I'm getting DTC P1101 intermittently. Any ideas what this is?

I figured it out. It was connected to the intake/vaccum hose on the top by the plenum. Not sure what sensor it is, but it's hidden....

Here's the picture

Installing the plenum in a 996TT. Almost got everything put back but I realized there was a connector I unplugged and can't find where it connects to.

It the harness in the engine bay that connects to throttle body, Air Intake temp, Oil temp sensor, and not sure what the last one is?? It's got a metal clip that you have to push in to get out. Where does this connect to?

Can anyone identify?

Thanks.

I'm upgrading to the 75mm plenum and need a 75mm throttle body =)

The porsche dealer doesn't know what size these are.

997-605-116-00 is the X51 part.

I don't know if that will fit a standard distributor tube - the X51 gets a different one of those too.

What are you trying to do?

Did you check for boost leaks? If the sound you hear isn't the engine or muffler, it could be air escaping. If your boost is steady (low) or starts to decrease, it could be a boost leak. At a certain point, the engine will make more air than it leaks out and boost will start to build again. You should get a real boost gauge with memory function so you can review the boost curve afterwards.

I had similar problem and found out later that my boost hose was leaking -- the end cap started to come off the rubber hose.

I have a problem “doubt” with some changes I made on my car, it is a 996TT with Gemballa tunning (550 HP) , K24 turbos. I was getting with OEM waste gates 0,9 boost smoothly on all gears, now I did some changes :

1. Installed new Plenum from Automotion (performance parts) with 75mm TB

2. New Air System from EVO

3. New waste gate kit from EVO

Now as a result I have a setup of 1,0 boost but the strange thing is I go to 0,4 boost directly when I press on gas until aprox 3500 rpm, at that point I hear a roaring sound and it launches the car to 1,0 boost .

My question is if this is right or I can damage the car that way, I got information from a fellow member that with the K24 turbos he was getting 1,2 boost at 3000 rpm

This is his result:

If i can tell you my experience, when you will have 1,3 bar at 3000-3500 RPM, 1,1-1,2 from 3500 to 5000 rpm, and again 1,2 at 6000 rpm with some peaks of 1,3 in the last rpm, with original internal engine parts, your car is near to be perfect.

Should I rise boost or what suggest are out there?

Anyone have a 997NA 75mm throttle body part number?

The porsche dealer says there's 2 part number 997-605-115-01 (Standard) and 997-605-116-00 (power pack)

Not sure the differences and which is the 75mm part.

Does anyone know the torque spec for the 4 bolts that attaches the throttle body to the Plenum? Also is there a specific torque sequence?

Thanks.

On a MY05 Turbo S the easiest place to get it is the Violet/Green wire that goes to the OBD II (diagnostic plug).

Loren,

Is this the same for 01 TT?

Sweet! Much better than the standard tip buttons. How much did it cost?

It's the crank sensor.

Thanks Loren I didn't receive the email.

But it is vacuum that's needed. The company said the fuel pressure regulator is where they usually tap, but they have never had a unit installed on a TT

Anyone have a picture/description of where to TAP the vaccum line for a boost gauge?

Do we have to reprogram the DME for the 996 if we change from 124 to the 125?

I do not see a TSB listed for the 996 regarding the Air Flow Sensor. When I called the dealer to ask, they were not aware of one and he said it would be automatically calibrated after about 1 hour of driving.

KC, I think you need to reread the thread (or maybe I do :) ). You both have egas cars so, if my reading of this thread is correct, and if you replace a older 124 with a newer 125 MAF sensor you will need to get the DME reprogrammed.

You might get lucky and be able to get the 124 part but I'll be surprised if it is available for much longer.

Guys, sorry my mistake. The stock one is 124 part number.

I ordered the 125.01 and it seems fine so far - no CEL lights.

Help. I ordered a 996TT MAF online and they sent me this part number 986-606-125-01. Will it work on a 996TT or do I need to return it?

The original part was 996-606-123-00.

Help appreciated.

Thanks!
