Cylinder 12 Pressure Sensor Circuit Intermittent or Erratic
Cylinder 12 pressure sensor signal jumps or drops out intermittently — connector or wiring issue. 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.
