Test Description
Number(s) below refer to the step number(s) on the Diag-
nostic Table.
1. The On–Board Diagnostic (EOBD) System Check
prompts the technician to complete some basic
checks and store the freeze frame and failure re-
cords data on the scan tool if applicable. This
creates an electronic copy of the data taken when
the malfunction occurred. The information is then
stored on the scan tool for later reference.
2. This step determines if DTC P0341 is the result of
a hard failure or an intermittent condition.
3. The counter should stop incrementing with the sen-sor electrical connector disconnected and set a
DTC P0342 with the sensor disconnected. If it still
increments the ECM is malfunctioning.
4. By moving the CMP sensor electrical connector, the
connections at the sensor are checked. Make sure
the electrical connector remains securely fastened.
5. A poor connection in any of the circuits at the CMP
will cause the CMP Resync Counter to increment.
Anytime a poor connection is present, the CMP
Reference Activity counter will stop incrementing
and the CMP Resync Counter will increment.
8. The replacement ECM must be reprogrammed.
Refer to the latest Techline procedure for ECM re-
programming.

S Damaged harness – Inspect the wiring harness for
damage. If the harness appears to be OK, discon-
nect the ECM, turn the ignition on, and observe a
voltmeter connected to the 58X reference circuit at
the ECM harness connector while moving connec-
tors and wiring harnesses related to the ECM. A
change in voltage will indicate the location of thefault.
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.
