Power Steering Pressure Sensor Circuit High Input
PS pressure sensor signal voltage above threshold — short to supply or sensor failure. 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.
