Power Steering Pressure Sensor Circuit Low Input
PS pressure sensor signal voltage below threshold — open, short to ground, 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.
Affected components
- Power steering pressure sensor
- Ps sensor wiring
Common causes
- High likelihood: Sensor circuit shorted to ground or open
- Low likelihood: Connector pins corroded - high contact resistance
- Low likelihood: Harness chafing through insulation
Diagnostic notes
- The malfunction indicator lamp may illuminate
