Throttle Position Sensor (THROTTLE SENSOR) is installed on the throttle body and is rigidly connected to the throttle axis.
Checking the throttle body
1. Remove the intake air duct and throttle body.
2. Check that there is no gap between the stop and the throttle lever (the damper is closed).
3. Make sure that the additional air supply damper (1) is fully open.
Checking the throttle position sensor
1. Measure the resistance between the sensor terminals.
2. Insert the feeler gauge between the throttle stop and the lever.
3. Measure the resistance between the sensor terminals.
4. Open the throttle valve fully.
5. Measure the resistance between the sensor terminals.
Connector color - Black
Terminals
Gap - Resistance
VC and E2 - 2500-5900 Ohm
VTA and E2 - 0 mm.200 - 5800 Ohm
IDL and E2 - 0 mm to 2300 Ohm
1.6 mm - infinity
VTA and E2 throttle valve open - 1400 - 9500 Ohm

Checking the voltage at the terminals of the throttle position sensor
Terminal - Voltage
1. VC 5 - V (power supply)
2. VTA
Idle speed - 0.45 V
Acceleration - voltage increases with increasing rotation speed
3. IDL
Idle speed - 0 V
Acceleration - changes in a jump to 13 V when you press the accelerator pedal.
4. E2 - "ground"
