Resistance value for the MAF

[t_marat]

What is the resistance value of the MAF sensor for the M50TU engine? It is a hot film mass air flow sensor. Bentley lists the resistance value only for the M50 engine with hot wire sensor.
I think mine is dead as it is obvious somebody seems to have openned it before. But would like to be sure. I checked the voltage in the connector and I get about 12,30Volts in some of the pins.

Also, my thorttle position sensor resistance reads a range of 1,36Kohms to 4,22Kohms. Fine? Bentley gives values of 1-4Kohms but says it is approximate.

I have a 1995 E34/M50TU and a Fluke DVM. Tell me exactly where (which connectors and pins) you are measuring and I'll try to get you some values to compare.

Now I wonder what the differences will be between the nice, expensive and very accurate FLUKE and t-marat's big investment for his DVV

I bought one locally. Paid 3.2$!
DCV: 200mV-100V
ACV: 200, 750
Amperage: 200microA - 10A
Resistance: 200Ohms - 2MOhms
No measurement range for capacitors.
Guess more than enough
Wonder if someday China will start producing goods for free

Yes, my next target is a FLUKE

MAF is located just after the air filter box. It has a connector which is screwed into it. There are 4 pins. I have no idea which pins I should measure. But if you take general measurements and tell me the values I would be more than happy.

Picture of my MAF, obvious somebody openned it and tried to seal it back.
Anybody could advise me the resistance values? I measured something like 0.6-0.7 Ohms through right upper and lower pins. Other two pins does not seem to have any kind of circuit.

I think Danzee wants you to measure between arbitrary pins of your choice and give him the values for comparison...

Time to clean that bay dude!

Ya I know. But the climate at where I live is extremely dusty.

Anybody can help me with the resistance value of the MAF? That thing is extremely expensive, about 400Euros for a new one!

When I unplug it while the engine is running, I see absolute no difference in idle quality. None at all. Tried disconnecting the battery for 2 hours (to reset the DME) and doing it again, no difference in idle again. Can I presume the MAF to be dead?
