Question about 2001 Volkswagen Passat
I got a 2001 vw passat and has engine code p1177 fuel air metering. the car seems to run fine but id like to fix this problem. is it a sensor i can fix myself?
This code can be a sensor code but the real task is to find out why the code was set in the first place. Is the sensor malfunctioning or is there something else that is causing the sensor to give erratic readings. We had this same code on a Passat that was brought into our shop, go here to read our confirmed fix.

Tips for a great answer:
engine and the automatic transmission (transmission control is only
for automatics, engine is still computer controlled no matter the
transmission type) in this vehicle are computer controlled and in
most cases when a fault occurs a fault code is stored in the memory
of the computer control module. There are exception to this, such as
the Mass Airflow Meter and fuel pressure problems. What must be done
is to have all the basic testing done such as a scan of the system
for fault codes as well as a check with a live data scanner tool for
engine functions that are not within range of normal, a trained
technician is required to know what is correct and what isn't, then
based on careful diagnostics done from a factory repair manual the
correct part is replaced or the wiring repaired or the computer
replaced (known as the PCM), which is very rarely the problem. Other
basic checks must be done as well such as mechanical problems with
the engine as well as engine state of tune and mileage on the engine.
The transmission can have mechanical issues as well such as no gear
engagement at all or a failed pump or other pressure related
