Ha- g-wagon maf plug has 3 wires
-5v power
- "-" terminal
- and I guess communication wire

I've put 22kohm, 0.25w resistor between power and communication terminals on the plug - but error p1401 persists. Btwinitial p1404 disappeared. Simple wire between these terminals makes same error. Btw the initial error is p1404 but transducer is not an issue. I changed it and havent noticed any difference. Thus I guess maf sensor is an issue which leads to limp mode. So I want to make ecu ignoring maf. There is no issue with this mod in Russia as ecological standard allow even much older cars to be used.
