Q: What does code P1372 mean?

Crankshaft Position Sensor Circuit Performance. P1372 on GM vehicles means the powertrain control module (PCM) has detected a performance problem with the crankshaft position (CKP) sensor circuit, typically an erratic or missing signal that does not match expected engine speed. The PCM compares the CKP signal to the camshaft position (CMP) sensor and ignition system timing, and flags this code when the correlation falls outside acceptable limits during cranking or running.
