Checking the technical condition
1. Visually check the mass air flow sensor.
A. Installation position.
B. Dirt, corrosion, or damage to the connector.
C. Clogged or wet air filter.
D. Deformed or blocked by foreign material in the sensor cylinder (MAFS).
2. Check for leaks in the intake system and intercooler system.
Withdrawal
1. Turn the ignition key to position «OFF» and disconnect the negative (-) battery wire.
2. Disconnect the connector (A) mass air flow sensor and remove the clamp (IN).
3. Turn away fixing bolts and remove the gauge of the mass expense of air.
Installation
Attention.
- Tighten the component mounting bolts to the correct torque.
- Be careful not to drop the component. In the event of a fall, the component must be carefully checked before installation:
- Be careful not to damage the sensing element and honeycomb.
Installation is carried out in the reverse order of removal.
Note: Tightening torque:
- Bolt for mounting the mass air flow sensor: 3.9-5.9 Nm.
- Clamp screw for mass air flow sensor: 2.9 - 4.9 Nm.
Replacement
Attention. After replacing the mass air flow sensor (MAFS) you need to follow the procedure «Component Change Routine» (Component replacement program). Otherwise, a malfunction related to engine performance or exhaust control may occur and remain until the data on the new component is registered in the engine control unit.
1. Turn off the ignition.
2. Connect the diagnostic system scanner (GDS) to the diagnostic socket (DLC).
3. Turn on the ignition.
4. Select «Vehicle, Model year, Engine, System» (car, model year, engine, system).
5. Select «Vehicle S/W Management» (Vehicle software control).
6. Select «Component Change Routine» (Component replacement program).
7. Select "AIR FLOW SENSOR CHANGE" (Air flow sensor replacement).
8. Follow the procedure as instructed on the screen.
