I have a 95 Tracker as well and recently it turned 100,000 miles. At 100,001 the "check engine light" came on. A local mechanic did a diagnostic and it also didn't give any codes to help reset the light or alert me of a problem. I asked him about the reset "switch" under the dash and he said he never heard of that. I investigated on my own when I got home, because the light being on was driving me crazy, and there actually is a small switch that reset the light. I removed the small plastic panel under the steering column and found it between the drivers side speaker and the steering column. It is really small. It is a black plastic switch with a metal face plate. You really have to look for it because it's settled in with the wire harness' under the dash. I flipped the switch and the light went out. Again be patient when looking for the switch. It's there you just have to look close to the dash and next to the steering column. I tried removing the battery cables because I read that that would reset the light but had no luck doing it no matter how long I left them off.
If you go to AutoZone .com and check with there repair manuals on-line you can find the engine codes for your tracker
There are literally hundreds of diagnostic codes that would cause the check engine light to come on. Many auto parts stores will check the codes for free and tell you what is needed to fix it.
how to reset check engine light on 1992 Mazda mpv
After replacing the EGR valve, use the diagnostic tool and erase codes then read the codes again. I had the same problem on my 97 geo metro. After replacing the egr valve, the check engine light stayed on. After a while it was suppose to clear itself but it didn't. So I went to autozone borrowed their diagnostic tool, erased the codes and then my car passed and the check engine light went off.

It is the port, where a diagnostic machine can be hooked up. The diagnostic will read codes from your vehicles computer. For instance if your check engine light comes on, you can plug the diagnostic machine into the data port and it will tell you why the check engine light came on so that you can get it fixed.
When the light comes on it's telling you to read the engine diagnostic codes.
First you remove the cover from the diagnostic port under the driver's side of the dashboard. Then you plug the datalink cable from your scan tool into the diagnostic port. The scan tool will then show the diagnostic codes. Write them down and read a manual to see what has gone wrong.
The most common engine check engine light codes would be indicating that something has gone wrong under the bonnet basically. Each manufacturer has different codes and so the garage uses diagnostic computer tools to find out the problem.
Without having it checked for codes, It is impossibe to answer.
Diagnostic codes are generated by your on-board computer. They tell you what problems the computer has identified with your engine. The codes are numbers. The code numbers are read by an instrument that plugs into a special jack under the dash. Auto parts stores often will check your diagnostic codes for free, or you can have your dealer do it.
you can either purchase a computer programmer ($200-$350+) that will allow you to check and clear codes as well as adjust computer settings for maximum performance or take the vehicle to most auto parts stores that can check the codes for free.
take it to a dealer or a qualified mechanic for a diagnostic
1995 and later model vehicles need an OBDII scanner to retrieve the diagnostic codes. AutoZone and other parts stores usually will scan free of charge if the check engine light is on.

When the Check Engine Light (CEL) comes on, it means something wrong was detected, either with emissions or performance. When this happens, the computer will have a diagnostic code in memory that can be retrieved with an OBDII scanner. Auto Zone will scan and retrieve the diagnostic codes free of charge.
To tell you to read the diagnostic codes.
with a scan tool. go to a repair shop and they will have one or go to auto-zone an they can read the codes but they cant erase them like a shop can.
Go to AutoZone. They do it for free.
For one, the check engine light will come on. At that point, you'd have a shop hook up a diagnostic scan tool and decipher the codes.

U check the codez
The check engine light came on for a reason. You need to have the codes read to help determine why the light came on. Once the problem is fixed you can clear the codes with a diagnostic scanning device and the light will go away. Your local auto parts store can help you with this situation.
The computer turns on the check engine light in hopes that you'll check the engine codes. It means something is wrong. Use an engine diagnostic scanner to find out what it is. It's easy to do and you can usually borrow one from your local auto parts retailer, they'll often help you figure out what it all means.
