po138 to po141 problem
on my 03 ram with the hemi i had had the code read out po138 only so i ordered up a new o2 sensor and put it in. the truck drove fine but after about 50miles the check engine light came on so i hooked up my reader to it and now it only says po141. i thought a new sensor would fix the problem but now with the new sensor im reading a different code with the same sensor. any ideas?

thx the sensor is only 2days old so it shold still be under waranty. well the sensor was a little diferent compared to the factory sensor in that the cable was shorter and the sensor reader that actauly stuck into the the exhaust was a little different, dont no if that was because it was a different brand or the wrong sensor but it plugged in all the same and i noticed a fuel economy boost until the new code showed
