System Check”.
2 Electric throttle body assembly system check
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ON ignition switch, check each voltage of “TP
Sensor 1 Volt” and “TP Sensor 2 Volt” displayed on scan
tool when accelerator pedal is idle position and fully
depressed.
Is displayed each TP sensor value as described voltage in
“Scan Tool Data”?
Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
