Power Steering Pressure Sensor Circuit Fault
There’s a problem with the power steering pressure sensor circuit.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The power steering pressure sensor is either having trouble sending the right signal or the wiring to it is bad, making it think the pressure is wrong.
What the computer is actually seeing
The computer monitors the sensor signal voltage which should fluctuate between 0.5V and 4.5V based on system pressure. If it's out of this range or static, a fault is logged.
What a healthy reading looks like
Normal signal voltage should read between 0.5V (low pressure) and 4.5V (high pressure).
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check power steering fluid level; it should be within the recommended range. If low, top off and monitor for a return of the code.
- 2Inspect wiring and connectors to the power steering pressure sensor for signs of corrosion or damage. Repair as needed.
- 3Use a multimeter to check the voltage at the power steering pressure sensor connector while the engine is running; it should fluctuate between 0.5V and 4.5V. If it is outside this range, replace the sensor.
Common causes
- Corroded wiring or terminals in the power steering circuit
- Faulty power steering pressure sensor
- Low power steering fluid level
