Check Engine Code 13...
 
So my check engine light comes on when I get on the gas in my S5 N/A.

I just checked the codes and it read "13"... I looked it up and it's the intake manifold pressure.

1300cc.com says it's caused by a "broken wire or short circuit" and that the "intake pressure is fixed at 760 mmHg (29.9 inhg)" as the fail safe.

I don't know what unit of measure that is, or how much of a problem this is.

Can anyone help me fix it?

iluvmyrx7.com no longer seems to be in business, otherwise I would consult the FSM... perhaps someone has access to it?

bump... no one has ever had this?

It is most likely the pressure sensor itself. This is a very important compnent it tells the ECU what vacuum the engine is seeing. I have a few spare N350 sensors if you find out that yours is bad. Check to make sure the vacuum hose is still connected to the manifold and to the sensor.

a code is set when there is an open or short in the circuit. and some sensors like the tps, are set when the value is out of range. make sure the pressure sensor, is hooked up, both electrically and with vacuum

Appreciate it, but a friend of mine locally has one.

None of the hoses or wires look damaged or disconnected, so it looks like it's the sensor itself.

Would everyone strongly recommend against driving it this way?
