Circuit Description

Powertrain Control Module (PCM) supplies a 5-volt reference signal and a ground circuit to Throttle Position (TP) sensor. TP sensor signal voltage should be about .5 volt at idle and 4.5 volts or more at wide open throttle.

Conditions required to set DTC:

• MAP voltage is less than 37 kPa.
• TP sensor dose not change more than 2 percent
• DTC P0107, P0108 and/or P0122 are not set.
• TP sensor angle is more than 60 percent at 1600 RPM.
• TP sensor angle is more than 77 percent at 2400 RPM.
• TP sensor angle is more than 89 percent at 3200 RPM.
• TP sensor angle is more than 100 percent at 4000 RPM.
