.
CIRCUIT OPERATION
Refer to DTC P2101 - Throttle Actuator Control Motor Magneto Malfunction
.
TECHNICAL DESCRIPTION
ECM checks the electronic controlled throttle system for abnormal conditions.
DESCRIPTIONS OF MONITOR METHODS
- Difference between throttle position sensor (main) output and target opening is greater than the specified value.
MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)
Other Monitor (There is no temporary DTC set in memory for the item monitored below)
Sensor (The sensor below is determined to be normal)
DTC SET CONDITIONS
Check Conditions
- Battery positive voltage is higher than 8.3 volts.
- Throttle position sensor (main) output voltage is between 0.2 and 4.8 volts.
- Drop of throttle position sensor (main) output voltage per 100 milliseconds is more than -0.04 volt.
Judgment Criterion
- The target throttle position sensor (main) voltage subtracted from the throttle position sensor (main) output voltage is more than 0.5 volt for 0.4 second.
Check Conditions
- Battery positive voltage is higher than 8.3 volts.
- Throttle position sensor (main) output voltage is between 0.2 and 4.8 volts.
- Target throttle position sensor (main) output voltage is less than 1.5 volts.
Judgment Criterion
- Difference between throttle position sensor (main) output voltage and target throttle position sensor (main) voltage is 0.6 volt or higher for 0.4 second.
Check Conditions
- Battery positive voltage is higher than 8.3 volts.
- Throttle position sensor (main) output voltage is between 0.2 and 4.8 volts.
Judgment Criterion
- Difference between throttle position sensor (main) output voltage and target throttle position sensor (main) voltage is 1.5 volt or higher for 0.4 second.
Check Condition
- Battery positive voltage is higher than 8.3 volts.
Judgment Criterion
- Throttle position sensor (main) default opening learnt value is 4 volts or higher.
FAIL-SAFE AND BACKUP FUNCTION
- Throttle opening degree position is in default position.
