Crankshaft position sensor (Chevrolet Orlando 1)

The crankshaft position sensor is designed to generate signals by which the electronic control unit (ECU) synchronizes its operation with the engine's operating cycles. That is why this sensor is often called a synchronization sensor. The sensor operates on the principle of induction: when the teeth of the drive disk pass the end of the sensor, voltage pulses are generated in the sensor circuit. The frequency of pulses corresponds to the rotation frequency of the engine crankshaft.

The sensor is installed on the rear wall of the cylinder block near the gearbox housing.

Engine operation with a faulty crankshaft position sensor is impossible. The crankshaft position sensor cannot be repaired; in case of malfunction, it is replaced as an assembly. If the sensor is faulty, a sensor fault code is entered into the ECU memory. All fault codes can be read from the unit using a special scanner at a specialized service station.

The need to replace the sensor is determined during diagnostics of the engine management system.

Replacement

1. We prepare the vehicle for maintenance and repair and install it on an inspection pit or overpass.

2. Disconnect the wire from the negative terminal of the battery.

3. In the engine compartment, pressing the lock, disconnect the wiring harness connector from the crankshaft position sensor terminals. We disconnect the sensor block from the bracket.



4. Inspect the connector and make sure there is no corrosion, oxidation or damage. If necessary, treat it with a special agent to clean and protect electrical contacts.



5. Disconnect the sensor wiring harness holder.



6. Remove the starter.

7. Using a 5 mm Allen key, unscrew the mounting bolt and remove the sensor.



8. Install the sensor in reverse order. Tighten the sensor mounting bolt to a torque of 4.5 Nm.
