Also, is there any signs of bad harness insulation anywhere??
..and lastly, take your V meter and give me a V reading at pin #2 of the 38 pin connector ... meters + to pin 2 and - to engine ground w/key ON.
No jumpers or anything like that..I just want a reading ...
Also , did you clear the codes after replacing the relay and did the new relay have any V rating.?

Arthur,
Hi!
I. Relay Voltage: As to the different voltage readings, this is absoulutely true: With engine on - sockets for relay pins 85 & 86: yesterday I got 12 volts, today I get 4.5 volts.
II. Wiring: My engine harness is less than 12 months and 5,000 months old. About 2 weeks ago I replaced the harness that transmits signals from oil temp and pressure sensors (and 1 other sensor). I replace this because there was significant insulation breakdown.
I've looked at just about every other wire on the car - they look ok.
III. Pin 2 of 38 pin socket: 12 volts (I grounded in socket 1 of 8 pin socket - fyi). Key on, engine NOT running.
1V. Code Clearing: Yes. I actually cleared both codes last night in anticipation of receiving relay. Codes return in normal fashion (3 ignition cycles). I cleared them again.
V. Relay voltage: Just like the original - the replacement is rated 12 volts. This is stamped on the cover.
******
Having said all of the above - something I've never mentioned: While the relay has 5 pins, the relay receptacle only has 4 live female sockets. The extra pin is labeled 87a (possibly a for "auxillary" - as there is a live socket for pin 87 (just the number without "a").
Well, thats the info you asked for. I really appreciate your help. Because I'm stumped, frankly.
Thanks!
Jim
