III. The engine is being serviced for active boost pressure sensor diagnostic faults and there are no wiring, ECM, or connector problems as determined by following proper troubleshooting procedures (sensor replacement should only take place if the diagnostic fault is still active after this procedure has been completed). Rework Procedure
1. Turn the ignition key OFF, engine OFF.2. Disconnect the engine harness from the ECM (J2/P2 connector).3. One at a time, remove the wires designated in Table 1 from the P2 connector and insert the corresponding wire from the 1387020 Harness Assembly into the P2 connector. (See Illustration 1).Sensor and Labor to troubleshoot and R&I must be claimed as standard warranty.
