i have no trouble getting the o2 sensor loose from the pipe just cant get it undone from the wiring harness, any suggestions thanks

 

I'll guess you mean 1-1 sensor by the transmission dipstick tube. It's easiest to me to go in through the right front fenderwell to unplug it.

 

My hands were a little too big to get that clip undone and pull the plug apart, so I ended up using a flatblade screwdriver to hold the pin thing down and then seperated the plug.

 

remove the tire and inner fender well takes about 5 minutes.

you will have excellent access

 

thanks guy ill try taking the wheel and everything off in the morning, also looks like im going to have fun messing with the sensor on the passenger side

 

I just did both of mine today. The passenger side was simple with the removal of the tire and the inner wheel well and the driver's side I did from underneath. The sensor connections are secured by the same type of push-in plastic bolts that are used on the body in other places. They hold the socket to the block. So you can pull them loose from the block, disconnect the old sensor, reconnect the new sensor and then reattach it to the block.

Good luck!

 

i finished putting them in, thanks for the advices, hardest thing for me was getting the wiring harnness plugged in on the passenger side, took awhile because i couldnt get my had past the trans check hose.

 

Yeah, I just undertook this last weekend as well. The driver's side was relatively easy, as I could get my hands up in there. The passenger side however I had to get a small screwdriver in there to depress the clip. Definitely don't want to replace those for another 50,000 miles.

 

did you guys notice any difference after you replaced them?

 

yea my truck runs better, and i could tell it had a better response, now i just got to change the spark plugs this weekend
