DTC Detecting Condition and Trouble Area
Step Action Yes No
1 Was “Engine and Emission Control System Check”
performed?
Go to Step 2. Go to Step “Engine and
Emission Control
System Check”.
2 Throttle valve visual check
1) Check that there isn’t any foreign matter caught between
throttle valve and throttle body housing referring to
“Throttle Valve Visual Check” under “Electric Throttle
Body Assembly On-Vehicle Inspection in Section 1C”.
