Hey guys, need some help here.... I just got a 1997 eclipse in great condition I thought. Two weeks after I got it, I had to take it to the shop cause it was stock in like 2nd gear after about 30min in the highway. It did run fine in the city but just not in the highway. Anyways, the guy told me it's was in "Limp mode" and the speed sensor needed to be replaced among with some "leaks". Unfortunally, that was $700. It's been 3 weeks and the problem came back two nights ago, took it to the same place and they just called me saying I need a Tcu Trans module. That I can only get that from the Mitsubishi dealership and it will run$400.. plus all their little extras is gonna be another $700. Don't have that type of $$$ to be handing out... and don't know to much about cars, so just need some advice for what or if this makes since to you experts!!

 

Kinda hard to diagnose the problem, but it does seem that it may have just been the TCU and not the speed sensor. For a bit more clarification, What model do you have and how many miles on it?

 

It's a 1997 Mitsubishi Eclipse Rs Non turbo with 92300

 

Thank God for Junk yards.... I had to take care of these problem myself, can't trust anyone it seems like now days.. Anyways, I got a TCM and installed it myself...I'M SO PROUD OF THAT! The car seems to have more power but the check engine is still on. I don't know if I need to get it restart or reprogram or something. Do you guys by any chance know what I can do. Thanks

 

just reset the computer, unhook the battery cables for about 15 min, hook it back up and let the car run for about 15-20 min so the computer can relearn with the "new" TCM and it should clear out the SES light.........

 

Thanks all is done N CEL IS GONE BYE BYE!!!!
Cheap is good but free is better!!!!!!!!!!!!!!!!!!!!!!

 

I Recently bought a 1998 Eclipse Rs. and the engine compartment was disgusting so i pressure washed it. well about an hour after i pressure washed it the Check engine light came on.
Took it to Autozone and the code came up saying it needed a output speed sensor. Took it to midas and had it replaced. they reset the code and it almost immediately came back on. still in limp mode. WHAT COULD IT BE?
