Throttle Position Sensor Replacement Cost in UAE
The throttle position sensor (TPS) tells the engine control unit exactly how far the throttle plate is open at any moment. A faulty TPS causes hesitation on acceleration, unstable idling, and poor fuel economy. This guide explains what throttle position sensor replacement costs at UAE garages and how to identify a TPS fault.
How the Throttle Position Sensor Works
In older cable-throttle vehicles, the TPS is a simple potentiometer mounted on the throttle body that changes resistance as the throttle plate rotates. In modern drive-by-wire vehicles, the TPS is part of an electronic throttle control system and may include dual sensors for redundancy. The ECU monitors TPS voltage and calculates the corresponding throttle opening percentage. A TPS that sends incorrect or erratic readings causes the ECU to apply the wrong amount of fuel for the given throttle position.
TPS Replacement Cost at UAE Garages
Throttle position sensor replacement for cable-throttle vehicles costs AED 150 to AED 400 at UAE garages including the sensor and labour. The sensor itself for common Asian vehicles costs AED 50 to AED 200. For drive-by-wire vehicles where the TPS is integrated into the electronic throttle body assembly and not sold separately, the entire throttle body must be replaced, costing AED 400 to AED 1,500 depending on the vehicle make and whether an OEM or aftermarket part is used.
Throttle Body Cleaning vs TPS Replacement
Carbon deposits in the throttle body can cause symptoms identical to a faulty TPS including rough idle and hesitation. UAE dust and stop-and-go traffic conditions accelerate throttle body contamination. Before replacing the TPS sensor, most certified UAE garages will clean the throttle body first and reset the throttle position if equipped with electronic learning capability. If cleaning resolves the symptoms the sensor itself is fine. If symptoms persist and fault codes remain, sensor or throttle body replacement is required.
