Code....PO138 02 (Circuit High...........

My airbag icon light on all the time.
Took a code reading, it reads exactly as below.

PO138
02 Circuit High
Voltage ( Bank 1,
Sensor 2 )

Someone know what this code is?

Thanks in advance

You don't say what vehicle but Bank 1 is the one where cylinder 1 is.
For an non-transverse engine, it's the bank on the passenger side of
the vehicle. Sensor 2 would be the one downstream in the exhaust
(towards the rear for a non-transverse engine.

It's telling you that that O2 sensor has high voltage - probably bad
sensor, or might be problem in the cable to the sensor.

 

Bill, I realized after posting I did not clarify vehicle,
it is a 2006 Dodge Caravan, 6cyl, 3.3L

What ever happened to Glenn Beasley (Maxpower) ??

I don't think he's posted to usenet since late October / 2008...

 

And last appearance I can find anywhere on the web was June 2009 on
chryslerforum.com.

 

Looks like he's over at:
