Engine Coolant Temperature Circuit Low Input

44 brands affected · Generic SAE J2012 description.

Key terms: Control module: a small computer that runs one part of the car · SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions

Safety: This code relates to engine cooling or temperature. Overheating can damage the engine.

1What it means in plain English

The coolant temperature sensor signal is lower than the range the engine computer considers possible, which can make the engine run rich.

2Common causes

Faulty coolant temperature sensor
Low coolant level
Damaged wiring or connector
Corroded sensor connector
Engine control module fault

3Can I drive?

Caution · drive with care

Watch the temperature gauge and have it checked soon. If the engine overheats, the gauge reads high, or steam appears, stop safely and let it cool.

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.
