Knock Sensor 1 Circuit Range/Performance (Bank 1)

34 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

Worn or fouled spark plug
Faulty ignition coil
Vacuum or intake air leak
Low fuel pressure
Faulty crankshaft or camshaft position sensor
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.
