YES
The actual value is okay.Further possible causes of fault
- Unmetered air
- Signal wire
- B2/5 (Hot film mass air flow sensor)
End of test
NO
The measurement value is not OK.Possible cause and remedy
- N10/1f43 (Fuse 43)
- Cable for voltage supply
End of test
2. Check component B28 (Pressure sensor).
Test 2.1: Check component B28 (Pressure sensor) using actual value.
Test 2.2: Check power supply of component B28 (Pressure sensor).
Test 2.3: Test signal voltage of component B28 (Pressure sensor).
2.1. Check component B28 (Pressure sensor) using actual value.
Test sequence
- Switch on ignition.
Status of relevant actual value:
- Coolant temperature:Warning! Communication with ECU required.
- Intake manifold pressure (ADC):Warning! Communication with ECU required.
Specified values
- Coolant temperature > 80锟斤拷 C
- Intake manifold pressure,Ignition ON: > 3.5 V
- Intake manifold pressure,Operate engine at idling speed.:< 2 V
Question
- Is the actual value o.k.?
