Hi I have a 2000 Transam with QTP long tubes. I have a problem with my 02 sensors and need to start off by making sure they are plugged in right. My rear 02 sensors are deleted, but I have four possible locations in which to plug them in at. I think I screwed up somewhere, so I want to double check the plug in locations of the FRONT 02 sensors. Can someone please tell me specificly where the passenger and driver front 02 harness is located at? If this is not my problem I think the Bosche 13111's I bought are fautly. Please help, thank you.

 

My QTP's leaked bad like which screwed up the O2's. Here is a link to a thread with some pics. Sell them and buy some Kooks. QTP ignored every email I sent them too.

I'm not quite sure thats the problem, they don't seem to leak. Right now I am more interested in figuring out if i have them hooked up right. For now I pulled the MAF/02 fuse, and it is actually running pretty good right now. I need to get this fixed though asap, any wiring diagrams or something would be great.

 

The two front O2 connectors are mounted close to the Kmember. The two rear connectors are located around the middle of the transmission on each side. Hope this helps.

I have the Bosch sensors I think I got the Camaro ones (13114 maybe?); not the Vette ones. But they are the same sensor just different length cable as I already had the 24" extensions. Haven't had any problem with them.

What symptoms are you having?

 

Well it honestly ran like **** compared to with the 02's disconnected. I think one of them is ****ed up, It would not hold an idle worth ****, and kept wanting to die after coming down from a rev. So the front 02's are where you would expect them to be right, driver side on driver side, etc? Just trying to make sure I got them hooked up right, I think one of the sensor is fubared. What volts does a properly functioning sensor display?

 

Yep, the passenger side is mounted right on the Kmember on that side. Drivers side iirc is in a similar area I believe. I highly doubt you connected them up wrong as the rears are quite a bit farther back.

Voltage I have no clue; maybe somebody else can chime in. Are you throwing any codes?

 

Have you scanned it? The sensors should be switching if they are working properly with the reading going from high to low every second or two.

Ok the sensors are not switching, either reading high or low and that is all. Any idea? why?
