Haval m6 throttle signal is not credible.

The signal of Haval m6 throttle position sensor may fail because the circuit voltage is too low, giving people a sense of failure.

The fault of the throttle position sensor signal may be due to the low circuit voltage signal, and the inspection method is as follows:

1. Measure the position signal voltage with a multimeter, find two position signals, and check whether the measured voltage value and change relationship are correct. If they are all correct, the ECU on the engine electronic control unit may be broken. Try a new one.

2. If one of the two position signals is incorrect, cut off the signal wire from the harness, and then measure whether the signal voltage at the throttle end is correct. If it is not correct, the throttle is broken; If the signal is correct after disconnection, the ECU is damaged.

3. If the two position signals do not conform to the above-mentioned change law, check whether the 5V power supply voltage is correct and whether the grounding wire is grounded.
