Beck/Arnley Ignition Knock (Detonation) Sensor P/N:158-1793
Beck/Arnley 158-0990 ignition knock (detonation) sensor for the 2000-2005 Volkswagen Passat 4-cylinder 1.8L and other vehicles senses engine knock from its spot in the cylinder block and reports it to the engine computer.
A lit check engine light or pinging under load can mean this sensor is worn, though a damaged wiring connector or the engine control unit can be behind the same signs.
The 2001-2006 Audi A4 4-cylinder 1.8L and the 2002-2005 A4 V6 3.0L are among the vehicles this knock sensor fits, and it matches OE form, fit and function on them. This listing is one sensor: the 4-cylinder 1.8L takes one and the V6 2.7L and 3.0L engines take two.
