Car Throttle Position Sensor Replacement Cost UAE (2026)
The throttle position sensor (TPS) monitors the position and movement of the throttle plate and sends this data to the engine control unit (ECU). The ECU uses this information to calculate fuel injection quantity and ignition timing. A faulty TPS in UAE vehicles causes erratic acceleration response, rough idle, hesitation on acceleration, and in some cases engine stalling. UAE vehicles with a faulty TPS often exhibit jerky or inconsistent throttle response — particularly noticeable in UAE stop-start traffic where smooth throttle control is important for safe driving.
TPS Replacement Costs in UAE (2026)
| Service | Cost (AED) |
|---|---|
| TPS sensor (aftermarket) | 40-150 |
| TPS sensor (OEM) | 100-400 |
| Labour (TPS replacement) | 50-100 |
| ECU relearn procedure after replacement | 50-100 |
| Full throttle body service including TPS | 150-400 |
TPS Diagnosis in UAE
UAE garage TPS diagnosis involves reading the live TPS voltage data with a scan tool while the throttle is slowly opened from closed to fully open. A healthy TPS produces a smooth, linear voltage increase from approximately 0.5V (closed throttle) to 4.5V (full throttle). A faulty TPS shows voltage spikes, flat spots, or erratic readings. The fault code P0120-P0124 (TPS circuit) confirms the fault. After replacement, most vehicles require an ECU throttle relearn procedure (idle relearn) to calibrate the new sensor position.
