Camshaft Position Sensor A Circuit Low Input (Bank 1)

37 brands affected · Generic SAE J2012 description.

Key terms: Catalytic converter: cleans the exhaust gases · Bank 1: the side of the engine containing cylinder 1 · SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions

1What it means in plain English

This range covers ignition and engine-speed signals, including misfires and crankshaft or camshaft position sensors.

2Common causes

  1. Worn or fouled spark plug
  2. Faulty ignition coil
  3. Vacuum or intake air leak
  4. Low fuel pressure
  5. Faulty crankshaft or camshaft position sensor
  6. Low engine compression

3Can I drive?

Serious · drive with care

A failing crankshaft or camshaft sensor can cut the engine without warning, and a flashing check-engine light points to a misfire that can damage the catalytic converter. If the light is flashing, stop as soon as it is safe and have the car towed. Otherwise drive gently to a workshop; if it stalls or will not restart, have it towed.

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.
