26 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

Carbon build-up in the throttle body
Faulty idle air control valve
Faulty vehicle speed sensor
Faulty charging system or weak battery
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.
