A fault code was detected during self-diagnosis «00519 Intake manifold pressure sensor».
1. Disconnect wiring connector 1 from intake manifold pressure sensor with intake air temperature sensor 2 (pic. 3.33).
2. Connect the tester V AG 1598/18 to the wiring harness of the engine control unit (pic. 3.34).
3. Check the wires between the tester and the connector for open circuit according to the wiring diagram: pin 3 + socket 37, pin 4 + socket 18. Wire resistance: max. 1.5 ohm.
4. Additionally, check the wires for shorting one to the other. on «mass» vehicle and to the positive pole of the battery.
Specification resistance: ∞ Ohm.
5. If no fault is found in the wiring, replace the intake manifold pressure sensor with the intake air temperature sensor.
