Car Crankshaft Position Sensor Replacement Cost UAE (2026)
The crankshaft position sensor (CKP sensor) monitors the rotational position and speed of the crankshaft and sends this data to the ECU for fuel injection timing and ignition timing calculations. A failed crankshaft position sensor is one of the most common causes of a no-start condition on UAE vehicles — without a CKP signal, the ECU cannot time the fuel injection and ignition events, and the engine will not run. The sensor can also fail intermittently, causing the engine to stall without warning — a dangerous fault on UAE motorways. UAE heat cycling and the vibration environment on the engine block accelerate CKP sensor failure.
Crankshaft Position Sensor Costs in UAE (2026)
| Service | Cost (AED) |
|---|---|
| CKP sensor (aftermarket) | 60-200 |
| CKP sensor (OEM) | 150-500 |
| Labour (easy access position) | 60-100 |
| Labour (difficult access) | 150-300 |
| Diagnostic scan to confirm fault code | 80-150 |
CKP Sensor Diagnosis in UAE
UAE garage CKP sensor diagnosis involves reading the fault codes (P0335-P0338 range for crankshaft sensor circuit faults) and checking live data for the CKP signal on a scan tool. A scope test of the sensor output waveform identifies whether the sensor is producing a clean signal or has intermittent dropout. Wiring damage — particularly at the connector which can corrode in UAE humidity — is also a common cause of CKP circuit faults. The sensor itself is a relatively inexpensive part but must produce a precise signal for the engine to run. Always confirm the fault code before replacement.
