If your mechanic has the correct diagnostic equipment he should be able to locate the exact problem but the information below should help with the throttle motor,TPS and pedal sensor. The code suggests a conflict of information between the 3 components, I would start with the Pedal sensor as they have been known to fail on other vehicles. Sorry about the layout below it was the way it pasted. 3. INSPECT THROTTLE CONTROL MOTOR w/ CLUTCH (a) Disconnect the throttle control motor w/ clutch connector. ( B) Using an ohmmeter, measure the motor resistance be- tween terminal 1 (M+) and 2 (M–). Motor resistance: 0.3 – 100 Ω at 20°C (68°F) If the resistance is not as specified, replace the throttle control motor w/ clutch. (See page SF–43) © Using an ohmmeter, measure the clutch resistance be- tween terminal 3 (CL–) and 4 (CL+). Clutch resistance: 4.2 – 5.2 Ω at 20°C (68°F) If the resistance is not as specified, replace the throttle control motor w/ clutch. (See page SF–43) (d) Reconnect the throttle control motor connector. 4. INSPECT THROTTLE POSITION SENSOR (a) Disconnect the throttle position sensor connector. ( B) Using an ohmmeter, measure the resistance between ter- minals VC and E2. Resistance: 1.25 – 2.35 kΩ at 20°C (68°F) If the resistance is not as specified, replace the throttle position sensor. (See page SF–43) © Reconnect the throttle position sensor connector. 1 3 4 Ohmmeter VC E2 Ohmmeter B01727 2000 LEXUS LS400 (RM717U) Author��: Date��: 1353SF–38 SFI – THROTTLE BODY Ohmmeter VC E2 B01728 5. INSPECT ACCELERATOR PEDAL POSITION SEN- SOR (a) Disconnect the accelerator position sensor connector. ( B) Using an ohmmeter, measure the resistance between ter- minals VC and E2. Resistance: 1.64 – 3.28 kΩ at 20°C (68°F) If the resistance is not as specified, replace the accelerator ped- al position sensor. (See page SF–43) © Reconnect the accelerator pedal position sensor connec- tor. 6. REINSTALL V–BANK COVER
