I have a 9o xj 4.0 need a mat sensor. told it was obselete from jeep. the 1 I have has wires made to sensor, the replacements I've found have no wires. The ones I've seen look like the 1 on my 94 4.0 & I've checked them & the resistance values are different. HELP please

i have a '90 parts jeep. send a pic of where it is a I will send it to you usps

5-90

Look for a brass hex bung with two wires coming off of it, I believe it's forward of the throttle body.

OP - Except for the TPS and HEGO, all of the sensors and such on RENIX are GM parts. I've gotten them from Marren Fuel Injection (www.injector.com, I think) fairly cheaply in the past. You'll have to reterminate the IAT wiring to fit their sensor - but you can cut the tail off of the old one and use that to make an adapter tail (so you can go back and forth as needed.)

thanks for the help. don't have a pic of sensor but it is on the back of the intake near the firewall.

Oh - wrong end. Sowwies!

Kinda makes some small sense to have it back there tho - that would be the hot end of the intake (although it would make the front cylinders run a shade lean, but that should be corrected by the feedback from the HEGO sensor...)
