YES



The actual value is okay.Further possible causes of fault



- Check internal resistance of component B2/5b1 (Intake air temperature sensor).



NO



The actual value is not o.k.Possible cause and remedy



- Signal wire



End of test



1.2.3. Check internal resistance of component B2/5b1 (Intake air temperature sensor).



Test sequence



- Switch off ignition.



- Detach coupling at component B2/5 (Hot film mass air flow sensor).



- Measure resistance with multimeter between pins (B2/5) 2 and (B2/5) 3



Specified value



- Resistor(0锟斤拷 C): [5100...5900]ohms



- Resistor(5锟斤拷 C): [4100...4800]ohms



- Resistor(10锟斤拷 C): [3300...3900]ohms



- Resistor(15锟斤拷 C): [2700...3200]ohms



- Resistor(20锟斤拷 C): [2350...2500]ohms



- Resistor(25锟斤拷 C): [1900...2100]ohms



- Resistor(30锟斤拷 C): [1600...1700]ohms



- Resistor(35锟斤拷 C): [1300...1500]ohms



- Resistor(40锟斤拷 C): [1100...1200]ohms



- Resistor(45锟斤拷 C): [920...1100]ohms



- Resistor(50锟斤拷 C): [800...900]ohms



Question



- Are the measurement values OK?
