EC-398 < DTC/CIRCUIT DIAGNOSIS > [VQ35DE] P2101 ELECTRIC THROTTLE CONTROL FUNCTION 3. Disconnect IPDM E/R harness connector. 4. Check the continuity between IPDM E/R harness connector and ECM harness connector. 5. Also check harness for short to ground and short to power. Is the inspection result normal? YES >> GO TO 3. NO >> Repair open circuit, short to ground or short to power in harness or connectors. 3. CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL CIRCUIT 1. Check the continuity between IPDM E/R harness connector and ECM harness connector. 2. Also check harness for short to ground and short to power. Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit. NO >> Repair open circuit, short to ground or short to power in harness or connectors. 4. CHECK THROTTLE CONTROL MOTOR OUTPUT SIGNAL CIRCUIT FOR OPEN OR SHORT 1. Turn ignition switch OFF. 2. Disconnect electric throttle control actuator harness connector. 3. Disconnect ECM harness connector. 4. Check the continuity between electric throttle control actuator harness connector and ECM harness con- 5. Also check harness for short to ground and short to power. Is the inspection result normal? YES >> GO TO 5. NO >> Repair or replace malfunctioning part. 5. CHECK ELECTRIC THROTTLE CONTROL ACTUATOR VISUALLY 1. Remove the intake air duct. Refer to . 2. Check if foreign matter is caught between the throttle valve (1) - Electric throttle control actuator (2) - : Vehicle front Is the inspection result normal? YES >> GO TO 6. NO >> Remove the foreign matter and clean the electric throttle control actuator inside, refer to , and then perform throttle valve closed position learning. .
