CEL 0138

[InfinitySRT]

Took the truck out for a little spin tonight and the CEL light popped on, I thought it was the usual error code from the Cat delet but it pulled up a code I've never seen, 0138? Can anyone tell me what that is?

P0138-O2 SENSOR 1/2 CIRCUIT VOLTAGE TOO HIGH - SRT10

EDIT: what did you do with your rear O2s when you deleted your cats? sims? hung them from the frame?

P0138 02 Sensor circuit high volts (bank 1 Sensor 2) Means the O2 1/2 signal circuit shorted to battery voltage. If this proves true from a voltage test per maintenance manual you will need to replace the O2 sensor.

Thanks everyone, so its just another O2 sensor fault, no worries then. I haven't driven her in some time and the battery was low so maybe its a voltage issue and not real, either way its no biggy. I have the Mopar long tubes with mids that have the taps for the O2 sensors front and rear just catless. I think that I may have to part ways with my SRT soon and if that happens these will be up for sale along with the MBRP exhaust and a few other items but we'll see what happens
