Tiptronic D-4 flashing, P0710, Not in limp mode.

[NewArt1]

Lately my 2001 Boxster S tiptronic has been throwing a P0710 code. This is indicated first by my transmission selector lights flashing alternately between D and 4. Otherwise the transmission behaves normally, shifting up and down, in both auto and manual modes. Information on this is sketchy. My durametric tells me that the code (P0710) is a Transmission temperature sensor fault. I would first like to check the sensor, a procedure which is briefly outlined in a repair manual ("Check sender for ATF temperature with wiring. To do this connect an ohmmeter to control module connector pins 21 and 22...etc.) Now there's a box in my rear trunk that's supposed to be the control unit but where exactly are the connector pins 21 and 22 located? Sorry if I seem a bit dense here. :unsure:

Step 1 - Check and top up ATF level.

Check for leaks while you are at it.

Thanks, I'll check that. BTW my car's last home was in Roseville. Ron Kain at IPB Autosport did the PPI.

Seems that the fluid is okay. It was replaced in the spring. It may be the sensor. Had a hard time finding the right part number. Apparently you have to replace the whole wiring harness. The part is 4 hundred and change at Porsche, I found an OEM for 170. I'll try to figure out the electrical troubleshooting procedure first.
