Throttle Body & Loose Vacuum Hose

[kbrandsma]

I'm replacing my oil filler tube that leads from the trunk all the way to the engine block. The tube is actually two tubes and they connect right below the throttle body on passenger side. To get to the oil filler tube piece that mounts to the engine block, I had to remove the trottle body and the the round intake tube connected to the throttle body. I loosen the large four screw clamps and two bolts and disconnected the large intake tube from both manifolds and set them with the throttle body still attached aside.

While I was working on removing the screws that holds the oil filler tube to the block I noticed what appears to be a thin vacuum hose of some typye that was free and disconnected. The thin hose is a bit mangled and most likely will need to be replaced. I need help with two questions:

1. Anyone know the name of this tube?

and

2. Where does it connect to?

Thanks in advance.

Hello.

These Vacuum hoses are connected to the flexible rubber sleeve.

You should have 2 vacuum hoses, one on each sleeve. (see pictures)

You need to reconnect them to avoid a check engine light.

The Porsche part number seems to be like regular pipe 000 043 205 01

Good luck

Thanks for your help. Here is where it is coming from. You can see it got mangled and actually separated.

and here is where it is going to.

I purchased some vacuum tubing from Autozone and fixed the tube with a splice.

Got it all back together and threw a few CEL codes after about 50 miles. The codes are P1115, P1119, P1117 and P1121.

Any ideas?

P1115 Oxygen Sensor Heating 1 Ahead of Catalytic Converter - Below Lower Limit

P1119 Oxygen Sensor Heating 2 Ahead of Catalytic Converter - Below Lower Limit

P1117 Oxygen sensor heating 1 behind catalytic converter – below lower threshold

P1121 Oxygen sensor heating 2 behind catalytic converter – below lower threshold

Very odd that you would get all four O2 sensors with no heating. Something get disconnected?

I'll need to pop off the engine cover and take a look. Should be able to get to it on Saturday. Any ideas? It wouldn't be vacuum hoses that I spliced back together?

I also was replacing my RMS and had removed the exhaust system to drop the tranny. While I had everything disconnected I also replaced O2 sensors.

Are you sure they are the right sensors and all the wires are connected?

The O2 sensors were new Walker's 13806. The exact codes I received were P1117 and P1121. The following codes were pending P1115 and P1119.

13806 is the Bosch number (I think).

Are you sure they are properly plugged in?

Because it is acting like they are not connected.

I cleared the codes and unplugged and replugged the rear O2 sensors.

I'll drive it and see if the codes reappear, I'll get back to you!

That image of the check valve with broken plastic tube in it looks like the check valve for the Secondary Air Injection system... And im pretty sure that ONLY the Fuel Pressure Regulators plug directly into the Rubber collars that couple the Intake manifolds together.

Heres an image of the Check valve on in a parts catalog image.... I dont know where the other end of he check valve leads to cause the image doesnt show where it goes from there.

and Second is the picture of the Fuel Pressure Regulator plugged into the intake couplers.

It could be that it is hooked up correctly but you have something in your Secondary Air Injection that is faulty and is causing your o2 sensor problems.
