96 Chevy blazer how do I get out of safe mode ran low on oil now runs an drives but won't let car go fast past 2000rpms


The computing system on your vehicle has no safe mode for running low on oil . The only thing that will happen is the check gauges light will come on.
The oil pressure gauge is an analog device that is located in the IPC. The oil pressure gauge is operated directly by the oil pressure sensor circuit. As the engine oil pressure changes, the resistance of the sensor and the current flow in the oil pressure gauge changes. The current flow in the oil pressure gauge causes the needle to move in order to appropriately display the engine oil pressure. A sensor resistance of 1ohms will display as 0 kPa (0 PSI) and a resistance of 88 ohms will display as 80 kPa (80 PSI ). The IPC also monitors the oil pressure sensor circuit and interprets the current flow in this circuit in order to determine when the engine oil pressure is too low. If the oil pressure is too low, the check gauges tell tale will turn on. The oil pressure sender is located on the left side of the 2.2L. The 4.3L engine, oil pressure sender is located at the top left side, near the distributor/high voltage switch.
Try disconnecting the battery cables an hold them together for ten minutes , reset ECM !

Either you have way to much oil in the truck or the pressure switch is no good.

The check gauges light alerts you to the fact that one of the gauges is reading out of the normal zone. From what you have said I assume there is a problem with the oil pressure gauge in that it indicates the oil pressure is low. I suggest you remove the oil pressure sending unit and hook up a test gauge, see what the oil pressure really is. I suspect you just have a defective oil pressure sending unit.

Thank you for being very clear, most of the people on this site write very little or very poorly.

On that note, on to options. It's either (in my expert opinion) an internal engine problem, or your computer/spark plugs needs to be replaced.

Step 1: Get a tune up, (100 bucks) if already done, than I'm proud of you.
Step 2: Go to a mechanic and shell out 50-80 bucks to get a specialized computer hooked up to your car to tell you any and all of the problems with your car.
Step 3: get overcharged by said mechanic to fix it, or do it yourself and grow some chest hair.

Hope it helps.

The oil pressure guage on my 2000 Jeep Grand Cherokee is registering 0. My oil was just changed and I don't see any indication of oil leaking anywhere. Could it be the sensor?


First off I wouldnt drive your car until you make sure that you have indeed oil pressure and that the gauge is a false reading, driving your car if in fact it has no oil pressure will severly damage your engine, but firstly i would check the oil pressure switch its located on the passenger side of the engine right back from the oil filter make sure the connector is clean and free from oil and corrosion if the connector appears to be in good shape take a paper clip and insert it between the 2 terminals inside the connector your oil pressure gauge should peak at 80 PSI that tells you that your gauge and all related wiring are good and in working condition, secondly remove the oil pressure switch and hook an manual oil pressure gauge up to you engine and start the engine the guage should have a oil pressure reading anywhere from 30 PSI to 55PSI depending on engine temperature if theres oil pressure on your manual gauge replace the oil pressure switch with a new unit, if you still have 0 PSI on your gauge then stop your engine immediatly and start looking at your oil pump and lubricating system for a problem.

The oil sending unit is located on the engine block behind the drivers cylinder head area.You have to climb up on the motor to see it cause it is hard to see behind the wiring harness.You may also want to purchase a new sending unit because it is very long and you might need to buy the sending unit socket to replace it.Hope this helps.Good luck.

Oil pressure gauge shows 60-80


the oil sending unit that screws in the block beside the oil filter may be faulty,
the worst thing would be the oil pump its self the regulator valve on it

Oil pressure gauge reads past 80


now unless there is a very loud knocking of the motor which would mean that the engine's top end was not getting any oil I would say that your oil guage is sprung and needs replacing. a high pressure rating would indicate a restriction in the oil flow pasdt the sending unit or a plugged oil filter. if the filter were plugged you would know it because your enging would run tight in no time at all. replace the guage itself... please rate this........thanks
