Question
What causes power steering pressure sensor "erratic readings"?
Answer
Loose sensor mounting and damaged wiring insulation.
Explain
Erratic readings cause variable steering assist. CHEPQ tools check sensor mounting torque (15-20 ft-lbs) and wiring insulation—securing the sensor and repairing wires resolves the issue.
