I have a 01dodge RAM 1500 and the oil gauge keeps going from 40 to 0 and the check gauges light keeps coming on but I checked the oil and it's fine, what could be the reason for this

1. You need to have an independent oil pressure gauge hooked up to the engine to check the oil pressures at various RPMs and to verify the 40 to zero drop. This will eliminate any issue with the pressure gauge or the sending unit.

2. The oil pressure variation can be caused by an intermittent blockage in the oil pick up or an intermittent sticking oil pressure relief valve. I would possibly suspect the latter if you are getting good pressure and it is intermittently dropping to zero and going back up again..
If you or previous owners have not maintained the engine with frequent oil changes you will get a sludge build up problem in the engine and this will be evident by just dropping the engine sump.

3. If you have had a check engine light warning then you need to have the vehicle scanned to see what fault codes have been generated by the computer. There will be some related to the intermittent loss of oil pressure but there may be others also..

4. You need to have the oil pressure problem checked out immediately. Running the engine when you constantly lose oil pressure intermittently will definitely cause engine damage due to a loss of both lubrication and oil cooling to critical components.

Start intermittly

check engine light??if so then better bring it to the expert and try diagnostic scan to retrieve the fault code..if check engine doesnt light..try check your fuel pump pressure,might low pressured fuel or high pressured due to malfunctioned pressure regulator sensor..

Intermittant low oil pressure jaguar x300

Install mechanical oil pressure gauge,verify that low oil pressure is indeed intermittent or not.if yes suggests oil pick-up screen possibly clogged,excessive pump or bearing wear,if not faulty sender and/or wiring would prove to be the culprit.

DTC Code P0107

Continuous diagnostic trouble code P0107 indicated barometric pressure out of range low was detected during normal operation.

Possible cause
- faulty internal BARO sensor (PCM)

Perform KOEO On-Demand Self Test.
Is P0107 present?
No, P0107 is intermittent fault. CLEAR DTC. If DTC reappears, REPLACE PCM.

If you keep getting it, a new PCM is the only fix.

The check gages light comes on and off while driving, at the same time, the oil pressure gage drops and then bounces back up after hitting zero

There a couple of possibilities; you could have an intermittent oil pressure switch or an intermittent stepper motor in the instrument cluster. The stepper motor drives the gauge.

Some days the car will not start checked fuel pressure and sometimes it has pressure and sometimes not. does that mean it is a bad fuel pump?

Yes it does it means its intermittent,by being intermittent it works then it doesnt work.also when you replace fuel pump or going to rplace the pump do a fuel filter

Intermittant pressure

I'm a little confused. You have a chain saw with "intermittent pressure"? If you could give us a little more information we would be happy to try and help.

With the water running the MQ pump runs intermittently

This is a problem with your bladder in the pressure tank or the pressure switch. Ether one will produce this cycling on and off. Good luck.

A/C is intermittent. How do I check the wiring on the A/C panel? It looks like you have to take the whole car apart!

An intermittent a/c is usually b/c of low pressure. I would have a licenses mechanic check it for leaks, and check the pressure levels. You will need a gage tree to check the pressure levels in the a/c.
