Dtc P0154

[icecoldtexan]

I scanned my dtc's a couple weeks ago and noticed the code P0154, indicating the bank2 sensor1 no activity detected. I thought this to be the passenger side front sensor.. I swapped both front o2s sensors to see if it would throw the opposite code to verify it is the o2s sensor before I bought a new one. I just scanned my codes again and got the same P0154 code, so it must not be the o2s sensor ? What else can cause this dtc to show up ? My instrument panel never indicated a problem, I just happened to find the code when I scanned for dtc's.

I just had the same problem, but I would get the code when it would get wet. So i bought a new o2 senser and when i took the old one off i noticed one of the wires were worn down and a bare part so I think it was shorting out. so check out the cable.
