1
Was “Engine and Emission Control System Check”
performed?
Go to Step 2.
Go to “Engine and
Emission Control
System Check: ”.
2
Throttle position sensor and its circuit 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
Inspection: in Section
00”.
Go to Step 3.

ECM voltage check
1) Disconnect connector from electric throttle body
assembly with ignition switch turned OFF.
2) Check for proper connection to electric throttle body
assembly at “RED”, “GRN”, “WHT” and “BLK” wire
terminals.
For J20 engine
For M16 engine
3) If OK, measure voltage between “WHT” wire terminal of
electric throttle body assembly connector and engine
ground with ignition switch turned ON.
Is voltage 4 – 6 V?
Go to Step 6.
Go to Step 4.
4
Wire harness check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Measure resistance between “C37-53” terminal of ECM
connector and engine ground.
Is resistance infinity?
Go to Step 5.
“WHT” wire is shorted to
other circuit.
