CAUTION / NOTICE / HINT

Note

Inspect the fuses for circuits related to this system before performing the following procedure.

Tech Tips

Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE

CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P2107)

Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes.

Read the DTCs.

DTC P2107 is output	A
DTC P2107 and other DTCs are output	B

Tech Tips

If any DTCs other than P2107 are output, troubleshoot those DTCs first.

READ FREEZE FRAME DATA

Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.

Using the GTS, confirm the vehicle conditions recorded in the freeze frame data which were present when the DTC was stored.

REMOVE FOREIGN MATTER (CLEAN THROTTLE BODY WITH MOTOR ASSEMBLY)

Clean off any deposits from the inside of the throttle body assembly.

*3	Valve	-	-
*a	Reference	*b	Throttle Body with Motor Assembly Cross-section Diagram
*c	When valve fully opened	*d	Do not directly apply cleaner
*e	Deposits	-	-

Push open the throttle valve and wipe off any carbon from the valve and bore using a piece of cloth soaked in non-residue solvent.

Note

Make sure that the cloth or your fingers do not get caught in the valve.
Make sure that foreign matter does not enter the throttle valve.
Do not directly apply non-residue solvent to the throttle body with motor assembly or wash the throttle body with motor assembly. Cleaning solvent may leak into the motor from the shaft and cause problems such as rust or valve movement problems.
If there is coating material on the edge of the valve, be careful not to remove it.
Push the throttle valve open gently with your finger and check that the throttle valve moves smoothly.

Tech Tips

If the throttle valve does not move smoothly, replace the throttle body with motor assembly.
Perform "Inspection After Repair" after cleaning the throttle body with motor assembly.

CHECK WHETHER DTC OUTPUT RECURS

Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Clear the DTCs.
Turn the engine switch off and wait for at least 30 seconds.
Turn the engine switch on (IG).
Turn the GTS on.
Start the engine.
Warm up the engine.
Drive the vehicle in accordance with the driving pattern described in Confirmation Driving Pattern.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P2107.

Check the DTC judgment result.
