15 brand-new yinglang suddenly lost power. What happened to the engine fault light?

The fault indicator light of Buick Hideo engine in Pacific Auto Network is on. When the ignition switch is in the "on" position, it is normal for the engine fault indicator to light up. When the engine is running, it indicates that the emission control system is faulty. May exceed the allowable emission limit. Indicates a fault that may cause damage to the catalytic converter. Please reduce the pressure on the accelerator pedal until the indicator light stops flashing.

Because the throttle position sensor 1 and 2*** use the same power supply and grounding, when the vehicle is abnormal (the "burr" phenomenon of the throttle position sensor position signal 1 and 2), it does not appear at the same time, which basically shows that it has nothing to do with the power supply and grounding.

The signals of the two sensors are fed back to ECM independently for processing. If there is an internal fault in ECM, it is unlikely that both signals will be reported wrong and damaged at the same time, so the probability of judging the internal problem of throttle valve is the highest.

It should be noted that in order to reduce or avoid possible damage to the engine control system when the lights are on, the driving speed should not exceed 70km/h, so as to avoid sudden acceleration or sudden braking, driving on steep slopes, and loading or towing unnecessary loads.

If the engine oil pressure light comes on: engine lubrication may be interrupted. This may result in engine damage and/or locked drive wheels. The following operations should be performed: Press the clutch pedal (manual transmission). Select neutral and set the shift lever to N position. Leave the traffic as soon as possible without affecting other vehicles. Then turn off the ignition switch.
