check engine light

[Glenn Lyle]

the ce light was scanned and was told i needed 3 O2 sensors. several of you suggested checking the plastic elbow. where is it located, the pix shown are hard to get my bearings with. I believe i've seen it on the pass. side of motor, towards the front of the motor. ALSO, how hard is it to get to, to remove and replace. What all has to come off or be moved?



Thanks.

Here are the pictures again. You will find the hose just below the intake plenum where the plenum is bolted to the intake on the passengers side. The hose hugs the intake pretty close and bends around the intake for the front cylinder on the passengers side.

That is the vacuum hose. We had ours replaced on our '01 as well. What was the code that was read out by the scanner? If it was P0401, then it is probably your DPFE sensor.
