    i have the same problem on my 2004 hemi did you find the answer to it

    I have the same problem occasionally but from the sound of teh engine I'm pretty sure it really has pressure . I'm hoping it's a bad sending unit on the gauge.

    Ditto for me, 2004 Hemi oil pressure fluctuations and complete loss of pressure at times. Oil level is OK and engine sounds solid. I have talked to a tech and he believes it is a sensor problem.I am having it checked out soon

Had the truck the truck to the shop and they said it was the sensor. I had it replaced and it hasn't screwed up since. If you search out this problem on the net, this is a problem with engine and its oil pressure sensor. Apparently, Chrysler is aware of the problem.

Go by your nearest auto parts store and rent a mechanical oil pressure gauge. It'll cost you maybe 20 bucks. You'll have to find out where your oil pressure sensor is and unscrew it from the engine block. Install the mechanical tester and start up your truck, you'll find out if you are really getting an oil pressure reading. If you are, get a new sensor. If not...you got bigger problems, but at least you'll eliminate something.

Gauge lights


ABS and Brake warning lights intermittent may be caused by a failing wheel speed sensor(ABS Sensor) and /or its connector. You may have one on each wheel hub(4WD) or if 2WD, a sensor may be on the rear axle differential center.

Ok so I recently had my 03 dodge ram 1500 4x4 with the hemi throw a rod. I went and bought an 07 hemi with 40k on it and overhauled it. (all gaskets and seals). the rings and heads looked great on it so I...


possible issues the most important one being injector pulse width, tps and ignition/cam timing... the same block means little when whats inside is a bigger issue. You probably will need the ecm tune out of the 07 to make it work right... I can tell you that you really, REALLY need to speak with someone that has been in these shoes. I would be doing some research into the Mopar world

If I were you I would put an oil pressure gauge in place of the factory pressure sending unit, these can fail sometime when hot and cause false reading at the gauge, of the pressure seems ok replace the sender, oil viscosity can affect pressure readings but not to that extent, also check the simple things like your oil levels as these are commonly overlooked

If the valve lifters are quiet you most likely have oil pressure even with gauge showing "0".Sounds like the oil pressure switch going bad.I would try that first.

My oil pressure gauge in my 2008 dodge ram with 5.7 hemi just drops to no pressure than comes back up and drops right away again. oil is full


This could just be an Oil Pressure sensor has become faulty, Simply replacing the oil pressure sensor and it will solve the problem.

Oil gauge drops all the way down and check gauge light comes on


Could be the oil pressure sender has gone bad or worse case scenario the oil pump has worn out. Check the oil presssure sender first, if it is leaking around it then that is the cause, if not then you may be looking at an oil pump. Just had a 03 ram 2500 doing the same thing and it was the sender, but that was a hemi and it had 230000 miles and a month later had to replace the oil pump for same issue.

I have a 2005 Dodge Ram hemi 1500 4x4. would not start.


I suspect the gas tank has some crud on the bottom that gets sucked in when level is very low and/or truck is parked on an incline.Suggest installing in-line fuel filter, let gas level get nearly empty and then check in-line filter. If there's junk in the filter, tank needs to be cleaned. Or just keep the tank a quarter full until it can be cleaned.

Oil pressure fluctuating


The sensor could be failing to read the lower pressure when the engine RPM slows down. Or the pump could be failing. I would replace the sensor and see if that doesn't correct the problem
