Have you change the oil pressure sending unit, that's what I had to do.

Definition of a compound gauge?

A compound gauge is a pressure gauge that displays both negative and positive gauge pressure measurements. Gauge pressure is a measurement of pressure relative to ambient pressure. For example, if ambient pressure was 14.7 PSI and you were to measure absolute vaccum using a compound gauge, the gauge would indicate -14.7 PSI.

What type of gauge would you use to check fuel pressure?

I use a fuel pressure gauge.

Why would my 1995 4.3L'V6 GMC SOMONA have no oil pressure?

1. low oil 2. electronic oil pressure switch has failed (probably not a mechanical oil pressure gauge cause then you would see a oil line running through the firewall to the gauge. 3. short in the wiring

What would cause loss of oil pressure in 1996 F150?

Worn crankshaft bearings, oil pump, or a defective oil pressure sending unit. Have a oil pressure test done with a mechanical gauge, the electric gauge is not very accurate and is prone too failure.

What is vacuum gauge pressure?

Gauge pressure usually refers to the pressure difference between ambient, atmospheric pressure and the pressure in a vessel or line. A gauge pressure of zero would mean that the vessel or line was at atmospheric pressure. Normally the pressures of interest are ABOVE atmospheric so the gauge pressure is positive. Vacuum gauge pressure measures how far BELOW atmospheric pressure a vessel or line is. As such vacuum gauge pressure may be measured as a negative number - or for convenience it may be reported as a positive number with the caveat that it is "vacuum gauge pressure", meaning that the reported pressure is how far atmospheric pressure is above the pressure in the vessel or line.

If the absolute pressure of gas is 550.280 kPa it Gage pressure is?

The gauge pressure would be 448.955kPa.

What would cause the engine oil pressure gauge to rise?

My 89 4.0 engine had this problem every couple of years. The pressure gauge on the dash would peg out on high on the scale. It was always the oil pressure sensor located right below the distributer. Yours might be different. Not expensive. You might be able to do it your self.

What would cause your oil pressure gauge to go down to the red line at idle and back up when driving I'm thinking oil pump oil pressure sensor or the gauge?

sounds like the cam bearings may be going bad

How do you detect leak in a vacuum chamber?

The simplest method would be to mount a pressure gauge onto the chamber, then to observe whether the reading changes. It should remain at "zero" indicated gauge pressure. If your instrumentation is relative to atmospheric pressure, it would be a "minus" pressure and would vary with local atmospheric pressure. For very accurate readings, you would need something more sophisticated, such as an ionisation gauge.

If the absolute pressure of a gas is 550.280 kPa its gage pressure is?

The gauge pressure would be 448.955 kPa.

Why would your oil pressure sensor register no pressure if the car is running fine?

Many sending units do not have continuity below 6-7psi. This would cause the gauge to read nothing and indicate a base engine problem. Some type of engine noise would be associated with this concern (ie. ticking, rattling). The sending unit or wire to the gauge could be open. This would be an electrical problem and have nothing to do with the engine. Along that same line would be a defective gauge.

How do you know if your house is high or low water pressure?

I Guess the easiest way would to buy a gauge place it on a hose bib connection and then read what the gauge pressure is

What problem would you have if your 1992 Chevrolet Cheyenne 1500 is not getting enough gas to keep it idling?

Need to check fuel pressure with a gauge first. Then check fuel pressure regulator. Need to check fuel pressure with a gauge first. Then check fuel pressure regulator. Need to check fuel pressure with a gauge first. Then check fuel pressure regulator. Need to check fuel pressure with a gauge first. Then check fuel pressure regulator.

What would cause my gas gauge not to work in my 1994 Ford Aspire?

A common cause for a gas gauge to stop working in a 1994 Ford Aspire is a defective fuel gauge. Lose wiring in the dash is another cause.

What would cause the oil pressure gauge to turn off on a 1994 Buick Skylark?

A lack of oil in the engine./ the sensor in the oil system./ broken oil pump

What would cause the oil pressure gauge to go up and down in 1998 dodge ram 1500?

-faulty oil pres. sending unit -faulty oil pump

What would cause oil pressure to drop when idling in 2000 jeep wrangler?

Depending on mileage--could just be a sign of engine wear Remove oil sending unit and replace with mechanical gauge to determine actual pressure

What would cause the fuel gauge on a 1993 Ford Thunderbird to stay on full all the time?

A potential bad gauge or sender unit in the tank would cause it to read full all the time.

What is the cause for your 97 Checy Tahoe LT oil pressure gauge fluctuating constantly and idle is not staying constant Idle revs when in Neutral?

probably a leak in the intake would cause the rev in neutral and as for the oil pressure gauge i still haven't got that figured out but its not just a problem on tahoes i have a 2500 pickup which also does that ANSWER When was the last time you changed the oil engine?. Replace and check.

92 Chevy replace oil pump?

what would cause a oil pressure gauge to fluctuate on my 99 Chevy truck silverado i change the sending unit it does it mostly after it warmed up

Is it possible for the oil filter gasket to blow on a Chrysler spirit and would the oil pump be the cause of it?

Yes, both are possible, you need to check oil pressure with a mechanical gauge. If pressure is over 80 psi then the oil pump is bad.

What is the instrument that indicates engine power for an aircraft with a fixed-pitch propeller?

That would be the RPM gauge. On an aircraft with variable pitch prop it would be the manifold pressure gauge.

Does diarrhea cause high blood pressure?

Usually it would cause low blood pressure from dehydration and hypovolemia.

On a 1996 Grand Cherokee Laredo What would cause the oil pressure gauge to fall all the way to zero when coming to a complete stop and having the check gauges light come on then returning to normal?

Loose wire, bad pressure sender (common), low oil pressure.

How does barometric pressure affect gauge pressure?

Assuming we are using a pressure transducer to measure barometric pressure, I understand that a gauge type transducer would be used. The internal diaphragm would have a fixed pressure behind it (at a guess would be at standard temp/pressure, STP, ie 20 deg C @ 1013mb), so the transducer has a reference to work against. The front of the diaphragm would be exposed to atmosphere. I would assume the reference (gauge) pressure would vary as the barometric pressure varies, as the diaphragm would move towards the side with least pressure, or at 1013mb the diapragm would be in the centre (which could be used as the null output voltage), higher than 1013mb could produce a positive voltage swing, less than 1013mb could go negative. This is all I can think of, please let me know if on the right track.
