Exhaust Fault of Mitsubishi Wing Shen Variable Valve System

1. The owner can try to restart the vehicle three times, or unplug the negative electrode of the engine battery, wait for half a minute, and then see if the engine exhaust fault is eliminated. If it is eliminated, it means that it is a false fault and the owner does not need to worry too much.

2. The failure of engine exhaust is mostly due to the problem of three-way catalyst or the damage of oxygen sensor. The owner needs to drive the vehicle to the repair department for maintenance in time, and replace the parts in time if they are damaged.

3. If the vehicle can't start normally at the same time of engine exhaust failure, there may be a problem with the fuel pump or ignition system, so the owner can only drag the vehicle to the maintenance department for maintenance. If the vehicle is forcibly started, it may cause engine damage and increase unnecessary economic losses.
