Two weeks ago my check engine light lit up. I checked and found the code P0157H "low voltage, oxygen sensor #2". I cleared the code at the time and have driven it several hundred miles since. This morning it happened again. Once more, I got a P0157H.
I have two questions:
1)If the code is freshly generated (as indicated by the check engine light), why the "H" (history)??
2)What could be causing the low voltage condition?
Any help would be appreciated!
Thanks,
Dave
