Is there continuity?

YES -Substitute a known-good throttle actuator control module (see THROTTLE ACTUATOR
CONTROL MODULE REPLACEMENT ), then go to step 50 and recheck. If DTC U0107 is not
indicated, replace the original throttle actuator control module (see THROTTLE ACTUATOR
CONTROL MODULE REPLACEMENT ), then go to step 50. If DTC U0107 is indicated, go to step
56.

NO -Repair open in the wire between the ECM/PCM (B20) and the throttle actuator control module, then
go to step 50.

46. Turn the ignition switch OFF.

47. Jump the SCS line with the HDS.

48. Disconnect ECM/PCM connector A (31P).

49. Check for continuity between body ground and ECM/PCM connector terminals A8 and A9 individually.

Is there continuity?

YES -Check for poor connections or loose terminals at the throttle body, the throttle actuator control
module relay, the throttle actuator control module, and the ECM/PCM, then go to step 1.

NO -Repair open in the wire between the ECM/PCM (A8, A9) and G101, then go to step 50.

50. Turn the ignition switch OFF.

51. Reconnect all connectors.

52. Turn the ignition switch ON (II).

53. Reset the ECM/PCM with the HDS.

54. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).

55. Check for Temporary DTCs or DTCs with the HDS.

If DTC U0107 indicated?

YES -Check for poor connections or loose terminals at the throttle body, the throttle actuator control
module relay, the throttle actuator control module, and the ECM/PCM, then go to step 1.

NO -Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the
INDICATED DTCS TROUBLESHOOTING.

56. Reconnect all connectors.

57. Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ), or

substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ).

58. Check for Temporary DTCs or DTCs with the HDS.

Is DTC U0107 indicated?

YES -Check for poor connections or loose terminals at the throttle body, the throttle actuator control
module relay, the throttle actuator control module, and the ECM/PCM. If the ECM/PCM was updated,
substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then recheck. If the
ECM/PCM was substituted, go to step 1.

NO -If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see ECM/PCM REPLACEMENT ). If any other Temporary DTCs or
DTCs are indicated, go to the INDICATED DTCS TROUBLESHOOTING.

APP SENSOR REPLACEMENT

1. Remove the throttle cable cover (see THROTTLE CABLE ADJUSTMENT ).

2. Remove the throttle cable (see THROTTLE CABLE REMOVAL/INSTALLATION ).

4. Remove the bolts (B), and the APP sensor (C).

5. Install the parts in the reverse order of removal.

APP SENSOR SIGNAL INSPECTION

1. Connect the HDS to the data link connector (DLC) (A) located behind the driver's side of the dashboard.

NOTE:



This procedure checks the APP sensor in its fully closed position. In any
other position, the APP sensor stores DTCs which are covered in other
troubleshooting procedures.



Check for Temporary DTCs or DTCs with the HDS before doing this
procedure. If any DTCs are indicated, troubleshoot them first, then do this
procedure.



Press the accelerator pedal several times to check its operation. If it does
not operate properly, check the pedal, the throttle cable, and the APP
sensor individually. If you find a problem in one of them, replace the part
(s) that caused the problem.

2. Turn the ignition switch ON (II).

3. Make sure the HDS communicates with the vehicle and the ECM/PCM. If it doesn't, go to the DLC

circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ).

4. Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the

HDS.



If it is below 2 %, the APP sensor is OK.



If it is above 2 %, adjust the throttle cable (see THROTTLE CABLE ADJUSTMENT ), then go
to step 5.

5. Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the

HDS.



If it is below 2 %, the APP sensor is OK.



If it is above 2 %, update the ECM/PCM if it does not have the latest software (see UPDATING
THE ECM/PCM ), or substitute a known-good ECM/PCM (see SUBSTITUTING THE
ECM/PCM ), then go to step 6.

6. Make sure the accelerator pedal is not pressed, then check the APP SENSOR in the DATA LIST with the

HDS.



If it is below 2 %, the APP sensor is OK.



If it is above 2 %, replace the APP sensor (see APP SENSOR REPLACEMENT), then go to step
1.

THROTTLE ACTUATOR CONTROL MODULE REPLACEMENT

1. Push the tab (A), and disconnect the throttle actuator control module 16P connector (B).
