So the ecu monitors certain sensors, the MAF being the one he unplugged. This sensor, if it does not match the TPS for what the ecu wants to see for it to run efficiently it will go into a type of limp mode that ignores said MAF sensor, so when he unplugs it and it runs still rough it was already being ignored by the ecu due to problems. If it died, it means it was being monitored, and the fuel air mixture spike caused a stall out. I would not plug it back in while the engine was running. This could arch the ecu or the sensor, causing damage. You can spray clean the MAF when the sensor is cold to try and save it. Just remember to clear the code after cleaning to see if it duplicates, and if it does, it can be the sensor ( most likely ), the harness, the ecu ( least likely ).

It won't always kill the car. Some vehicles will go into a sort of "fail safe" like a limp mode. Some vehicles, like my 08 Pontiac G6, will (with it unplugged) use the throttle position sensor and the true throttle position to assume the fuel air mixture. This is NOT a definitive test.

Un-plugging your MAF sensor doesn't prove it failing only a big leak in your vacuum system would cause your vehicle to shut off, a small leak will cause this vehicle to keep running because other sensors and your PCM would compensate for the disconnected MAF sensor.

What I am sure work for all cars is that once you unplug the connector and start hearing your engine hesitate or stop, the Maf sensor is working for sure. To confirm if the sensor is working optimally though you should to a DTC scan.

These are the codes pulled while maf is unplugged Of course the maf code Auxiliary coolant pump relay Fuel pressure regulatory valve ( open circuit/ short to ground) Supply relay for engine components ( electrical error in circuits) Secondary air injection pump relay ( short to ground) And cooling fan 1 control circuit I'm doing injectors (because I rushed and bought them thinking that was the problem but doubt it now) and carbon cleaning this weekend/ today... My wife has the same car as me.. 2012 beetle turbo 2.0tsi e888 Gen 1 cbfa... hers is still stock, mine is fbo ko4 turbo and uni tuned. I'm going to start with switching relays ... (better than buying them and waste money if I don't need them) I've already spent $370 for a oem maf and 400$ for injectors, seals,and intake manifold gasket... I'm going to try to find the problem b4 I do my injectors and carbon cleaning.. if it not a relay then next will be my upstream o2 (downstream is tuned out because 200cell catted dp) After that, I'll check my fuel pumps lpfp and hpfp.. And if that's not the problem, I give up🤷♂️🤣

@awelsemense what's crazy is I drove the car fine.. I even raced a 5.7 charger ( put busses on him) on the way to my chiropractor apartment... Backed into my parking space idled for about a minute (help cool the turbo off) then shut it off Come out 30 minutes later.. start the car and it dies... no signs or symptoms of anything...

It'd normal that engine showing on dash once you disconnect the harness connection to eliminate the light on dash disconnect the negative battery terminal maybe 10 minutes then light on dash disappear.if not insert scanner and delete the light.Your Maf sensor that's still ok.Kasi di lahat ng sasakayan ma off siiya once you disconnect ok
