Engine Oil Temperature Sensor A Circuit

31 brands affected · Generic SAE J2012 description.

Key terms: Oxygen sensor: measures oxygen in the exhaust gas · Mass air flow sensor: measures the air going into the engine · SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions

Safety: This code relates to engine oil pressure or oil level. Low oil pressure can destroy the engine within minutes.

1What it means in plain English

This code is in the fuel, air and oxygen sensor range, which also includes coolant temperature faults.

2Common causes

Dirty or faulty mass air flow sensor
Vacuum or intake air leak
Weak fuel pump or clogged fuel filter
Faulty fuel injector
Faulty oxygen sensor
Wiring or connector fault

3Can I drive?

Serious · drive with care

Stop the engine as soon as it is safe and do not drive until it has been checked. Low oil pressure or a low oil level can destroy the engine within minutes.
