[. . . ] Disconnect the accelerator pedal position sensor (2nd channel) connector. Measure resistance between terminal Nos. 1 and 4 of the connector. Measure resistance between terminal Nos. 4 and 3 of the connector. Normal condition: Depress the accelerator pedal slowly. Resistance value changes in accordance with the accelerator pedal depression smoothly. Accelerator pedal position sensor (2nd channel) 4. If not within the standard value, or resistance value does not change smoothly, replace the accelerator pedal position sensor assembly. NOTE After replacement, adjust the accelerator pedal position sensor (2nd channel). (Refer to P. 13A-98. ) GDI <4G6> - On-vehicle Service Equipment side connector 13A-109 ACCELERATOR PEDAL POSITION SWITCH CHECK 1. Disconnect the accelerator pedal position sensor (1st channel) connector. 3 (accelerator pedal position switch) and 4 (sensor earth) of the connector. Normal condition Accelerator pedal Depressed Released Continuity No continuity Continuity (0 W) Accelerator pedal position sensor 3. If defective, replace the accelerator pedal position sensor assembly. NOTE After replacement, adjust the accelerator pedal position sensor and switch. (Refer to P. 13A-98. ) Equipment side connector OXYGEN SENSOR CHECK <Oxygen sensor (front)> 1. Disconnect the oxygen sensor connector and connect the special tool (test harness) to the connector on the oxygen sensor side. Make sure that there is continuity (11 - 18 W at 20_C) between terminal 2 (red clip of special tool) and terminal 4 (blue clip of special tool) on the oxygen sensor connector. Oxygen sensor 3. If there is no continuity, replace the oxygen sensor. Warm up the engine until engine coolant is 80_C or higher. Red Blue Oxygen sensor equipment side connector MD998464 Jumper wire White Red Black Blue 5. Use a jumper wire to connect terminal 2 (red clip) of the oxygen sensor connector to the battery (+) terminal and terminal 4 (blue clip) to the battery ( - ) terminal. Caution Be very careful when connecting the jumper wire; incorrect connection can damage the oxygen sensor. Connect a digital voltage meter between terminal 1 (black clip) and terminal 3 (white clip). MD998464 13A-110 GDI <4G6> - On-vehicle Service 7. While repeatedly racing the engine, measure the oxygen sensor output voltage. [. . . ] The speed adjusting screw is correctly adjusted at the factory and should not be removed. If the speed adjusting screw has been removed, carry out fixed SAS adjustment. If the speed adjusting screw should happen to have been removed, carry out speed adjusting screw adjustment. GDI <4G9> - Throttle Body/Injector Driver CLEANING THROTTLE BODY PARTS 13B-111 1. Do not use solvent to clean the following parts: D Throttle position sensor D Accelerator pedal position sensor D Idle speed control body assembly If these parts are immersed in solvent, their insulation will deteriorate.
