EC-288 < DTC/CIRCUIT DIAGNOSIS > [QR25DE] P0222, P0223 TP SENSOR 2. CHECK THROTTLE POSITION SENSOR 1 POWER SUPPLY 1. Turn ignition switch OFF. 2. Disconnect electric throttle control actuator harness connector. 3. Turn ignition switch ON. 4. Check the voltage between electric throttle control actuator harness connector and ground. Is the inspection result normal? YES >> GO TO 4. NO >> GO TO 3. 3. CHECK THROTTLE POSITION SENSOR 1 POWER SUPPLY CIRCUIT 1. Turn ignition switch OFF. 2. Disconnect ECM harness connector. 3. Check the continuity between electric throttle control actuator harness connector and ECM harness con- nector. 4. Also check harness for short to ground. YES >> Perform the trouble diagnosis for power supply circuit. NO >> Repair or replace error-detected parts. 4. CHECK THROTTLE POSITION SENSOR 1 GROUND CIRCUIT 1. Turn ignition switch OFF. 2. Disconnect ECM harness connector. 3. Check the continuity between electric throttle control actuator harness connector and ECM harness con- nector. 4. Also check harness for short to power. YES >> GO TO 5. NO >> Repair or replace error-detected parts. 5. CHECK THROTTLE POSITION SENSOR 1 INPUT SIGNAL CIRCUIT 1. Check the continuity between electric throttle control actuator harness connector and ECM harness con- nector. + − Voltage (Approx.)
