Your oil pressure gauge works with the oil pressure sensor, which is screwed into the block, to transmit a reading. A faulty oil pressure sensor can cause the reading on the gauge to be erratic. You may have a bad oil pressure sensor. You should also inspect the wires going to the sender to make sure they are not loose, corroded, or shorted. If a new sending unit doesn't work, you can check the oil pressure with a manual pressure gauge. Testing for oil pressure involves fitting the oil pressure gauge with an adapter. Then you will need to determine if you have a gauge problem or an actual oil pressure problem.
Don't run the engine with the oil light on. No oil pressure means no oil circulation, and damage will result. Have a shop check the oil pressure with a gauge that plugs into the oil pressure sensor port. If no pressure, check if you need a new oil pump.
Well if the coolant escaped and there are no external leaks, something happened to the cooling system to let it into the engine oil. Either a head gasket, intake gasket, or some other engine failure. I would probably notify the shop that did the trans service just in case it was something they did.
If the engine is not making any noise then it is likely not a real oil pressure problem. Just to make sure have the pressure checked by a shop with a mechanical test gauge and if found to be inspect replace the sending unit and that should in most cases cure the problem. I assume this is a pressure indicator.
If your oil level is full, light is off and no abnormal engine noises, if should be ok to drive to the shop. If light does come on, stop the engine. I would also have the shop check your oil pressure with a manual gauge, to determine the exact oil pressure reading. This could save you from major engine failure due to low oil pressure. I hope this helps.
The oil light is triggered by only one thing - the oil pressure in the engine is too low. Without oil the metal parts of the engine rub themselves directly, causing the sound you heard. Running the engine without oil is a sure way to completely destroy it extremely quickly - under no circumstance you should run the engine in this condition.
Only one thing can cause the lack of oil pressure: a failed oil pump. The fix is simple: you drop the oil pan and you replace the oil pump. If a mechanic can't diagnose that then either is an idiot or is trying to scam you. Take your car to a real mechanic's shop and have it fixed. And from now on stay away from these dishonest shops which almost surely have milked you of your money long enough: fuel pump replaced 7 times?? the gauges??? fuel tank???? Really??!??
This could be a lot of things. The 'check engine' light is only an indication that somethign is wrong. this usually only means that a sensor that determines how the car will rn is broken, wore out, or lost connection. I would take it by a shop. what they will do is plug your car into a computer ( that costs thousands) and the computer will give them a code that will give hints to what happened and what needs attention. if the light is only on sometimes then it's just a connection but on all the tiem you need a new sensor somewhere. hope this helps
I had the same problem with My jeep, when i took it in to a shop, they couldn't find any problems, , after about 5 shops and a ton of headaches from the low oil pressure warning, they found out that the gauge had gone bad, you may want to look into it as well.
Your Dodge sounds as if it actually has several separate problems going on,first,with the check engine light,have it scanned for diagnostic trouble codes,and have the technician write down the code number and definition (description).This could lead down a diagnostic path that might explain some of the things going on with the truck.The oil gauge,take it back to the oil change place,and INSIST that you think they installed a defective oil filter.I had a defective oil filter cause my oil gauge to go whacky too.Hopefully the codes will lead to some clear problem,when you get the code numbers and definitions,come on back and we'll try and work through them with you.Another option is buying an OBD2 code reader.They can be bought for around $60,and you won't have to go a mechanic or AutoZone to get codes out of your vehicles.Good luck.Thanks for using Fixya.com
