Standard Ignition Engine Crankshaft Position Sensor P/N:PC990
Keep the ignition and fuel-injection timing synced with the Standard Ignition Engine Crankshaft Position Sensor PC942, a direct-fit replacement for the 2004 Audi A4 (L4-1.8L) and 2005-2008 Audi A4 (L4-2.0L). This sensor reads the position and rotational speed of the crankshaft and feeds that signal to the engine control module, which the ECM uses to time spark and injector events.
What it does: monitors crankshaft position and speed so the ECM can coordinate ignition timing and fuel delivery.
Signs this crankshaft position sensor may need replacing: a no-start or hard-start condition, intermittent stalling, hesitation, or a stored crankshaft-position trouble code. Because these symptoms can have other causes, diagnose the fault before replacing — if a failed crankshaft position sensor is confirmed, this PC942 replaces it. Sold individually; refer to the vehicle service information for the correct installation and any related fasteners and whether they may be reused.
What does the Standard Ignition PC942 crankshaft position sensor do?
It monitors the crankshaft's position and rotational speed and sends that signal to the engine control module, which uses it to time ignition and fuel injection.
Which vehicles does the PC942 fit?
It is a direct-fit replacement for the 2004 Audi A4 with the L4-1.8L engine and the 2005-2008 Audi A4 with the L4-2.0L engine. See the Buyer's Guide tab to confirm your vehicle.
What are the signs of a failing crankshaft position sensor?
Common signs include a no-start or hard-start condition, intermittent stalling, hesitation, or a stored crankshaft-position trouble code. Diagnose the cause before replacing.
Is this the same as a camshaft position sensor?
No. This PC942 is a crankshaft position sensor that reads the crankshaft; a camshaft position sensor reads the camshaft. They are separate components.
How many sensors do I need?
This listing is for one sensor, and the listed applications use a quantity of one. Refer to the service information for correct installation.
