6. CHECK THE TPS RESISTANCE • Check resistance between TPS terminal 2 and terminal 3. • 2 k⍀ ± 20 % (20°C) should exist. • Also check the resistance between TPS terminal 6 and terminal 2 while turn the throttle. • The resistance should linear change. Is the check result normal? Yes >> Go to the next step. No >> Replace the TPS. 7. CHECK THE TPS SIGNAL • Turn ignition switch off. • Connect ECM connector. • Connect TPS connector. • Turn ignition switch on. • Check voltage between TPS terminal 3 and ground under the following conditions: ECM TERMINAL NO. ITEM CONDITION DATA (DC VOLTAGE) 32 Regulated sensor supply Ignition switch: ON - Approximately 5 V 38 Electronic throttle control actuator (Position sensor) • Engine stopped • Accelerator pedal: 4.24 V • Engine stopped • Accelerator pedal: 0.72 V 54 Electronic throttle control actuator • Engine stopped • Accelerator pedal: 0.74 V • Engine stopped • Accelerator pedal: 4.62 V 78 Sensor (GND) - Approximately 0 V 64 Motor 4 12 V or 0 V 65 Motor 3 66 Motor 2 12 V or 0 V 67 Motor 1 Is the check result normal? Yes >> Go to the next step. No >> Replace the TPS. DIAGNOSIS & TESTING 03
