A green light skows indicating "service engine soon"

bring the car to a local mechanic and have them look over the car as the "service engine soon" light can mean a verity of different things need to be checked, replaced, and sometimes it is as simple as having the computer reset. There really is no way to determine what the problem is or if there is even a problem just by looking at the light.

Noticed that warning light on my dashboard is showing service Engine soon confirmed that it is my speed sensor is faulty. how many sensors are on the vehicle and want to replace them.

This is a new one the engine service light is on and its caused by teh speed sensor?? this is a totally new fault showing and iam wondering how you learnt the speed sensor is the cause ,unfortunatly their is no listing for resetting a mitsubishi service light in my alldata book so it looks like its a dealer only job although i bet its possible on this older vehicle somehow ,like holding the trip meter on and then turning the ignition on or the AM/fm button the radio or something equally bizarre

Service engine soon light went on on my mitsubishi montero sport 2000

you can take it to any autozone or advanced auto to get the light scanned but before you purchase whatever sensor they tell you to get, find a good mechanic that can give a second opinion. Often a sensor can be thrown off by another faulty sensor that may not come up during scan.
