Range Rover (LM) V8-4.2L SC (2006)
APP Sensor Output Graph
The APP sensor has two potentiometer tracks which each receive a 5 V input voltage from the ECM (engine control module). Track 1 provides an output
of 0.5 V with the pedal at rest and 2.0 V at 100% full throttle. Track 2 provides an output of 0.5 V with the pedal at rest and 4.5 V at 100% full throttle.
The signals from the two tracks are used by the ECM (engine control module) to determine fuelling for engine operation and also by the ECM (engine
control module) and the TCM (transmission control module) to initiate a kickdown request for the automatic transmission.
