Standard Ignition KS201 sensor for the 1990-1998 Saab 9000 4-cylinder 2.3L detects engine knock and sends a voltage signal to the engine computer.
Engine pinging under load, reduced power or a lit check engine light can mean the knock sensor is worn. Spark plugs, a damaged connector or wiring can be behind the same signs, so find the cause before buying a new sensor.
This sensor is a direct-fit replacement for the 1990-1998 Saab 9000 4-cylinder 2.3L (L4-2.3L), which takes one.
