Just to clarify things.....
When I get the wrench light, the Zex system isn't even on! I haven't even filled the bottle yet! It is a very intermitent problem... I can see it on the datalogger. I've been on the phone most of the day with Zex... Something is causing the computer to see a unexpected drop in the TPS voltage.... Like I said this is with the Zex unit OFF! It's almost like the unit has some kind of occasional short in it...
Waiting for Zex to call me back again...
