Troubleshooting Section
If the preceding codes are logged, an intermittent
condition may be causing the logged codes.
Refer to Troubleshooting, "Electrical Connectors
- Inspect".
Perform a "Wiggle Test" by using the Perkins
Electronic Service Tool (EST) in order to identify
intermittent connections.

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.
