P0152 Dodge -

Question

I had a Code PO155 - Bank 2, Senor 1 on my Dodge Durango 2001 4,7L.

Used Liquid Wrench to free up the plug.
Replaced the Sensor with a Bosch Premium Oxygen Sensor model # 13937.

Started engine and a lot of smoke came off the areas that Liquid Wrench was residing.

Now I am getting PO152 code.

Any suggestions?

Thank you,
Gregg

Hi there

I would look at the wiring harness for the sensor. It's possible there is a short to power causing the issue. Since it changed after you changed the sensor it's possible you disturbed the wiring and caused the issue.
