Power Steering Pressure Sensor Circuit

30 brands affected · Generic SAE J2012 description.

Key terms: SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions

Safety: This code relates to the steering system. Power steering assistance may be reduced or fail.

1What it means in plain English

This range covers vehicle speed, idle and oil-pressure control, charging-system voltage, and brake-switch circuits.

2Common causes

  1. Carbon build-up in the throttle body
  2. Faulty idle air control valve
  3. Faulty vehicle speed sensor
  4. Faulty charging system or weak battery
  5. Wiring or connector fault

3Can I drive?

Serious · drive with care

If the steering feels heavy or unpredictable, stop safely and have the car recovered. Steering assistance can fail suddenly.
