That's the right answer. On the I6 engine, the displayed oil pressure is a fantasy number MADE UP by the PCM to convince the average owner that there's some life beyond the firewall. I don't know how the designer was able to sleep at night knowing the system was lying continuously like that. Management must have tied them in their chair and forced them to do the unethical thing.AbsoluteZero said:..My guess is if the oil pressure was actually displayed at 20 psi at idle there would be a flood of people complaining.
AbsoluteZero said:When first started the HF gauges will read in the high 70's and when the oil is warmed and at engine idle the oil pressure is 10-15 psi.
From what I could find the specs are 12 psi @ 1200 rpm. Agree on the accuracy of the HF gauge, especially at the end points. I would have liked to check it against a known good gauge but don't have one available. I installed it more as a curiosity factor as a check against the IP display.Mark20 said:I think its a 12 PSI switch. So 12 PSI or greater its on and less than 12 its off and that's the computer's decision point. So 10-15 is believable. I'm not going to assume HF stuff is calibrated too exactly.

People don't necessrily need to know the real PSI of their oil unless there is imminent failure about to happen. The exception if the off-road crowd who need to monitor real PSI on hill climbs and descents.
