the ”throttle position sensor” 2005 LEXUS RX330 REPAIR MANUAL (RM1136U) 05−109 DIAGNOSTICS − SFI SYSTEM (3MZ−FE) CIRCUIT DESCRIPTION HINT: This electrical throttle system does not use a throttle cable This throttle position sensor is a non−contact type The throttle position sensor is mounted on the throttle body and it detects the opening angle of the throttle valve This sensor is electronically controlled and uses Hall−effect elements, so that accurate control and reliability can be obtained The throttle position sensor has two sensor elements and signal outputs One element is used to detect the throttle−opening angle and the other is used to detect malfunctions of the sensor itself The voltage is applied to the terminals VTA1 and VTA2 of the ECM changes between V and V in proportion to the opening angle of the throttle valve This sensor includes two signals, VTA1 and VTA2 VTA1 is used to detect the throttle opening angle and VTA2 is used to detect malfunctions in VTA1 There are several checks that the ECM performs to confirm proper operation of the throttle position sensor and VTA1 The ECM judges the current opening angle of the throttle valve from these signals input from terminals VTA1 and VTA2, and the ECM controls the throttle motor to make the throttle valve angle properly in response to driver inputs Throttle Position Sensor ECM Magnet IC No.1 VC VTA1 Throttle

opening angle (a) There is a specific voltage difference expected between VTA1 and VTA2 for each throttle opening angle S If the difference between VTA1 and VTA2 is incorrect, the ECM interprets this as a default and will set a DTC (b) VTA1 and VTA2 each have a specific voltage operating range S If VTA1 or VTA2 is out of the normal operating range, the ECM interprets this as a fault and will set a DTC (c) VTA1 and VTA2 should never be close to the same voltage levels S If VTA1 is within 0.02V of VTA2, the ECM interprets this as a short circuit in the throttle position sensor system and will set a DTC FAIL SAFE If the ETCS has a malfunction, the ECM cuts off current to the throttle control motor The throttle control valve returns to a predetermined opening angle (approximately 16_) by the force of the return spring The ECM then adjusts the engine output by controlling the fuel injection (intermittent fuel−cut) and ignition timing in accordance with the accelerator pedal opening angle to enable the vehicle to continue at a minimal speed If the accelerator pedal is depressed firmly and slowly, the vehicle can be driven slowly If a ”pass” condition is detected and then the ignition switch is turned OFF, the fail−safe operation will stop and the system will return to normal condition MONITOR STRATEGY Related DTCs P0120: TP Sensor Range Check (Chattering) P0122: TP Sensor Range
