The P1351 fault code indicates a problem with the Ignition Control Module (ICM) circuit, specifically a high voltage issue. The ICM has its own power and ground circuits, and it communicates with the Powertrain Control Module (PCM) through various circuits. These circuits include the ignition control timing signal, IC timing control, low and medium resolution engine speed signals, camshaft position signal, and low reference.

During engine cranking, the ICM sends 3X signals to the PCM and controls the timing advance. After the PCM receives the second 3X signal and applies 5 volts to the IC timing signal circuit, the timing advance shifts to PCM control.

The ICM also monitors the CKP sync signal during cranking, which helps determine the correct cylinder pair and initiate the ignition coil firing sequence. The CKP sensor, which shares a 12 volt reference and low reference circuit with the CMP sensor, plays a crucial role in providing the necessary signals to the ICM. In summary, the P1351 fault code suggests a high voltage issue in the Ignition Control Module circuit, affecting the timing advance and ignition coil firing sequence.

What are the possible causes of the automobile fault code P1351?
