Car Coolant Temperature Sensor Repair Cost in UAE 2026
The coolant temperature sensor (ECT sensor) is a small but critical component that monitors engine coolant temperature and reports to the engine control unit and the dashboard gauge. In the UAE, where engine coolant operates at elevated temperatures due to ambient heat and heavy air conditioning loads, a faulty coolant temperature sensor can mask overheating or cause the engine to run rich unnecessarily. This guide covers all coolant temperature sensor repair and replacement costs in UAE workshops in 2026.
Symptoms of a Faulty Coolant Temperature Sensor in UAE
The most common symptoms of a faulty ECT sensor in UAE vehicles include a temperature gauge that reads cold all the time or reads hot immediately at engine startup, a check engine light with OBD codes P0115 to P0118, poor fuel economy caused by the ECU running a permanently rich mixture, and rough idle or hard cold starts. A sensor that reads consistently cold tricks the ECU into delivering excess fuel even at normal UAE operating temperatures, wasting petrol at UAE fuel prices.
Coolant Temperature Sensor Replacement Cost UAE 2026
Coolant temperature sensor replacement costs AED 100 to AED 500 in the UAE including parts and labour. Japanese and Korean vehicles, including Toyota, Nissan, Hyundai, and Kia, cost AED 100 to AED 250 for sensor and installation. European vehicles including BMW, Mercedes-Benz, Audi, and Volkswagen cost AED 200 to AED 500 due to higher parts costs and additional labour for access in some engine configurations. American trucks and SUVs cost AED 150 to AED 350. Coolant top-up after sensor replacement costs AED 20 to AED 80 extra.
OBD Diagnosis Cost Before Sensor Replacement
Before replacing a coolant temperature sensor, a UAE workshop should perform an OBD2 scan to confirm the specific fault code and check for additional related faults. OBD diagnosis costs AED 50 to AED 150 at most UAE workshops. Some workshops include the diagnostic fee in the repair cost if work is proceeded with. Confirming the fault code prevents unnecessary parts replacement.
