be thoroughly checked for the follow-
ing conditions :

Backed-out terminals.

Improper mating.

Broken locks.

Improperly formed.

Damaged terminals.

Poor terminal-to-wire connections.

Physical damage to the wiring harness.
