Probably posted this in the wrong section the first time. I'll give it a shot here.
Ok guys I'm new here but I have an interesting issue on a Kia Sedona. Came in with a p0138 (bank 1 sensor 2 high voltage) and a p0455 (evap large leak.) monitoring the O2 sensors came up with something a bit odd. The specified range shows to be ~ .06-.07 on b1s2 and b2s2.
So keep in mind the code is for high voltage on b1s2. This is engine warm at idle.
I see that b1s2 voltage is indeed slightly high at times but for the most part it looks to be in range. Now look at b2s2.
Am I wrong in thinking the b2s2 is way out of range? At times almost just as high as b1s2 but mostly low? Drivability is fine except for maybe a slight rough idle. 150k on the odometer. I don't feel I have enough of a cause to bolt a b1s2 on it yet. Shot of both banks together.
Bank 1 Sensor 2 looks to have a slower response than bank 2 sensor 2 but why a high voltage code? Any input would be great!
