How do you know there is something wrong with the Crankshaft Position Sensor on my Seat?

When the 'Check Engine' light on your dashboard is on. When the engine won't start or cuts out during operation. When the engine misfires. When the engine runs rough (a rough idle for example). When the car's fuel consumption is higher than usual.

When should you replace Seat Crankshaft Position Sensor?

As the sensor is located inside the crankcase it is especially prone to deterioration. It can be affected by oil or the significant temperature fluctuations inside the engine. The sensor can, eventually, fail completely, meaning that the engine's ECU is not provided with the information to optimise the combustion process. In turn this can lead to the fuel injection malfunctioning, preventing the appropriate amount of fuel to reach the engine to combust. It can lead the engine to misfire and run rough as well as cutting out or not starting at all. All leading to higher fuel consumption. For optimal combustion cycles in the engine it is therefore important to service the crankshaft position sensor as and when stipulated in the guidelines set out by your car's manufacturer. Professional and timely maintenance is essential to prevent further damage of other parts of the engine. Should you experience problems with a crankshaft position sensor, then it is advisable to have it inspected and, if necessary, have the sensor replaced.

What happens during a Crankshaft Position Sensor replacement on my Seat?

The mechanic will read the ECU for possible fault codes related to the sensor. The mechanic will inspect the sensor and ancillaries. If necessary, the mechanic will replace the sensor. The mechanic will check the system and will test drive the car to ensure proper operation of the engine. If necessary, the mechanic will make adjustments.
