Yesterday I had the CEL come on (solid) on my 24 hybrid, soon after a several mile downhill. When my son drove it several hours later he noticed a smell which he thought was similar to ozone. Seems to be driving just fine though. I just checked the code and it is P237F.
Has anyone here had that code? What was the solution?
Did a search and the AI result says it is a problem with the heat exchanger exhaust bypass valve, and that the solution is to reprogram the PCM. It also says there's a TSB 24-2173.
