DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC by using scan tool.
3) Keep the accelerator pedal at idle position for 2 sec.
4) Keep the accelerator pedal at fully depressed position for 2 sec.
5) Repeat Step 3) and 4) for 3 times.
6) Check DTC.
DTC Troubleshooting
5 APP sensor power supply voltage check
1) Connect connectors to ECM.
2) Turn ignition switch ON position.
3) Check that circuit voltage is 5 V between APP sensor
(sub) power supply terminal and vehicle body ground.
Is it in good condition?
Go to Step 6. Substitute a known-
good ECM and recheck.
6 APP sensor check
1) Check APP sensor for performance referring to
“Accelerator Pedal Position (APP) Sensor Assembly On-
Vehicle Inspection in Section 1C”.
Is it in good condition?
Substitute a known-
good ECM and recheck. Replace APP sensor
assembly.
Step Action Yes No
DTC detecting condition Trouble area
Difference between the opening angle based on TP sensor
(main) and the opening angle based on TP sensor (sub) is more
than specification for 0.2 sec.
(1 driving cycle detection logic) • TP sensor and/or its circuit
• Electric throttle body assembly
• ECM
Step Action Yes No
1 Was “Engine and Emission Control System Check”
performed? Go to Step 2. Go to “Engine and
Emission Control
System Check”.
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 1 Volt” and
“TP Sensor 2 Volt” displayed on scan tool when
accelerator pedal is released and fully depressed.
Is displayed 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.
3 TP sensor check
1) Check TP sensor for performance referring to “Electric
Throttle Body Assembly On-Vehicle Inspection in
Section 1C”.
Is it in good condition?
Go to Step 4. Replace electric throttle
body assembly.
