EG–444 ENGINE – 2JZ–GE ENGINE TROUBLESHOOTING 2 Check throttle position sensor Vacuum 1 (E2) 2 (IDL1) 3 (VTA1) Throttle Opener P11462 P (1) Disconnect throttle position sensor connector. (2) Disconnect the vacuum hose from the throttle body, then apply vacuum to the throttle open– er. (See page EG–219) C Measure resistance between terminals 3 (VTA1), 2 (IDL1) and 1 (E2) of throttle position sensor con- nector when the throttle valve is opened gradually from the closed condition. OK Terminal 3 (VTA1) – 1 (E2) 2 (IDL1) – 1 (E2) Throttle Valve Fully Closed 0.3 – 6.3 kΩ Less than 0.5 kΩ Fully Open 2.4 – 11.2 kΩ 1 MΩ or higher Hint Resistance between terminals 3 (VTA1) and 1 (E2) should increase gradually in accordance with the throttle valve opening angle. OK NG Adjust or replace throttle position sensor. (see page EG–223) 3 Check for open and short in harness and connector between engine control module and throttle position sensor (See page IN30).
