Air filter elements
1 - body;
2 - filter element;
3 - air flow sensor;
4 - gasket;
5 - filter;
6 - cover;
7 - resonator (1.8 l engines);
8 - gasket;
9 - air pipe;
10 - air cleaner assembly;
11 - air drip;
12 - resonator.
Disconnect connector (1) air flow sensor (2).
Measure the resistance between pins 5 and 6.
Rated value:
- 2.3-3.0 kΩ (at 20°C);
- 0.30-0.42 kOhm (at 80°C).
Measure the resistance by heating the sensor (1) hair dryer.
As the sensor heats up, the sensor resistance should decrease.
If the resistance does not match the required value or it does not change depending on the temperature, then replace the air flow sensor.
