Thermostat Heater Control Circuit Low

33 brands affected · Generic SAE J2012 description.

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

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?

Caution · drive with care

Codes in this range include oil-pressure, brake-switch and charging-system voltage faults. If the oil-pressure warning light is on, stop the engine as soon as it is safe and do not drive until it is diagnosed. If the battery or charging warning light is on, drive straight to a workshop: the car can stall when the battery runs flat. For any other P05 code, have the car diagnosed promptly rather than continuing to drive.

This page gives general information. It is not professional advice. For a definite diagnosis and a repair quote, ask a qualified mechanic to inspect the car.
