SYMPTOM AND CAUSE OF SYSTEM MALFUNCTION HINT: The following are descriptions of the characteristics of each system malfunction...
MONITOR DESCRIPTION The ECM monitors the signals received from the No. 1 throttle position sensor. As the ECM monitors the VTA1 signal of the No. 1 throttle position sensor, if these signals do not correlate, a DTC will be stored. DTC No. Detection Item DTC Detection Condition Trouble Area MIL Note P060E49 Internal Control Module Throttle Position Performance Internal Electronic Failure Either of the following conditions is met (1 trip detection logic):
ECM main CPU malfunction...
