The P1336 code indicates that the input signal from the crankshaft position (CKP) and/or camshaft position (CMP) sensor to the Powertrain Control Module (PCM) is erratic. Possible causes include a damaged PCM, faulty CKP or CMP sensors, base engine issues, or wiring harness problems. Recommended troubleshooting steps: inspect the harness for routing errors, physical damage, improper shielding, or electrical interference from other malfunctioning systems.
