Hi,
Not sure if this is where I post this, hopefully someone can help me. I have an 06 Hyundai Tucson. It is throwing many codes. The codes are for 3 o2 and mass air flow sensors. We have replaced the mass air flow and the o2 sensors all in the past 6 months. All the code came on while i was driving 67 miles an hr on the highway. Any ideas?? Any help would be greatly appreciated, I need to get it to pass inspection.

Vacuum leaks are definitely suspect causes from these codes
Stuck injectors?
Frayed wiring, shorts, opens??

Good luck

The guesses would be more educated if we knew what the actual codes were?
I assume you've replaced all those sensors in an attempt to fix this problem?
So this is something that's been happening over the last 6 months?
Maybe you should tell us the whole story.
