Hella Crankshaft Position Sensor - 6PU 009 146-561

The crankshaft position sensor monitors the speed and position of the crankshaft. This information is sent to the engine control unit (ECU) to determine ignition timing and fuel injection, which are crucial for the engine to run smoothly and efficiently.

Common symptoms include: difficulty starting the engine, engine cranking but not starting, stalling while driving, rough idling, poor acceleration, and a Check Engine Light illumination. A diagnostic scan can often confirm a faulty sensor.

No, it is specifically designed for certain Saab 9-3 (YS3F) models from 2004-2015 with the 1.9 TiD engine (88KW 120HP). It is crucial to verify your vehicle's exact specifications before purchasing.

OE-quality means the part is manufactured to meet or exceed the standards set by the original equipment manufacturer. This ensures it performs comparably to the part that originally came with the vehicle.

The product description states 'without cable,' indicating that the sensor is supplied without an integrated or separate wiring harness. You will typically use your vehicle's existing wiring harness and connector.

Installation complexity can vary by vehicle. If you have automotive repair experience and the necessary tools, it may be a DIY task. However, it is often recommended to have a qualified mechanic perform the installation to ensure proper fitment and function.

This Hella Crankshaft Position Sensor operates at 12V and has a resistance of 900 Ohms.

A common cause for the Check Engine Light is a faulty crankshaft position sensor. If symptoms like poor starting or stalling are present, this sensor may need replacement after proper diagnosis.

The ECU relies on the crankshaft sensor signal to initiate fuel injection and ignition. If the sensor fails or sends an incorrect signal, the engine may crank but not start. Verify the sensor's connection and consider replacement if diagnostic tests indicate a fault.

An intermittent or failing crankshaft sensor can cause inconsistent engine performance, leading to stalling or hesitation. Ensure the sensor is properly seated and that there are no obstructions or damage to its wiring or connector.

Incorrect timing information from a faulty crankshaft sensor can result in rough idling or engine misfires. A thorough diagnostic check is recommended to confirm the sensor's role in these symptoms.
