Cylinder 1 Pressure Sensor Circuit Range/Performance
Cylinder 1 pressure sensor reads in range but plausibility check fails. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
