Error Code T107


Recommended Posts

Hellp Please,

Just the other day I started getting a hiccup/ hesitation in my 996.

First noticed it when I started the car, it typically idles at about 1200 RPM's cold start, however this morning it was at 850 or 900. After 1 minute it was still a bit rough at 750 RPMs.

When we started driving I had to press the accelerator a little more than usual. We jump onto the highway ramp and in 2nd :drive: gear floored it at 3900 to 4100 RPM’s BURP BURP and :cursing: then smoothed out up to 7K hit 3rd :drive: gear and right at 3800 to 4200

RPM’s same thing like I took my foot of the gas and then floored it again .

As soon as I got home I jumped onto RENNTECH and looked for similar issues, found some like possible, Mass air flow sensor, miss fire in spark plug / wire issue etc.

I took it over to the Porsche Dealer and had them run diagnostics on it. They said the error was: ERROR CODE: T107 "ambient pressure plausible signal" Then they proceeded to tell me I needed a new DMA which would cost $2,700 :angry: complete with labor.

I told them nope not yet, and decided to get a second, 3rd and 4th opinion. It seems like every time I take the car to them they see the $/ goof tattoo on my forehead.

Any assistance or recommendations would be really appreciated!!! Thanks

Thanks Loren

When you say the sensor is inside of the DME for my understanding just were is it located in the car? I ask due to your comment of water intrusion, is this in engine compartment?

And if it has sustained damage would I need to replace a part of a sensor or whole DME? Dealer says I need complete new DME
