harry yarnell Posted June 8, 2002 Share Posted June 8, 2002 This is a common failure of the pressure sensor. About $30. Link to comment Share on other sites More sharing options...
Guest joereatta Posted June 10, 2002 Share Posted June 10, 2002 I have the same problem, erratic pressure never below half way but jumps to max for no apparent reason. Cause? Pressure sensor? Located where? Is replacement a do it yourself job? Link to comment Share on other sites More sharing options...
harry yarnell Posted June 10, 2002 Share Posted June 10, 2002 Pressure sensor is small vertical cylinder device above the oil filter. Has 4 pin wiring connector on top. Easy to remove, but takes a 1" (I think) open end wrench to remove. A Cresent could be used, but there isn't much room to maneuver. Link to comment Share on other sites More sharing options...
Guest Ranger Posted June 10, 2002 Share Posted June 10, 2002 My '90 tops out at high at speeds, it varies between "1/2 and full" depending on the RPM, I'd think if yours moves according to engine speeds and comes within a couple of hash marks of high at speed, you're OK?<BR>Jim Link to comment Share on other sites More sharing options...
padgett Posted June 10, 2002 Share Posted June 10, 2002 Also with the newer oil pressure sender (black plastic body) be careful about side pressure, is very easy to pop the plastic housing and gutz off the metal base.<P>Also overtightening can lead to failure, about like a spark plug works for me.

Guest joereatta Posted June 11, 2002 Share Posted June 11, 2002 my guage does not seem to be related to rpm's although I do notice it as I am cruising 70 or so on the highway but I think that is when I have the time to observe it.. i would almost think that it spikes with bumps in the road, or so it seems. Possible? Link to comment Share on other sites More sharing options...
Reatta_Cruzin Posted June 11, 2002 Share Posted June 11, 2002 I paid around $30 for a delco replacement and fixed the problem. Link to comment Share on other sites More sharing options...
