Camshaft Sensor Replacement Cost in UAE

The camshaft position sensor (CMP sensor) is a critical engine management component that works with the crankshaft sensor to provide precise valve timing data to the engine control unit. A failing camshaft sensor causes rough running, misfires, and poor performance. This guide explains what camshaft sensor replacement costs at UAE garages and how to identify a fault.

How the Camshaft Position Sensor Works

The camshaft position sensor reads a reluctor ring or target wheel on the camshaft to determine exact camshaft position. This data is sent to the ECU which uses it to control sequential fuel injection timing, ignition timing, and variable valve timing (VVT) systems. Vehicles with variable valve timing are particularly sensitive to camshaft sensor data accuracy, as the VVT system continuously adjusts camshaft timing for optimal performance and fuel economy.

Camshaft Sensor Replacement Cost by Vehicle Type

Single camshaft CMP sensor replacement costs AED 150 to AED 500 at UAE garages including diagnostic scanning, parts, and labour. Toyota, Nissan, Honda, Kia, and Hyundai CMP sensors are widely available in the UAE aftermarket and cost less to replace. BMW, Mercedes-Benz, Audi, Volkswagen, and Jaguar Land Rover sensors cost more due to higher OEM parts prices and in some cases more complex installation locations.

DOHC engines (dual overhead camshaft) typically have two CMP sensors, one per camshaft bank. If both sensors fail or both are showing fault codes, the replacement cost doubles. However, it is common for only one sensor to fail at a time.

Diagnostic Scanning Cost

Before replacing the sensor a UAE garage will scan the ECU for fault codes. CMP sensor fault codes are typically P0340 through P0349 depending on which camshaft and which bank is affected. Diagnostic scanning costs AED 50 to AED 150 at most UAE garages. Some garages offer free scanning when the repair is carried out at their workshop.
