Default Are The Oxygen Sensors The Same?

Looking to change both oxygen sensors and was wondering if they are the same sensor or if they are different? thanks

On my PT, they are different, the length of the lead is different, as well as the connector.

Call any dealership, and using the VIN to your PT, they can tell you what yours has.

If you are buying aftermarket sensors, depending on the brand, most of them use the same sensor for both locations. They simply used longer wire on both and put a plug that will fit in both locations.

If you are buying dealer parts, then they probably will be two different part numbers, with plugs that will fit only their designated positions.

We have speculated that they are actually the same sensor, but with different lengths of wires, similar to what the aftermarket does, since Chrysler also used the PT downstream sensor as an upstream sensor when used in a non-pt car. Probably as a cost cutting measure since wire equals lots of money when you consider the numbers of vehicles being produced. For the aftermarket, the cost of the wire and plug is already built into the cost of the sensor so it is different.

Anyway, why are you looking to swap the sensors? As a maintenance procedure or better fuel economy?

MycKee: I am changing them because an engine code po137 keeps coming on after the car sits for a couple of days.
