Fiat Palio Siena Crankshaft Position Sensor (Pick Up)

OE 46442091

Nationwide Delivery - Door to Door


This is a brand new, affordable OE Specification aftermarket replacement product. 100% Factory tested and built to strict quality control standard to ensure high performance and guaranteed to deliver better fuel economy.


The Crankshaft Position Sensor is used to detect engine speed / engine rotation position. They allow the ECU to change the injector opening; spark timing in various engine conditions.


Defective Symptoms

If this sensor fails, you may notice hard starting conditions, lack of power, stalling or a complete failure to start. The Crank sensor monitors the position and rotational speed of the engine to determine timing for ignition. If it is not functioning, you will not get a signal to ignite the spark plugs.

Food for Thought

The functional objective for the crankshaft position sensor is to determine the position and/or rotational speed (RPM) of the crank. Engine Control Units use the information transmitted by the sensor to control parameters such as ignition timing and fuel injection timing. The sensor output can also be related to other sensor data including the cam position to derive the current combustion cycle, this is very important for the starting of a four stroke engine.

Sometimes the sensor may become burnt or worn out. The most likely causes of crankshaft position sensor failure are exposure to extreme heat when you have a gasket or crank problem, corruption from oil or other engine fluids that leaked onto the sensor, or wear over a long period of time. When it goes bad, it stops transmitting the signal which contains the vital data for the ignition and other parts in the system.

A bad crank position sensor can worsen the way the engine idles, the pistons fire, or the acceleration behavior. If the engine is revved up with a bad or faulty sensor, it may cause misfiring, motor vibration or backfires. Accelerating might be hesitant, and abnormal shaking during engine idle might occur. In the worst case the car may not start.
