Top 10 1994 Chevrolet S-10 Questions & Answers

tps sencor or maf sencor

I had a similar problem with my 1994 S-10 LS extended cab. Both tail brake lights worked fine. I removed the 3rd brake light cover and tested for voltage at the steel center of the two rivets and found the positive (driver side) negative (passenger side) were good. I checked the two metal strips that send power to bulbs and found the positive side was open. Seems the flared side of the rivet was not making contact with the metal strip. I bucked the rivet with a punch and hammer and it took care of the problem.

I believe it is on or next to the fuel pump in your tank witch is usually on the top of the tank.

If it broke it should have released itself, the system is a simple cabel pully system, if its broken the cable cant have the tension to keep the brake engadged. if you want to release the handel pull the release and physicaly move the pedal.

Is this your setup? Firing order is 1-3-4-2

Look for the emissions label inside the engine compartment, they usually have the emission routing schematic for your car there. Failing that your local library has access to online service manuals, you can get the info there, free.
