Crankshaft Position Sensor 911 1984-89

Description

If you are noticing engine vibrations, misfires and even backfiring your crankshaft position sensor maybe bad. Your car's DME (ECU) uses the signal from the crankshaft position sensor to control ignition timing and fuel injection, so if your sensor is failing your engine is suffering from poor timing and is not running efficiently.

Sold individually. 2 Necessary per car.
