Since the last time I was working with with the MSII, I have lost signal for the coolant temp, air temp, and TPS (Well, the TPS gives a signal, but only from 0 to 11 which only registers a wiggle on the gauge.) All of these were working fine last time I was trying to tune. No changes have been made to the wiring, which is fully secure and sound. I don't get it. Any ideas, anybody??

Thanks

All three are driven from the 5vref pin. Measure the voltage there - anything? Any burned / broken pins, leads, wires?

Well, good news - before taking things apart, I reflashed the code and it started working normally again. Not sure why I decided to do that, but it was a good hunch. Thanks for the tip on the 5V though.
