2006 Fault Code Question

I went in to get my 06 2500 Sprinter smogged here in the Peoples Republic of Kalifornia, and they said I failed due to fault code PO132 "O2 Sensor High Voltage (Bank 1 Sensor 1)"

The goofy thing is, there was no check engine light on the dash when I went in, but there is now. (I can think of several things not related to any engine problem)

But, can one kind soul enlighten me on this code? Do I have to go to Dodge to get it cleared?

Thanks much

That code implies that the voltage returned by the O2 sensor is too high. Chances are that there is a bad ground connection to the sensor. :2cents:

I can't enlighten you on that particular code (it was probably read by an OBDII generic scan tool, not a Sprinter specific one), but there is some info about O2 sensors and resulting malfunction codes here.

You should be able to clear the code with a generic OBDII scan tool so you shouldn't need a dealer. Be aware that in doing that you will also clear many of the codes which a Sprinter specific scan tool will see which the OBDII generic doesn't. That means you lose some historical data. Have fun. vic

how does a sensor - presumably ok from the factory - develop a bad ground connection; corrosion or vibratory/mechanical/thermal fluxuation stress on the wire over time?

Simply clearing the codes will also set a "Not Ready" code in the OBD-II system.
Emission testers will fail you until that "Not Ready" has been changed to "ready" by numerous start/stop and driving cycles
(about ten, if memory serves).
So drive around for a few days after clearing any codes.

I do not suspect the sensor itself. With the sprinter's history of wiring issues I would check the connections between the sensor and the ECU. It is a simple and inexpensive check that might produce some results.
The P0132 is a generic code so it may not mean anything at all to a sprinter.
