Default 2005 GT Oxygen Sensor help

Is there a difference between the upstream and down stream oxygen sensors (besides length of wire)? I replaced the downstream o2 first and replaced it with a short wire o2 sensor. I figured the upstream would be long but after taking it out I found it to be short too. I do have a long wire o2 sensor but am wondering if I should take it back for a short wire one or just use the long wire. Both were purchased form the dealer. Thanks in advance.

I had the same problem, too. When I had purchased the MOPAR sensors through RockAuto, their website said that both sensors were the same. But when it came time to have them installed, one is supposed to be short wire and one long. I had to send back theirs and get a correct one at my local dealership.

I would say that what your dealership gave you is correct as they would have used your vehicle VIN to look up the parts.

For my PT:

MOPAR 56029050AA upstream
MOPAR 56029049AA downstream

The operation of the H02 sensors are the same. The long wire will work in both locations.

I am still running "Chinese" manufactured no name plain box H02s that came with long wires in both locations now for a few months with NO PROBLEMS!

Just went to replace the upstream and the two connectors are different. I guess our car uses two short wire 02 sensors. Now I get to wait till tomorrow to finish.

What were the 2 part numbers of the sensors that you got from the dealer?

Using a couple of different dealership websites, they show that your PT uses the same senor in both locations:

That's what I'm finding.

That's unusual that the dealership apparently messed up as they should have used the VIN to get the correct parts. I guess you'll find out tomorrow when you go back.

The connectors are different:



MOPAR 56029049AA Upstream is on the left (notches are at 9 - 12 - 3)
MOPAR 56029050AA Downstream is on the right (notches are at 9 - 12 - 2:30)

1 swipe of the xacto knife would fix that.
