Engine Code

[JHarris1385]

I have this on show up everyday. The problem is I do not know what to do to correct it. I also do notice any negative effects from it.


P1153
H02S Insufficient Switching Bank 2 Sensor 1


Any insight?


Thanks!

Initial guess:

The readings from a heated oxygen sensor are not bouncing up and down like they should. Your engine is probably running just fine, but the computer is paranoid about air quality regulations.

First, check the wiring harnesses connecting to the oxygen sensors, then check the plugs going into the computer (behind the panel under the CD player).

I don't know where the O2 sensors are, though. Look for things bolted into your exhaust system pipes with wires coming off of them.
