    The check engine light in my 2011 Mitsubishi Pajero won't turn off

    Mitsubishi Mitsubishi Advice Mitsubishi Pajero Mitsubishi Pajero Advice Mitsubishi Pajero 2011

    I have the check-engine light on in my 2011 Mitsubishi Pajero Platinum and have replaced everything electrical to do with the EGR system but the light won't go off. What are the possible causes and how do I fix it?

    There are literally dozens of reasons the check-engine light might illuminate in a car like the Pajero. Fundamentally, the car is trying to tell you something is not right with one or more of its systems, and that it needs attention. Those systems could include (but are not limited to) the ignition, fuel, emissions, exhaust, mechanical and cooling systems.

    Simply replacing random parts is a quick way to burn up a lot of money and still not fix the problem. I’m curious as to why you’ve assumed the problem is with the EGR system. And even if you’re right and the EGR system is causing the problem, you might find the fault is with the actual EGR valve or its coolant system, rather than the electronics that control and monitor it.

    Take the car to a workshop and have it electronically scanned to try to narrow down the cause of the check-engine light. The fault codes will have been logged by the on-board computer and are usually the only way to zero in on the actual problem. Even once that’s done and the problem fixed, there’s probably a separate procedure for switching the engine light off.
