The P1350 code indicates a Bypass Line Monitor Malfunction in the ignition system. The engine computer is not receiving the correct feedback signal needed to properly manage ignition timing.
Common Causes:
-
Faulty Ignition Control Module (ICM): The module is failing to send the required signal.
-
Wiring Issues: Corroded, broken, or loose connections in the ignition harness.
-
Ignition Coil Failure: Internal electrical issues within the coil pack.
Troubleshooting Steps:
-
Inspect Wiring: Check the ignition module harness for damaged wires or corroded pins.
-
Verify Power/Ground: Use a multimeter to confirm the ICM is receiving proper power and ground.
-
Test Components: Test the ignition coils and module resistance against your vehicle’s service manual specifications.
