DTC P060E INTERNAL CONTROL MODULE THROTTLE POSITION PERFORMANCE

DESCRIPTION

The ECM monitors the input signals of the Throttle Position (TP) sensor No. 1 and stop light switch. As the
ECM monitors the input signals of the TP sensor No. 1 and the STP signals of the stop light switch, if the input
signals and control signals are deviated, a DTC is output.
