1995 Dodge Dakota Q&A

1995 Dodge Dakota Question: Bad connection at pcm

I as well have replaced every sensor under the hood and checked the wiring in the harness only to track it down to a loose plug at the PCM after it warms up a bit and i start going down some rough road. Really stinks spent about 300 on just little stuff but fingers crossed this was the real reason. -
Answer 1
Good luck, may have to secure the plug if it's not locking. -

The light is on all the time. The manuel for this vehicle says the code is po155.If I change the upstream, right bank 02 sensor, will that fix the problem, and make the light go off and stay off?
