I checked for codes tonight while I was pulling some other data down, and I have this code every day I've been driving for quite some time. The car is running fine, and the SES light is not on. It was just by chance that I pulled the codes down.

Does anyone know if this is from the MTH?

Thanks, I know what the description is, I just don't know if it's MTH related. If no one knows, I'll flash back to stock over the weekend to test. I'm also emailing Franz to see if he's heard of anyone else with it. Unfortunately I had cleared my datalogger's memory several times, and can't pinpoint beyond a week when it first started, so I don't know if it was right after a mod or not.

 

OK I just reflashed to stock and back, code remains even stock, so that rules out MTH.


The only thing unusal that has happened lately is I went through a large puddle of lfooded roadway about 2 wweeks ago, and when the belts got wet the car went nutz. I had to pull over and shut down, then restart for it to go back to normal.

Oh well, it's going in for service soon anyway - one of my horns stopped working last weekend too.
