Car Coolant Temperature Sensor Replacement Cost in UAE (2026)
The coolant temperature sensor (CTS) tells the engine ECU how hot the engine is. A faulty sensor causes overheating warnings, poor fuel economy, hard starting, and emission failures. Here is what UAE drivers should expect to pay in 2026.
Coolant Temperature Sensor Replacement Costs
| Vehicle Type | Estimated Cost (AED) |
|---|---|
| Japanese / Korean vehicles | 120 – 350 |
| European vehicles | 250 – 700 |
| American vehicles | 180 – 500 |
| Luxury / Premium brands | 400 – 1,200 |
The sensor itself is usually inexpensive. Most of the cost is labour and any coolant top-up needed after repair. Some vehicles have multiple temperature sensors which can affect pricing.
How the Coolant Temperature Sensor Works
The sensor uses a thermistor that changes electrical resistance as coolant temperature changes. The ECU reads this resistance to determine engine temperature and adjusts fuel injection and ignition timing accordingly. In UAE summer conditions (up to 50C ambient), engines run hot and these sensors degrade faster than in cooler climates.
Signs of a Faulty Coolant Temperature Sensor
Common indicators include an overheating warning when the engine is at normal temperature, the temperature gauge reading cold after warm-up, poor fuel economy, rough idling, black exhaust smoke, and a check engine light with codes P0115 through P0119. The car may also run rich because the ECU thinks the engine is always cold.
