DTC P1575:00 [MZI-3.7]

DTC P1575:00	Pedal position out of self test range
DETECTION CONDITION	• During KOEO self-test, the PCM monitors the APP sensor inputs to determine if the APP1 and APP2 signals are less than an expected value. If either APP1 or APP2 is greater than the expected value, the DTC is set.
POSSIBLE CAUSE	• Accelerator pedal applied during KOEO self-test
