Crankshaft repair & replacement made easy

The crankshaft position sensor measures the position of the camshaft inside the cylinder head. From this information it can be derived by the engine's computer (ECU) which cylinder is firing. Together with the information of the camshaft position sensor the ECU can the adjust the fuel injection system and engine coil firing sequence accordingly, to achieve a continuously optimal combustion cycle.

• 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.

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.

• 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.
