Try the EVAP service bay test on the 2011 Silverado please. I have a 2013

@737mechanic waiting for them to add Battery voltage in top right corner Reference values (minimum / maximum) Update GMV 13.19 Fixed EVAP service bay test

[@twisted-lj2xk]

Im getting TPS circuit low. Where would that reference voltage issue come from? Actual % outputs look good.

[@secretchipmunk7]

My sensors read .92 and .88 and says disgree. Is it the pedal? Or can it be wiring? 2005 grand Prix. I'm just worried that I'm being told to replace a new pedal for no reason

[@737mechanic]

It could be wiring and it would be a good idea to ring the wiring out with a multimeter and make sure it is good before replacing anything.

In some other cars, the signals might agree but not in all cases.

[@ernestdamo677]

Good explanation but please what is the voltage of sensor 1 and sensor 2 at idle

[@737mechanic]

About 1.34v for sensor 1 and .67 for sensor 2.
