Caudalímetro: Sensor de flujo de aire. Detecta cuánto aire está ingresando al motor.
Leer más
Mide la masa de aire y sirve a la ECU para poder calcular exactamente cuánto oxígeno está ingresando al motor. Con esa información la ECU regula los parámetros del motor para asegurar en una correcta performance. El Sensor está ubicado en el conducto de admisión, antes del cuerpo de mariposa.
Buenas gente,espero puedan darme una mano... Compre una Amarok 2011 163hp, siempre la note media lerda ,como sin fuerza (desde las 1000 a 2300RPM ,despues de las 2300 va cañon) la hice escanear y me salta solamente un error, el P0101 que es del MAF. Se lo cambie x uno nuevo y sigue lenta. No pasa los 140km/h ,NO PRENDE EL RULO DE PRECALENTAMIENTO,anda perfecta ,no falla,no humea,solo esta lenta comparadas con las otras... aclaro que tambien anule EGR ,cambie el sensor MAP tambien. Controlaron el punto tambien. Esta todo ok. Espero me ayuden saludos...
Hola controlaron el sensor maf que no este en corto? de donde sos? yo trabajo en VW OFICIAL tengo el escaner oficial te dejo mi mail por si no lo solucionastes
I need some advise from members since have done alot on the car but still nothing...the car starts well and has good engine sound but doesn't pull...have replaced the high pressure pump, fuel filter, inyector nozzles, cleaned the egr, unblocked the exhaust, worked on the turbo cartridges, changed the MAF, changed the MAP, cleaned and replaced the throttle, literally have done almost everything but no progress yet. Have also changed the intake and exhaust valves.
Hello Josef Karz. We see that you have decided to replace a lot of parts, maybe they needed changing or not, but that way is more or less like shooting a partridge on the fly, with some pellet we could hit it. If the resource is available , well and good , but if it is not , in the end the owner 's account will be somewhat bulky. If it helps you, I'll share with you what we do in a similar case. When an engine does not perform and we do not have a before of how it was, the first thing to do is take the compression pressure and make sure it is 27.5 kg/cm2 and no more than 10% between cylinders. If that is so , you can surely get an engine that shines. The second thing to look at is where the engine sits in its air/fuel ratio. To see how much air your engine is processing, with the help of a VCDS or other equipment that works with the VW platform, select theoretical air mass / actual air mass, target turbo pressure / actual turbo pressure and you observe in these variables that divergences exist. If the biturbo at a high load (100%) reaches 2.8 maximum 3 bars of absolute pressure, the turbos will be well calibrated. If this is so on the MAF side you should get about 1300/1400 m gr/stroke at that time, with a lag of no more than 0.5 seconds. On the fuel side it is something similar. You select target rail pressure/actual rail pressure and see what divergence there is in these values. If you can record these events and send us a copy, we can be more assertive in collaborating to solve your problem. Cheers
