Throttle body
Withdrawal
1. Remove the throttle body air tube.
2. Disconnect the fuel hoses and wires from the throttle body.
3. Disconnect the accelerator cable.
4. Loosen the fixing bolts of the intermediate flange (arrows) and remove the case. Remove the intermediate flange if necessary.
Installation

Installation is carried out in the reverse order of removal.
Throttle Positioning Module
Withdrawal
1. Remove the throttle body air tube.
2. Disconnect the accelerator cable.
3. Disconnect the module connector.
4. Loosen the fixing screws and remove the module.
Installation
Installation is carried out in the reverse order of removal.
Throttle Potentiometer
The potentiometer is located in the lower section of the throttle body and cannot be replaced.
Examination
Check that the resistance between terminals 1 and 5 (models with manual transmission, fig. left) or 1 and 7 (models with automatic transmission, fig. on right) was between 520 and 1300 ohms. When the throttle is opened one quarter, the resistance between terminals 1 and 2 should increase from 600 to 3500 ohms, between terminals 1 and 4 (models with manual transmission) or 1 and 6 (models with automatic transmission) from 600 to 6600 ohms.
Idle system switch
The switch is part of the module and cannot be replaced. Remove the throttle position module.
Throttle damper
Withdrawal
1. Depress the accelerator pedal.
2. Mark the installation position of the damper, unscrew the lock nut and unscrew the damper.
Installation and adjustment
Installation is carried out in the reverse order of removal.
Check that the throttle lever lowers the damper plunger (1) 4-8 mm when closing the throttle. If necessary, adjust the position of the damper so that at fully closed throttle there is a gap A of 0.05 mm between the throttle stop screw and the stop. 2 - locknut.
Oxygen sensor
Withdrawal
The sensor is installed on the exhaust manifold. Disconnect the sensor connector and unscrew the sensor.
Installation
Screw the sensor to the required tightening torque. Plug in the connector.
Coolant temperature sensors
Withdrawal
1. Drain about a quarter of the coolant from the engine.
2. Unscrew the corresponding sensor and disconnect the connector.
Installation and adjustment
Installation is carried out in the reverse order of removal.
