Chery to accelerate engine dysfunctional failure Result in Alternative

Failure phenomenon auto diagnostic tool: all through acceleration, the engine pace may well not be a corresponding improve, but dysfunctional, even flameout. The vehicle had cleaned the throttle body, change the spark plug failure remains.

Verify examination: the transfer of fault code display: 1, No. 34 and 35 in the engine ECU wiring disconnect. 2, battery failure. Learned through the circuit diagram, 34, as the key engine ECU ground wire, No. 35 for the engine ECU 12V electrical power input, it can be on the preliminary see that the engine the ECU provide lines exist poor get in touch with. So initially check the 34 main ground wire, electrical power provide fuse and also the engine ECU key relay No. 35, and found that the the shaking engine ECU key relay can occasionally Launch hear the sound of its contacts open. Then open the ECU principal relay uncovered its indicators of damp, make contact with ablation. Exchange the primary relay after the check, have improved relatively but nonetheless accelerate sluggish. Get fault code has no output, and each sensor injector is operating, but located that the fuel pressure inside the fault seems far reduced than the typical pressure, it can be concluded the difficulty together with the fuel supply method. Test the fuel filter, strain regulator fuel pump, fuel pump pace fluctuations fault seems, the fuel pump isn't operating properly, may be because of the fuel pump itself may well fuel pump line fault. Verify the fuel pump supply line, fuel pump relay output voltage instability, then unplug the relay and open to inspection located its coil moist, get in touch with ablation.

Troubleshooting: change the fuel pump relay following the test, the engine is operating back to ordinary.

Overview Summary: PDI Launch X431 GX3 consumer reflect prolonged in the past had cleaned the engine, clean the engine and bring about the engine ECU major relay and fuel pump relay internal moisture injury, which suggests that owners not use water to clean the engine.
