Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Is this the same thing as a throttle position sensor?

POST 3 / ORIGINAL POSTEROriginal post

Awesome. Thx! Grabbing it off the DME at the same time as the oil temp sensor. When I get some higher values for the oil temp this weekend I will post them to your thread.

POST 4Original post

Pin 44 "TV-signal" of the DME? Oil temp is pin 73 of the DME. Yeah, let me know what oil temp you see. One potential issue with the stock oil sensor is it sits ~1" above the oil sump bottom, on the right side (bank 2) of the engine and OUTSIDE the plastic oil baffle of the sump. So it's perceivable with extreme g-force (e.g., hard and long right turns), it could be starved of engine oil. If that happens, I think we should see pretty sharp oil temp drop (crankcase air temp) though. This may also explain what Jake saw.

POST 5 / ORIGINAL POSTEROriginal post

I'll be able to log it at 10Hz and should be able to tell if that happens and correlate it to the g-force.

POST 6 / ORIGINAL POSTEROriginal post

And yes, I'm tapping into the TV. Haha!

POST 8Original post

BTW, from the Porsche oil temp sensor tolerance curve, at the range of interest (100C to 150C), the error is about +/- 5 degrees C (or +/- 10 degrees F).

This is a source reference. Confirm exact model applicability in the original material.
