Conduct an appropriate pull test on wires in the ENG-P2 and ENG-P1 connectors
to ensure wires are tight and secure.
STEP 4.
Disconnect ENG-P2 from ECM J2, ENG-P201 from the oil pressure sensor, and
ENG-P202 from the fuel pressure sensor. Verify continuity from ENG-P201-A to
ENG-P202-A and ENG-P2-2. Verify continuity from ENG-P201-B to ENG-P202-
B and ENG-P2-3. Verify continuity from ENG-P201-C to ENG-P2-24.
STEP 5.
Check the wires on both ENG-P1 and ENG-P2 harnesses for abrasion and pinch
