Vision Function Stage 2 P0172 (Too Rich) - LotusTalk

Westrock · 11-07-2009, 05:29 PM

I cant seem to get this little bugger to go away. I had Charlie reflash the ECU with the most recent revision, but P0172 still comes back as soon as the OBD systems pass readiness. I dont get the stumlbing anymore that I use to right before it would show up, but it still shows up none-the-less.

Everything seems fine, car drives great, no hesitations. P0172 would be looking at short/long term fuel trims, not the exhaust right?

maybe your air filter is dirty or MAF is dirty and not getting correct airflow. Just guessing here...

I replaced the MAF and so far have about 70 miles on the car so far since resetting, no CEL yet. I'll have to check to see if the status of the emissions systems has set yet.

The only thing I can think of is that I used some MAF cleaner on the sensor when I did the supercharger install. I never had CEL issues before the supercharger.
