If the light was flashing when it came on, then it means your engine is misfiring.

A solid light can mean anything from a loose/faulty gas cap to a transmission issue.

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain on. If the light turns off, then it has detected that the issue may no longer be present.

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially turn on.

I have a Mitsubishi 2007 Triton Cab/Chassis vehicle,I would like to shut off the engine management light permanently if possible. It comes on at start and stays on some of the time and then at other times...


Hi Barry,
I'm afraid you may have misunderstood my ad. I do not have any "magic fixes" that will get the light to turn off. I only offer help with performing diagnosis and repair to those who would like to save money. Diagnostic time at a shop is expensive, as you probably already know. The way I can help you is to avoid the diagnostic time at the shop and diagnose the problem yourself and perform the repairs necessary to correct the problem with your engine management system without replacing a bunch of UNNECESSARY parts trying to GUESS what the problem is.

Here is the next problem. I need to know which engine your Triton is equipped with and which fault code numbers you are getting. There is no way to look up the correct diagnostic procedure or wiring diagrams or anything else we may need without this information.

Also, Triton is not sold in the USA. The Triton platform is sold in the USA as a Mitzubishi Raider. I have diagnostic and repair information for the Raider, but none for the Triton. They are probably very similar, but I won't know for sure until we get into diagnosing your truck.....wire colors, component locations, etc., may be a lot different.

If you would like to continue and see if we can get your truck fixed, let me know.

Engine management light is on and driving slugish


The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.

When the Check Engine light (or Service Engine Soon) is turned on, the systems computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible system faults (the gas cap is just one of them) that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen/Oriley and Autozone parts stores (USA only) do this testing for free.

The engine management light coming on could be the result of any number of things/systems that are monitored by your engine computer. EGR valve failures are very rare. (Although many get changed by DIYer's trying to "guess" what may be causing the problem.) Your engine computer will record a fault code to tell you why it has turned this light on. I would recommend having your computer system scanned to find out exactly which system the computer is having a problem with, then properly diagnose that system to locate the actual cause of the failure.

On my Toyota Sienna 2008, my check engine light, Trac Off and VSC lights are one. Why? How do I fix it?


On most Toyota's that are equipped with Cruise Control (Vehicle Speed Control or "VSC") and with Traction Control System (TCS or "Trac") all of these lights will come on at the same time if the Engine Control Module (ECM) determines that there is a fault in the engine management system that 1. Prevents the engine from being properly controlled. 2. Prevents the VSC from being properly controlled 3. Prevents the TCS from being properly controlled 4. Any combination of items 1,2, and 3.
Most of the time it is caused by a single fault in the engine management system. Fault codes are codes that are output by the ECM to let a diagnostician know which of the many systems, that are monitored by the ECM, is malfunctioning. To find out what the actual cause is, you must scan the ECM for fault codes then use this information to begin diagnosis of the system that the fault codes point to.

Nissan primera, engine management light permanently on. When car is first started gearbox changes without a problem. when the engine gets warm it sticks in 1st or sticks in 3rd and 4th and won't change...


Hi Kev,

Your Nissan Primera has an on-board diagnostic computer which can detect malfunctions in either engine or transmission.

When the Engine Management light remains lit, this means some faults are present and need investigating.

From what you've described, one of the issues is indeed related to the transmission, but you will need to have the trouble codes (DTC's) extracted from your vehicle's computer, in order to determine what requires repair.

Whenever power is disconnected (i.e. the battery) and re-connected, this resets your vehicle's computer momentarily, until such time as it detects the fault again.

Recommend you either have your local dealer extract the codes (for a small 15min labor fee), or learn to extract the codes yourself, using a suitable jumper wire.

Go to a parts store and run a free diagnostic test. It will tell you the codes that have popped up and then you can fix it from there. That light means the computer is sensing a problem.
