Hello all,
Been awhile but here I come for some guidance once again. I am getting tired of my check engine light going off and on and finally had time to begin looking at it. It goes and comes and lately has just stuck on. My fuel economy is not horrible 19.1 going back and forth to work mix of highway (75mph) and city. I decided to pull my PCM EC1551E connector and start from there. Here is what I found in reference to code P0151. There is no resistance between any combination of pins except E61 and E46 for bank 2 sensor 1. To compare I did the same for bank 1 sensor 1, result to me is about the same. Knowing these are wideband sensors and the lack of having a OBD scanner maybe these values and tests mean nothing. Anyone ever dealt with something like this? My problem it went away for awhile then kept coming back on. Highway driving usually clears it when on city it returns. Any help tips are much appreciated.
