EC-284 < DTC/CIRCUIT DIAGNOSIS > [VQ35DE] P0222, P0223 TP SENSOR P0222, P0223 TP SENSOR Description INFOID:0000000010094979 Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc. The throttle position sensor responds to the throttle valve movement. The throttle position sensor has two sensors. These sensors are a kind of potentiometer which transform the throttle valve position into output voltage, and emit the voltage signal to the ECM. The ECM judges the current opening angle of the throttle valve from these sig- nals and controls the throttle valve opening angle in response to driving conditions via the throttle control motor. DTC Logic INFOID:0000000010094980 DTC DETECTION LOGIC NOTE: If DTC P0222 or P0223 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643. Refer to . DTC CONFIRMATION PROCEDURE 1. PRECONDITIONING If DTC Confirmation Procedure has been previously conducted, always perform the following before conduct- ing the next test. 1. Turn ignition switch OFF and wait at least 10 seconds. 2. Turn ignition switch ON. 3. Turn ignition switch OFF and wait at least 10 seconds. TESTING CONDITION: Before performing the following procedure, confirm that battery voltage is more than 8 V at idle. >> GO TO 2. 2. PERFORM DTC CONFIRMATION PROCEDURE 1. Start engine and let it idle for 1 second. 2. Check DTC. YES >> Go to NO >> INSPECTION END Diagnosis Procedure INFOID:0000000010094981 Regarding Wiring Diagram information, refer to . 1. CHECK GROUND CONNECTION 1. Turn ignition switch OFF. 2. Check ground connection E9. Refer to Ground Inspection in . Is the inspection result normal? YES >> GO TO 2. PBIB0145E DTC No. Trouble diagnosis name DTC detecting condition Possible cause P0222 Throttle position sensor An excessively low voltage from the TP sensor • Harness or connectors (The sensor circuit is open or shorted.) • Electric throttle control actuator (Throttle position sensor 1) P0223 Throttle position sensor An excessively high voltage from the TP sensor |
