These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

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

  • Planet-9: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1Original post

Being an old-school air-cooled P-car guy, I really miss oil temp and pressure in my new (to me) 2009 Cayman S . The 987.2 cars use the Siemens ECU which apparently supplies real CAN messages. In reading AiM's information, it appears that coolant temp, oil temp and oil pressure channels are all available: Code: ECU_9 SM_ECT Engine coolant temperature ECU_10 SM_OIL_T Oil temperature ECU_11 SM_OIL_P Oil pressure However, I've read that a proper oil pressure sender isn't installed on our cars -- just a low pressure switch. Can someone confirm that this is correct? By the way, the AiM data is here: http://www.aim-sportline.com/downlo...oad/ecu/stock/porsche/4_Porsche_997-987MK2OBDII+EMS_SDI-3.1_Siemens_104_eng.pdf Thanks, John

POST 2Original post

I believe you need to install a 911 dual sender ( and a gauge for good luck ) and run a wire to the ECU for oil pressure. Oil temperature comes from the existing oil level/temp sensor.

POST 3Original post

Thanks Rob. Do you mean a pressure sender that has a regular variable pressure output as well as a low pressure warning output? Any ideas on where/how to connect the variable output to the ECU ?

POST 4Original post

John, he is referring to part number 996-606-203-02. It has two terminal spades instead of the one on our current oil pressure sender. The "extra" one would connect to a gage.

POST 5Original post

Oil pressure is available in 987.2 via CAN bus and AiM Solo DL. Here are some data traces.

POST 6Original post

Thank you very much, sir! That confirms what I was hoping. It would appear that the 987.2 's (at least the S and R) have a real oil pressure sender and not just a switch. It looks like the AIM information confirms that. http://www.planet-9.com/987-cayman-...7-cayman-boxster-competition/83372-aim-solo-dl-lap-timer-data-logger-987-a.html http://www.planet-9.com/attachments...25078-aim-solo-dl-lap-timer-data-logger-987-porsche-data-channel-comparison.pdf I'm not planning on tracking the car so an AIM system is probably overkill. I bought a couple of OBDII/CAN bluetooth readers and we'll see whether I can get oil temp/pressure on my phone before I go further.

POST 7Original post

Would be great to get this info into the multi instrument. But sense nobody ever tried this?

POST 8Original post

Can you get the AIM Solo DL with CAN bus to show real time oil pressure and temp? Or only on a tracing when you download the data?

POST 10Original post

Aim canbus data definitely shows real time oil pressure and temp. I've used it for over a year now in my Cayman . Sent from my iPhone using Tapatalk

POST 11Original post

Thanks for the response! Is it an easy plug and play or is it hardwired?

POST 12Original post

It is hard wired. Tapped into the 2 canbus wires. Sent from my iPhone using Tapatalk

POST 13Original post

An old thread but... Do you know the CAN PID for the oil pressure message, and how the data is formatted? And whether its the same on a 987.1 ? Jon.

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