G71 sensor

Anyone know what sensor this is? Fault code on rs2.
Thanks

00519 2222 Manifold Absolute Pressure Sensor, G71
- Signal too low

- Signal too high

- Control difference
Vacuum line between inlet manifold and J220 pinched, plugged or constricted/bent

Fluid separator in tube from inlet manifold to J220 full of water

Wastegate faulty

Wastegate frequency valve faulty

MAP sensor in J220 faulty

Turbocharger faulty
Loss of power
Check vacuum tube and fluid separator

Check wastegate and frequency valve

Check turbocharger

I had the same code BTW Sal when there was no MAP sensor in the ECU!

[sal_s2]

Nice one Jamo.
What is the solenoid near the ecu with the vacuum piupes for? AC? Should it have anything to do with the ecu vacuum pipe?

[Jamo]

That came up before recently and I can't remember the answer mate.

The ecu vacuum pipe should have a filter on it then straight run through the bulkhead IIRC.

[sal_s2]

This one was connected to that solenoid which I've never come across before.
Normally theyre just connected to that water trap then straight through the bulkhead.
Also normally the plastic pipe is green but on this one its black.

I think you are talking about the altitude adjuster but might be wrong, has a 3 pin plug going into it? pt no. 853 919 562? sits behind the outer kick panel infront of the n/s door?

[sal_s2]

No, the alt sensor is in the a post. I've bypassed the solenoid now and the car is running perfect. I'm pretty sure its for the ac

Thanks

can someone pin point me to the water trap mentioned on the G71 fault table? i a friend is experiencing this fault on his rs2 without anything else

Follow the vacuum hose from the ECU (MAP sensor) and the moisture trap shouldn't be far away.

[A80Avant]

so that is in the car then?

[A80Avant]

and what happens if you dont have this? im pretty sure mine doesnt have such a thing..

[4WheelDrifter]

It's in the footwell with the ECU. I'm not sure what happens if you don't have it. I guess the MAP sensor doesn't like moisture.

[A80Avant]

hmmmm should i get one then? i dont think the car ever had one...
