A.
Thoroughly inspect the terminal connections on
the P2/J2 ECM sensor connectors.
B.
Thoroughly inspect the following engine pressure
sensor connectors:
•
P201 Engine Oil Pressure Sensor
•
P228 Fuel Rail Pressure Sensor
•
P200 Intake Manifold Pressure Sensor
C.
Refer to Troubleshooting, “Electrical Connectors
- Inspect”.
D.
Perform a 45 N (10 lb) pull test on each of the
wires in the ECM connector and the sensor
connectors that are associated with the active
diagnostic code.
E.
Check the screw for the ECM connector for the
correct torque of 5 N·m (44 lb in).
F.
Check the harness for abrasions and for pinch
points from the sensors back to the ECM.
G.
Use the electronic service tool to perform a
“Wiggle Test”. The “Wiggle Test” will identify
intermittent connections.
Expected Result:
All connectors, pins, and sockets should be
completely coupled and inserted. The harness should
be free of corrosion, abrasions and pinch points.
Results:
•
OK
–
Proceed to Test Step 3.
•
Not OK
Repair:
Repair the connectors or the harness
and/or replace the connectors or the harness.
Ensure that all of the seals are correctly in place
and ensure that the connectors are completely
coupled.
Use the electronic service tool in order to clear all
logged diagnostic codes and then verify that the
repair eliminates the fault.
STOP.
Test Step 3. Verify that the Diagnostic
Code is Still Active
A.
Turn the keyswitch to the ON position. Wait at
least 10 seconds for activation of the diagnostic
codes.
