Keep your engine's ignition timing and fuel delivery synchronized with the Standard Ignition Engine Crankshaft Position Sensor PC942. It drops in as a direct-fit replacement for the 2004 Audi A4 (L4-1.8L) and the 2005-2008 Audi A4 (L4-2.0L), reading crankshaft rotation and position so the engine control module can command spark and injector events accurately.
- Function: Monitors crankshaft speed and position and sends that signal to the engine control module for ignition and fuel-injection timing.
- Direct-fit application: Designed to replace the original crankshaft position sensor on the listed Audi A4 applications.
- Signs it may need replacing: Hard starting, no-start, stalling, intermittent misfire, or an illuminated check engine light can point to a failing crankshaft position sensor.
If a faulty crankshaft position sensor is the cause of your drivability trouble, PC942 replaces it. Because these symptoms can have other causes, diagnose the fault before replacing. Sold individually.
Fitment: 2004 Audi A4 [L4-1.8L]; 2005-2008 Audi A4 [L4-2.0L]. See the Buyer's Guide tab to confirm your vehicle.
Manufacturer part number PC942.
