service engine soon

[1994GeoTracker]

Thanks,
Reading your email helped me a lot. I have a 1994 GEO tracker that just turned 170,000 miles too. And, my light came on. I found my “MALFUNCTION INDICATOR LAMP (MIL) CANCEL SWITCH” (Check Engine switch) directly behind the drivers-side speaker. Two ways to get to the switch: Remove the removable panel just below the steering column on the dash board. Next, get in a position to see the rear of the speaker and there it is!….. It’s right next to it (speaker magnet) just in index-finger range….. The second option is to remove the speaker cover, and speaker. Then simply reach around where the speaker WAS and there it is (the switch). Mine was a sliding switch. I simply slid the switch over. And, now my “check engine lamp” no longer stays on after engine is running. Thanks again, Scott

Just bought a 1995 4x4 LSI, with an automatic that has just over 100k on it, the Check engine light is on. After looking thru this forum I determined that:

1 - I needed a repair manual, so I bought a Haynes Repair Manual for the 86-01 Suzuki that includes Geo Trackers, this is the only manual I could find at Autozone.

2 - Locate the reset switch.

So the problems I have are; I found the switch but what is the correct procedure to reset, do I leave the ignition off and slide it, or have the ignition in the on position before I slide it? Do I need to move the switch back to the original position or does it stay in the new position - I had hoped my manual would explain it but it does not even mention the switch.

As far as pulling the codes the manual says to "Obtain the codes on 1991 through 1995 Sidekick and Tracker models by using a jumper wire between the 2 and 3 terminals of the test connector located next to the battery." It shows a picture of a 4 pronged plug in and lists the teminals:

1 2
3 4

1 Duty check terminal
2 Diagnostic test terminal
3 Ground terminal
4 Test switch terminal


What I found under my hood is a six prong plug with 5 wires:

1 2 3
4 5 6

1 Has no wire
2 Blue with Yellow stripe
3 Purple with Yellow stripe
4 Black
5 Blue with Red stripe
6 Purple

So if anyone can help me determine the procedure for pulling codes I sure would appriciate it.

Thanks for any help.

leave the key off and slide it to the new position and leave it there , the plug your looking for is over by the battery near the main fuse block , it's there but it might be hidden under some other wiring , it took me a couple of mins to find it my self

Thanks for the quick responce, I tried the switch and the light stays on so I must have a trouble code in the memory. I have looked and relooked around the battery and cannot find any 4 prong connectors that are not allready attached to a relay of some sort, so I took a picture and put it on a web site at: http://home.stx.rr.com/hesszoo/tracker if you could please take a look and maybe let me know what I'm missing I sure would apprciate it.

i would say number 4 was it but you said that has 6 wires , let me take a look at mine when i get home this afternoon from work , i will get back to you as soon as i can

[hesszoo]

You are correct it is number 4 and it is a six hole plug. I stopped at the Library and checked a Chiltons that showed the 6 prong for a 1996, it is called a Duty Check Data Link Connector (DC-DLC) and the wires are:

1 2 3
4 5 6

1 - Has no wire
2 - Diagnostice Request Terminal, Blue with Yellow stripe
3 - Diagnostic Output Terminal, Purple with Yellow stripe
4 - Ground Terminal, Black
5 - Test Switch terminal, Blue with Red stripe
6 - Duty check terminal, Purple

I jumped terminal 2 with terminal 4 and got my codes, I had 2, a 13 O2 sensor, and 51 EGR. Iwill test them tomorrow and then change what I must.

I just wanted to say thanks for trying, and also let others know what I found.

glad you got if figured out , i was thinking that your might have the 96 system on it when i was looking at mine today , just goes to show that you learn something new every day , if you need any parts for a tracker let me know , mine has a blown engine and i am not going to fix it , it has a brand new top , was only on the car for a month and 8 month old tires with only about 10,000 miles on them

On mine the O2 sensor was fine it was showing up as a fault because the EGR system was malfunctioning (Code 51). Luckly my book, Haynes Repair Manual, told me to check/fix all the other codes before worring about the O2 (Code 13).

1. First check was all vacuum hoses for cracks or breakage.

2. Check the EGR by running the engine and slowly lifting the Diaphragm on the EGR - which should cause it to run rough or stall. I also checked it with a vacuum pump.

3. Next I checked the EGR modulator, following the procedures in my book.

4. The last thing I checked goes by about 3 different names, Bi-metal Vacuum Switching Valve (BVSV), Three-way Solenoid Valve (TWSV), or Vacuum Switching Valve (VSV). Turns out mine was a bad VSV, which if you have to buy it I recommend going to the Suziki dealor as the Chevy dealer wanted $90 for it and Suziki sold it to me for $60. Both dealors were going to make me wait a week to receive it.

After replacing the VSV, I cleared the codes and have not had a recurrance in the last 3 weeks. Good luck

No one can figure out how to solve this problem! I'm driving around with expired out-of-state plates because I can't get it to pass an emissions test.

After replacing the O2 Sensor and running a cleaning through the EGR "system" the light still won't go off.

Went to the Chevy Dealer and they say that there is an open in the solonoid circuit and the PCM is not grounding ground side of EGR Solonoid.

They want to put in a new PCM that is more than what I purchased the car for!

My trusty hometown mechanic is looking for a remanu. PCM. Is there any other way to get this thing to pass emissions with out spending so much money!!
