What to Do When the Exhaust System Warning Light Comes On in a Magotan?

[McMiles]

Solutions for the Magotan's exhaust system warning light coming on are as follows: 1. First, check the front and rear oxygen sensors. If they are damaged, the initial symptom will be the engine exhaust system warning light staying on (or occasionally flashing) on the dashboard, but the vehicle may still be drivable for a short period. 2. If not repaired for a long time, the Electronic Control Unit (ECU) of the electronic fuel injection system will not receive information about the oxygen concentration in the exhaust pipe, thus unable to perform feedback control on the air-fuel ratio. This will increase engine fuel consumption and exhaust pollution, and cause engine issues such as unstable idling, misfires, and surging. Therefore, it is necessary to promptly address the fault or replace the faulty parts. 3. Generally, modern vehicles are equipped with two oxygen sensors, located before and after the three-way catalytic converter. It is important to identify and replace the faulty sensor in a timely manner.
