DTC 612 - FPP LOW VOLTAGE
Circuit Description
The foot pedal position (FPP) sensor uses a variable
resistor to determine signal voltage based on pedal
position. Less depression of pedal results in lower
voltage, and greater depression results in higher
voltage.
This fault will set if voltage is less than 0.2 volts for
greater than 0.30 seconds with engine cranking or
running. Forced idle and low rev limit will be enforced
during this fault. When these are enforced,
maximum engine speed is 1500 rpm. The low rev
limit is enforced for the remainder of the key ON
cylce.
Conditions for Setting the DTC
Foot pedal position.
Check condition - engine cranking or cranking.
Fault condition - FPP sensor voltage less than 0.2.
MIL - on during active fault.
Adaptive - enabled.
Forced idle enforced.
Low rev limit enforced.
