Trying to diagnose our lift truck! GM 3.4 liter When pressing on gas, the pedal moves almost halfway before engine revs. It does not gradually increase engine speed. I tested the voltage of the tps and its reading 1.2 volts at idle and gradually increases while pushing pedal. No spikes or drops in voltage, so I would say the tps is good. Any ideas? Can codes or sensors be monitored with a standard automotive scanner?
