PROCEDURE

1. INSPECT THROTTLE BODY WITH MOTOR ASSEMBLY

(a) Check the idle speed.

(1) Start the engine and check that the MIL is not illuminated. After the engine is warmed up, check that the idle speed is within the specified range with the A/C switch off.

Standard Idle Speed:

950 to 1050 rpm

NOTICE:

  • Be sure to perform this step with all accessories off.
  • Make sure that the shift lever is in P or N.

(2) Perform a road test and confirm that there are no abnormalities.

(b) Inspect the throttle position sensor.

(1) Connect the GTS to the DLC3.

(2) Start the engine.

(3) Turn the GTS on.

(4) Enter the following menus: Powertrain / Engine / Data List / Throttle Position Sensor No.1 Voltage %.

Powertrain > Engine > Data List

Tester Display

Throttle Position Sensor No.1 Voltage %

(5) According to the display on the GTS, read the Data List while fully depressing the accelerator pedal and check that the value is 60% or higher.

If the value is less than 60%, check the throttle body with motor assembly, wire harness and ECM.
