Question about 1988 Mitsubishi Mighty Max
HI. There may be a stored code loaded om the engine computer. The correct way to shut of the check engine light(maintenance required light), will be to initiate the off mode with a proper diagnostic scan tool. If it continues to remain illuminated after you have properly shut it down, via scan tool, this will indicate that there are more issues that should be inspected on this particular engine. Perhaps the PCV(Positive Crankcase Vitalization) valve boot is kinked or has collapsed. The O2 sensor may not be connected well, or inserted improperly.
In most cases of this nature, there is simply another code present that will need ot be pulled by a certified diagnostic scan tool. We call these codes (Stored DTC).

Removal & Installation
WARNING When disconnecting the sensor electrical connector, do not pull directly on wire going into sensor.
NOTE Allow the O2 Sensor to cool down before conducting the test. The O2 Sensor voltage should stabilize at 5.0 volts. Raising the hood may help in reducing under hood temps quicker.
