Also, check that there is no friction sound. If operation is not as specified, check the throttle control motor (see step 3 ), wiring and ECM. Inspect the accelerator pedal position sensor. Connect a hand-held tester to the Controller Area Network Vehicle Interface Module (CAN VIM). Then connect the CAN VIM to the Date Link Connector 3 (DLC3). 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 P2120, P2122, P2123, P2125, P2127, P2128,P2138 THROTTLE/PEDAL POSITION SENSOR/SWITCH "D&E" CIRCUIT LOW/HIGH & INPUT THROTTLE/PEDAL POSITION SENSOR/SWITCH "D&E" VOLTAGE CORRELATION»(ref-227566-S09773972092006040600000) ), wiring and ECM. If not using a hand-held tester, measure the voltage between terminals (VTA1-E2, VTA2-E2) of the ECM connector (See «DTC P0120, P0122, P0123, P0220, P0222, P0223, P2135: THROTTLE/PEDAL POSITION SENSOR SWITCH "A&B" CIRCUIT LOW/HIGH INPUT & THROTTLE PEDAL POSITION SWITCH "A&B" VOLTAGE CORRECTION»(ref-227566-S18183041242006040600000) ). 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 compressor ON to OFF, and check the idle speed. Idle speed (Transmission in neutral): 700 +/- 50 RPM NOTE: Perform inspection without an electrical load. After checking the above (a) to (c), perform the driving test and check that there is no sense of incongruity.
3. INSPECT THROTTLE CONTROL MOTOR Disconnect the throttle control motor connector. Using an ohmmeter, measure the motor resistance between terminals M+ and M-. Motor resistance: 0.3 to 100 ohm at 20° C (68° F) If the resistance is not as specified, replace the throttle body assembly (see «REMOVAL»(ref-227590-S27034458912006040600000) ). Reconnect the throttle control motor connector.
4. INSPECT THROTTLE POSITION SENSOR (See «DTC P0120, P0122, P0123, P0220, P0222, P0223, P2135: THROTTLE/PEDAL POSITION SENSOR SWITCH "A&B" CIRCUIT LOW/HIGH INPUT & THROTTLE PEDAL POSITION SWITCH "A&B" VOLTAGE CORRECTION»(ref-227566-S18183041242006040600000) ) If necessary, replace the throttle body assembly (see «REMOVAL»(ref-227590-S27034458912006040600000) ).
