Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you will need to have the car diagnosed and repaired.

The check engine light is the cpu telling you that there is a fault in the parameters of the sensors it continually monitors. Have a fault code reading done and replace the faulty sensors

I have a 2002 4runner and the engine light plus trac off/vsc trac light is on. Do you know what the problem is?


You need to have it scanned to find out why the Check engine light is on. Autozone will do this for free. As for the other two lights, don't worry about them. They are just on because of the check engine light. They will go off when the engine code is cleared.

1998 toyota 4runner reset check engine light


Hi. You can reset the check engine light by removing the blue 15 amp EFI fuse (fuse box under the hood). If you do this, and the check engine light is illuminated again, you will need to address the cause for the light to be on; you have a 'hard fault'; and a part may need replaced.

Where do I find the sensors to replace them? I need a diagram.


It is located on the exhaust pipe. One on each bank normally front and rear. If you go to autozone, they will do a free diagnostic and let you know exactly which one is bad. They are easy to get to and replace, you just need to know which one is bad.
