Hey everyone!

I recently bought a '98 XE 4x4.  The check engine light was on, so I had the computer checked at AutoZone.  The computer read a failing EGR system.  After doing some diagnostic with a vacuum pump and a multimeter, I find that both the solenoid and the temperature sensor have failed.  Where I live, there is no emissions check, so I want to just block off the EGR system right now and save the money.  My plan is to replace the temperature sensor with a resistor, then find a new solenoid at a junkyard (since the EVAP vacuum shares this as well).  I plan to get a wiring connector from a junkyard too so I'm not butchering my own wiring when I put in the resistors.

What resistor do I need to block off my EGR and make the ECU happy (no check engine light), and is there anything else I need to be aware of?

Okay, I found the answer to my own problem.  On the AutoZone website I found a chart listing resistances for certain temperatures, unfortunately I am having an error uploading the image.

At 32 degrees (F) the resistance should be .62 - 1.05 M ohm

at 122 degrees the resistance should be .065 - .094 M ohm

at 212 degrees the resistance should be .011 - .015 M ohm

On a different forum, someone with an S14 used a 100 K ohm resistor and blocked off the EGR, which tricks the computer into thinking the intake temperature is just under the 122 degree mark, so I think I will try this.

If anyone is interested in doing to same (it should increase fuel mileage and power a little), I will post pictures and results when I am finished.

Thanks Bro...

In the DFW Texas area they don't sniff late models. They plug the trucks computer to a state computer. My '99 V-6 has always passed every year and the the state loves the $400.00 it cost me!

Friends get ready for this…

In the future all individuals will have to buy carbon credits. These carbon credits will be in the Commodities Futures Market and speculators will be driving the price up to $4.00 per credit!!!
