Oil Pressure

[FlyingMonkey]

If you give me the instrument make and model, I can look up the manual for this part and tell you which pins go where.

 

I'll have to look at at the gauge next time I'm at the hangar.

New sender did not cure the problem. We pulled the right panel yesterday and confirmed everything was well connected to the ground block. We found the wire for oil pressure on the back of the gauges and reseated the bayonet connector. No change. I'm wondering if I might have a second failed gauge, since this is similar to behavior that was fixed with a new gauge last time...

VDO oil pressure sender part no. V360 003 (5 bar) is to be matched to VDO oil pressure gauge

 

 

V350 040 (0 - 80 PSI).

 

 

VDO oil pressure sender part no. V360 004 (10 bar) is to be matched to VDO oil pressure gauge

 

 

V350 041 (0 - 150 PSI).

 

 

The quickest way to identify whether or not your engine has the correct pressure gauge and

 

 

corresponding sending unit is to visually verify the 0 - 5 bar or 0 - 10 bar stamped on the sending

 

 

unit hex nut (see Figure 1) and assure such is matched to its corresponding 0

Andy, I believe we have been dealing with "spurious" voltage with our puzzling "rpm rollback" issue.   We are finding that there probably was (is?) a 12v. bleed into the module soft start wiring.  We aren't sure how this occurs but think this may be caused by loose or poor wiring at the ignition switch.  I am posting this update tonight on the "RPM Rollback" thread.  Perhaps you are getting a "bleed thru" of voltage too which is causing your oil pressure to act weird?
