I hope somebody can help me. Has anybody replaced the sensors on this truck? Please give me any info you have. Thanks!!!!!

 

depending on your emissions package your gonna have either 1 or 2 cats.. either way you should only have 2 02's one before the cat and one after the cat.. its pretty simple.. unbolt the old ones.. unplug them.. plug in the new ones.. and put them back in.. youll noticed that you have to unthread the 02's a few times to get them out.. take this into consideration.. you may want to counter turn the wires so that when the 02 is reinstalled the wires are in a twisted mess, but rather straight and unstrained.

do a PCM reset (disconnect the neg. batt. cable and hold your key to the START position for 30 seconds..)
