Step
1 Was "Engine and Emission Control System Check"
performed?
2 TP sensor and its circuit check
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ON ignition switch, check "TP Sensor 2 Volt"
displayed on scan tool when accelerator pedal is idle
position and fully depressed.
Is displayed TP sensor value as described voltage in "Scan
Tool Data"?
