I autotapped my car tonight because I am among many others with the infamous oil pressure drop after warmup and my oil pressure voltage says 0 constantly. Is it supposed to be like that or is my sending unit bad?
Thanks,
Wes

supposedto be like that... I dunno if our oil pressure sender doesn't send to the PCM or if the PCM doesn't support sending pressure out on the bus... but it will always appear as 0

This is quoted directly from EFI Live FAQ.
Why can't I log oil pressure on my F body?
The F-Body PCM does not provide an oil pressure PID value. The PCM software reports that the oil pressure PID is supported, however the PCM does not provide oil pressure data for that PID. The oil pressure is sent directly to the instrument gauge. The oil pressure PID has been removed from EFILive V6 for F body applications.
The Y body oil pressure PID is supported and does report oil pressure.
The GM-H Commodore oil pressure PID is supported and does report oil pressure.
