Adjustment of the sensor of position of a pedal of an accelerator and the switch of idling
Attention: adjusting the accelerator pedal position sensor and idle switch may adversely affect the operation of the engine management system. Adjust these components only when replacing them.
1. Install the accelerator pedal position sensor and idle switch to the pedal. Lightly tighten the pedal position sensor mounting bolts and the idle speed switch locknut.
2. Connect the connectors to the accelerator pedal position sensor and idle switch.
3. Set the ignition switch to the "OM" (engine off).
4. Measure the voltage between the terminals "A" And "D" sensor.
- Voltage - 4.9 - 5.1 V (nominal value 5.0 V)
5. Connect the scanner to the diagnostic socket and, using the scanner, check the readings of sensors No. 1 and No. 2 of the accelerator pedal position (APP and APP2).
6. Adjust the position of the sensor so that when the accelerator pedal is fully released, the readings of both sensors correspond to the nominal ones.
- Voltage - 0.5 - 07 V (nominal value 0.6 V)
7. Tighten bolts of fastening of the gauge of position of a pedal of an accelerator.
8. Depress the accelerator pedal by hand until the accelerator pedal touches the rubber stop as shown in the figure. Adjust the position of the limiter so that when it is touched by the pedal, the voltage of the signals of the pedal position sensors corresponds to the nominal voltage.
- Voltage - 3.4 - 3.8 V (nominal value 3.6 V)
9. Select the idle switch option on the scanner (IVS).
10. Gradually depressing the accelerator pedal, adjust the position of the idle switch so that the IVS reading changes from "ON" on "OFF" at the voltage of the signals of the APP and APP2 sensors, corresponding to the given one.
- Voltage - 1.0 - 1.2 V (nominal value 1.1 V)
11. Tighten the idle switch locknut.
- Tightening torque - 13 - 15 Nm
12. Release the accelerator pedal and check that the IVS reading has changed from "OFF" on "ON" with the pedal fully released.
13. Depress the accelerator pedal again and check that the IVS reading has changed from "ON" on "OFF" at the time specified in paragraph "10" voltage of signals from sensors APP and APP2.
