Diagnostic Code PO154

[Brockmeister]

When my CEL light came on, I hadn't done a THING to the car. In fact, I only had it for a month. I was hoping it was something stupid because if it wasn't, I was seriously screwed because I bought the car "AS IS" from the dealer.
Anyway, when I opened up the hatch, the engine bay was really dusty and dirty (still is). I unclipped the connector and the bent the little metal tangs to see if they would get a better connection. It worked. (knock on wood) and it's been 8 months since. If I were you, I would try it just to see what happens. 13 years of heating and cooling may have a minute effect on the electrics.

Well my ECU says it is Bank 2, sensor 1. That means the problem is coming from the passenger/right side of the car at the O2 sensor before the primary cat.

I guess I will check that connection or move the cable around.

Bank 2 Sensor 1 is actually the Drivers side ahead of the cat conv.....had the P0154 fault code last month and changed that O2 sensor myself ...easy to do ....and cleared all codes.
