Thanks for the reply ,I uesing on 00

 

Hmmm...that's strange. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Maybe check the rear O2 wiring harness on the 2000 to see if the wires are burned or nicked. Maybe that is causing the code and not the actual SIMMS.

Good luck <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Did you have to splice in your simms?

For the year 00 trucks, GM has 2 different makes of O2 sensors, and they arent compatible between the two types.

 

NO did not splice anything
BUT tell me more about the two differant kind of
simms gm used so that I may inquire as to the 02 simms my supplier shipped
thanks Johnny

maybe because they aren't made for 02? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
