Question about Volkswagen New Beetle
Hi, since you have the technical ability on how to troubleshoot and fix the car, i will just give you some basic points about the MAF Connector which will guide you through on what to do next.
If MAF output is stuck at 12vdc so it is blow out. If the MAFoutput is stuck over 1.7-2.0 volts AT 800 RPM, then the MAF is bad ,but the RPM must be 800. If the MAF output will not advance above 2v while raising the RPM then it is dead. If the MAF output is stuck at 5v, or 4.75 volt are near maximum , all the time , it is bad. If the MAFoutput is **** below 1.0 Key at key on , not started ,it is bad. If the MAF ground pin is not 0.5v or lower , then your ground is bad, repair wires. if the MAF power pin does not read the same as the battery voltage 12.6v , then you have a power failure. The ECU uses this same power.
If there is no voltage, or the voltage is out of range, replace the MAF sensor.
