6E–119 4JX1–TC ENGINE DRIVEABILITY AND EMISSIONS
Diagnostic Trouble Code (DTC) P0341 (Flash DTC 41)
CMP (Cam Position) Sensor Out of Synchro
060RW133
Circuit Description
The CMP signal is produced by the camshaft position
(CMP) sensor pulses when the engine is running and
crankshaft position (CKP) sync pulses are also being
received. The Engine Control Module ECM uses the
CMP signal pulses to initiate sequential fuel injection. If
the ECM receives an incorrect number of pulses on the
CMP reference circuit, DTC P0341 will set.
Action Taken When the DTC Sets
The ECM will store conditions which were present
when the DTC was set as Freeze Frame and in the
Failure Records data.
Conditions for Clearing the MIL/DTC
DTC P0341 can be cleared by using the Tech 2 “Clear
Info” function or by disconnecting the ECM battery
feed.
Diagnostic Aids
An intermittent may be caused by a poor connection,
rubbed–through wire insulation or a wire broken inside the
insulation. Check for:
Poor connection — Inspect the ECM harness and
connectors for improper mating, broken locks,improperly formed or damaged terminals, and poor
terminal-to-wire connection.
Damaged harness — Inspect the wiring harness for
damage. If the harness appears to be OK, disconnect
the ECM, turn the ignition on and observe a voltmeter
connected to the CMP signal circuit at the ECM
harness connector while moving connectors and
wiring harnesses related to the ICM and the CMP
sensor. A change in voltage will indicate the location
of the fault.
Reviewing the Failure Records vehicle mileage since the
diagnostic test last failed may help determine how often
the condition that caused the DTC to be set occurs. This
may assist in diagnosing the condition.
Test Description
Number(s) below refer to the step number(s) on the
Diagnostic Chart.
2. Ensures that the fault is present.
12.Determines whether the fault is being caused by a
missing camshaft magnet or a faulty sensor. The
voltage measured in this step should read around 4
volts, toggling to near 0 volts when the CMP sensor
interfaces with the camshaft magnet.

Diagnostic Trouble Code (DTC) P0342 (Flash DTC 41)
CMP (Cam Position) Sensor No Signal
060RW133
Circuit Description
The CMP signal produced by the camshaft position
(CMP) sensor pulses when the engine is running and
crankshaft position (CKP) synchro pulses are also being
received. The hall type CMP sensor and the CKP sensor
share 5 V and ground connections at the Engine Control
Module ECM. The third wire at the sensor is a signal
c i r c u i t t o t h e E C M . T h e E C M u s e s t h e C M P s i g n a l p u l s e s
to initiate sequential fuel injection. If the ECM does not
receive pulses on the CMP reference circuit, DTC P0342
will set.
Action Taken When the DTC Sets
The ECM will store conditions which were present
when the DTC was set as Freeze Frame and in the
Failure Records data.
Conditions for Clearing the MIL/DTC
DTC P0342 can be cleared by using the Tech 2 “Clear
Info” function or by disconnecting the ECM battery
