How to Defeat the Engine Check Light after Performing ANY EGR Mod

We apologize for the missing images, this article was missing for some time and brought back thanks to Archive.Org, unfortunately, some images could not be recovered

Purpose: To prevent check engine light from turning on after performing any egr mod.
Parts Required: 10K Ohm 1/2 watt resistor, Available at Radio Shack (Part #271-1126), Electrical tape.
Time Required: 3 minutes.


  • Unplug the EGR gas temperature probe electrical connector pictured below. Insert a 10K ohm 1/2 watt resistor into the connector (fig. 3). This prevents a CPU trouble code from being tripped. Tape the connector with electrical tape to prevent the resistor from falling out.

Note: it is hard to see the electrical connector on 97-98 models because it's located in the opposite position of 93-96, its between the manifold and engine valve cover towards the back (firewall) - look for it using a flashlight. A screwdriver will help you unplug the harness.
