1. INSPECT SYSTEM OPERATION Inspect the throttle control motor for operating sound. Turn the ignition switch to ON. When turning the accelerator pedal, check the running sound of the motor. If operation is not as specified, check the throttle control motor (See step 3), wiring and ECM. Inspect the accelerator pedal position sensor. Connect the TOYOTA hand-held tester to the DLC3. Turn the ignition switch to ON. Check that the MIL does not light up. When turning the accelerator pedal position sensor lever to the full-open position, check that the throttle valve opening percentage (THROTTLE POS) of the CURRENT DATA shown the standard value. Standard throttle valve opening percentage: 60% or more If operation is not as specified, check that the accelerator pedal position sensor (See «DTC P0120: THROTTLE PEDAL POSITION SENSOR/SWITCH "A" CIRCUIT»(ref-206112-S34883280952005112400000) ), wiring and ECM. If you have no TOYOTA hand-held tester, measure voltage between terminals VPA and E2 of the ECM connector (See «TERMINALS OF ECM»(ref-206112-S40952162522005112400000) ). Inspect the idle speed. Start the engine and check that the MIL does not light up. Allow the engine to warm up to normal operating temperature. Turn the A/C conditioning ON to OFF, and check the idle speed. Idle speed (Transmission in neutral): AT: 750 +/- 50 RPM MT: 800 +/- 50 RPM NOTE: Perform inspection under condition without electrical load. After checking the above (b) to (d), perform the driving test and check that there is no sense of incongruity.
2. INSPECT THROTTLE CONTROL MOTOR Disconnect the throttle control motor connector. Using an ohmmeter, measure the motor resistance between terminal 1 (M-) and 2 (M+). Motor resistance: 0.3 - 100 ohm at 20°C (68°F) If the resistance is not as specified, replace the throttle body (See «REMOVAL»(ref-206126-S15436777132006062000000) ). Reconnect the throttle control motor connector.
3. INSPECT THROTTLE POSITION SENSOR (See «DTC P2120: THROTTLE/PEDAL POSITION SENSOR/SWITCH "D" CIRCUIT»(ref-206112-S08871642662005112400000) ) If necessary, replace the throttle position sensor (See «ACCELERATOR PEDAL POSITION SENSOR»(ref-206126-S33027981912006062000000) ).
