P0501 code? - 1996 Audi A4

Take it to an Auto Zone or another auto parts store and have them run a code check

vss dead (veh, speed sensor)
A/T 700 codes are transmission errors. so is p17xxx
706 is trans mission range switch open circuited (bad switch or wires)
the scan codes never tell you what part is bad or what to replace.
it tells you ONLY what tests fail. called Monitors.
a Service tech, does this magic,. with tools and meters and gauges and special tests.
you can look up codes here.
http://engine-codes.com/

you can go to alldata.com (or get a real honda fsm book)
in the book it covers each code and now to test it and find the truth.
for example they will show you how to find P0501.
by looking at the VSS signal if good, the wires are bad.
if the signal is bad, the sender is bad. using a scope or meter.
good luck to you.

I doubt it.
Code 501 is for a problem with the speed sensor in the transmission which affects the speedometer and shifting.

The code P0501 indicates that the vehicle speed sensor (VSS) is out of range. This may be due to a bad sensor or bad or dirty wiring/connector. I'm not sure exactly where the sensor is located on the Elantra but it's on the transmission possibly around the differential housing near one of the axle shafts. Hope this help.

code p341...cyllender 1 misfire
code p1580..throttle actuator b1 malfunction
code p740.. manufacturer specific trouble code
code p0501.. vehicle speed sensor

P0700 is just to tell you there is a trans code stored . P1794 is a vehicle speed sensor problem or output speed sensor problem depending on the trans type. P0501 is a body computer code for no vehicle speed signal.I would replace the output speed sensor.

P0500 and P0501 are vehicle speed sensor codes P1529 I can not find in any of my data bases. if you are using a generic scanner/code reader it may be a false display or for some reason it's not listed in my reference materials. I have 4 different sources 1 being factory material?

P0501 Vehicle Speed Sensor Range/Performance. I believe Hyundai put their speed sensor on one of the front drive wheels, on the backing plate of the brake rotor. I suspect it to be the passenger wheel

You could possibly have a bad wheel speed sensor or broken wire or faulty connection triggering the code. The wiring and connections will run along your inner fender pannel

Buy a Bentley's or join a VW forum, surely they will have forums for DTC code description.
