This is strange. About 5 months ago my check engine light came on and the code was 21, oxygen sensor or sensor heater. Didn't come back on for awhile, maybe 3 weeks later. Then about a month ago it came on again, same code. then nothing for a couple days. Then it started coming on every other day or so and I realized it was showing up on the same road at the same spot. Almost every time I drove by (only heading home never away from home). So anyway I bought two new sensors since the old ones are the originals with 250K on them. Never got around to installing the sensors and never saw the light again and it has been over a month. Strange!
I guess I will put the new sensors on anyway.
