Knock Sensor 1 Circuit Low (Bank 1)
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?
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.
