Fuel Delivery Error

33 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

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

  1. Dirty or faulty mass air flow sensor
  2. Vacuum or intake air leak
  3. Weak fuel pump or clogged fuel filter
  4. Faulty fuel injector
  5. Faulty oxygen sensor
  6. Wiring or connector fault

3Can I drive?

Caution · drive with care

Have it diagnosed if the engine runs badly or the code keeps returning. Because this range includes coolant temperature sensors, watch the temperature gauge: if it climbs into the red, or the engine overheats or stalls, stop safely and get professional help.

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.
