ON-VEHICLE INSPECTION
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:
600 to 700 rpm
NOTICE:
(2) Perform a road test and confirm that there are no abnormalities.
(b) Inspect the throttle position sensor.
(1) Connect the Techstream to the DLC3.
(2) Start the engine.
(3) Turn the Techstream on.
(4) Enter the following menus: Powertrain / Engine / Data List / Throttle Position Sensor No.1 Voltage %.
Powertrain > Engine > Data List
