i changed the part but nothing.
If you could kindly assist me, on a fix..
It sounds like the wiring to the sensor is a faulty circuit. The wiring between the sensor and the Engine Control Unit, (ECU), requires inspection for continuity, shorts to ground, and correct input and output voltages. Once it is confirmed which of these circuits is faulty, it is a good idea to start looking where the main engine wiring loom leaves the engine and is attatched to the vehicle body, the area where the loom flexes when the engine 'moves' is more likely to be the place to find the faulty wiring/circuit.
