The geo trackers have a switch behind the speaker under the dash that's a toggle switch.. It is scheduled to come on at 80,000 miles just as a check up.. Take off the cover to the speaker and you will find a toggle switch in there jsut switch it over and walla the light is off!!

The 80K sensor light means the oxygen sensor needs to be changed out.

It was helpful learning about the cancel switch under the dash. I didn't even need to take off the speaker cover. I just popped out the panel under the steering column and it was right there! Last time, it cost me $70 to get that thing turned off. This time it cost me 5 minutes of time. Love that.

The 80K light switch is not always true. It could come on any time. Mine came on at 50K and my car is running just fine. It may not be the switch under the speaker cover or under the steering wheel cover, it could just be the wiring. That is what happened to my vehicle.

This just happened to me. I have a 1993 Geo Tracker. I noticed this "Check Engine" light at 80,001. I just got off the phone with the Chevy/Geo dealer; I had asked if the Check Engine light came on at any certain mileage. He insisted that no, it did not, and that I should have my car looked at right away (at a cost of $65). I just found came across this web site through Yahoo (searched on Tracker Check Engine 80000) and saw that indeed this Check Engine light comes on at 80,000. My husband popped off the speaker cover, hit the toggle switch, and all is well. I am so happy to have found this web site!!! Thanks for writing of your experience!

I have a 1995 Geo tracker The Check Engine light comes on in every Geo tracker after 80,000 miles.

I have a 1995 Geo Tracker what does the switch look like to turn the check engine light off? Is it a toggle switch or a push button switch? I took speaker on drivers side out and did not notice a switch? Thanks.

My 95 has 156000 K's and the light has not come on. It runs great and have had no problems. Has everyone had their steering checked as there was a recall. Just take your serial # to a GM dealer and have it checked for any outstanding recall notices that have not been done.

The check engine light on my '94 Tracker went on at 50,000 miles, 80,000 miles, and 100,000 miles. The first two times I paid to get it reset. The third time I tried using the switch behind the left speaker to reset it, but that didn't work, so I have given up on turning it off. Car now has 184,000 miles and is still going fine.

Thanks... stinkfinger6.

I have a 91 tracker with the check engine light on. I looked several times behind both speakers and cannot find that switch. Was the older tracker differant? What should I do?

26th Jun 2008, 20:55

I too have a 1991 Tracker and cannot find the reset switch behind the left speaker or behind the pop-off plastic panel under the steering wheel. HELP!!

The check engine light on my 1995 Tracker came on at 100000. The switch on mine is behind the left speaker at the right side of the opening, and the switch is on the far side of the little block screwed to the dash from the inside. The engine seemed to have to be running before switching. Now all is well.

I just purchased a 1998 Geo Tracker and it has this CEL Light on. Can I have a detailed description on how to reach this hidden light so I may reset my Tracker light?

Thank you!!!

Geo engines are non interference engines. If the belt breaks it won't wreck the engine, and on the 89 to 95 Trackers the switch is right by the drivers side front speaker; it's hard to see, but it's there.

Thank you all, especially for the "check engine" light comments. I recently passed NJ inspection with the red light on... I was amazed, and the technician told me that I wasn't emitting anything bad, therefore I passed!. The red light is still on, and I will try to find the speaker cover switch tomorrow. My question now is "how do I remove the panels that hold the speakers if I want to put a new set in"? My '95 Geo is in excellent condition with just 56k miles that I have as a second car.. it's great in the snow too! Can anyone help me please?? I don't want to damage this beauty...

Thank you

I just bought a 95 Tracker from a friend. He said the check engine light had been on since the family owned it. The car would hesitate bad when cold, and maybe get better warmer. Since I changed the switch, I can check engine codes, which there are none, and the car runs a lot better. Go figure.

I have a 95 Geo Tracker, it has turned 100,000 miles.

I have had the car for 11 years.

Problem: The engine 90% of the time runs perfectly!!

However on occasion, the engine will run rough on take off, and about 2200 rpms, almost as if it is not getting enough fuel.

All the usual suspects have been addressed, no change.

Engine is 16 valve, and I use high test and injector cleaner regularly. This is a OCCASIONAL problem, not all the time.

Anyone have any clues to why???

Sincerely... Bob.

The "slider" (not toggle, in my estimation) switch is where it's said to be, behind the left front speaker on the right-hand side of the speaker "hole" (cut-out).

However, you have to first remove the two screws that hold the speaker grille in place, then remove the two screws that secure the speaker to the plastic panel to gain access to the switch, which is mounted on a metal plate; I had to rotate this plate slightly to get to the switch.

All that being said, it did not make the "Check Engine" light go out, no matter whether I slid it to the left (or "new") position, nor whether I slid it back the the right (or "original") position. It should also be noted that this is after I just installed an expensive ($85.00) new oxygen sensor (which solved the problem the last time, and which I "assumed" would fix the problem this time - obviously it didn't).

My car is a 1995 Geo Tracker LSI with the 1.6 Liter, 16-valve engine in it with 4WD. If anybody has any additional ideas, I'd be happy to hear them.

I have a 1995 Geo Tracker. The check engine light came on around 70,001 miles. I read the comments about the switch and decided to try it. I found it without too much effort. I "slide" the switch to the left, and the check engine light went off. It has never came on again. But my question for all of you is : Do I leave the switch to the left side or do I switch it back to the right?
