Oil temp sensor on the Y-Body feeds PCM pin D26. It's a resistor type of sensor one side to sensor ground and the other to pin D26. Probably no wire in the F-Body. It's a one byte field in the PCM log file, however the question would be " does the F-Body PCM software update and maintain the validity of that byte" It displays at -34* F on Datamaster so the byte of data in memory may be '00' . Theoretically if the F-Body code maintains integrity and updating of that byte, with a known signal and a Datamaster OR TunerPro RT hack it could be possible to log it. If it needs Y-Body code to maintain the byte the that's a big problem. Right now the line (D26) s/b floating at +5V (my guess) test would be to ground it and see if PCM displays high temp I believe it would be about 347*F as that's what the TunerPro .adx file is saying (-40 to 347 is the swing). Some good PCM knowledge over here, but it's geared to TunerPro RT GM EFI Systems
