Engine is running fine. Oil level is good. Oil light comes on and off at random. Engine isn't knocking and runs great. Recently changed to GTX extended milage oil. Problem developed


The oil light comes on when the oil pressure sensor detects low oil pressure. The amount of oil has little to with it, although very low oil levels can cause loss of oil pressure. Since you aren't getting knocking, chances are the oil pressure sensor is defective. Replace it and monitor the situation closely. This could be a serious condition if allowed to escalated and it turns out to be an oil pressure issue.

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 !

Has no oil pressure i drove it over ten mile still runs good but no oil pressure


Just because it runs good is no reason to drive it into the ground. No oil pressure can ruin an engine fast. Hopefuly the reason no oil pressure is the sensor is bad, it's connection is corroded and thus bad. If mine I would take it to a shop and have them actually measure the oil pressure with a mechanical gauge. If no oil pressure that way, you know you have a serious problem. If the mechanical measurement is good, then you know that The sensor is bad, it's connection is bad, or the oil pressure light or ? gauge
is bed on the dash panel. Good luck.

Replaced oil sensor light still comes on


MAY---May-be you really have low oil pressure.. The way this sensor works is when you turn off the engine it closes to ground.. and when you start the engine.. the oil pressure opens it and the light goes out.. SO.. if the wire going to it is grounded out somewhere between the sensor and the dash board the light will stay on.. 3 choices.. 1. bad sensor (even though you replaced it) 2. wire is shorted to ground.. remove wire from sensor while engine is running.. light should go out. 3. you actually have really low oil presure. next.. after you have exuasted #1-2. you can remove sensor and install a real oil pressure guage and see what the pressure really is.. If you have very low or no oil pressure..1. Check oil level.(probably should have done this first) 2.pull oil pan and replace oil pump.. while you are there check a main bearing and a rod bearing for wear.. worn out bearings will cause low oil pressure. If you have good oil pressure install the pressure guage permanetly and forget about light.

Po521 code on a 2010 Camaro ss


Possible causes
- Low oil level or motor mechanical fault
- Faulty oil pressure sensor
- Oil Pressure Sensor harness is open or shorted
- Oil Pressure Sensor circuit poor electrical connection

When is the code detected?
The P0521 is detected when the signal sent from oil pressure sensor to PCM goes out of range.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Oil pressure warning light ON.
P0521 Chevrolet Description
The PCM continuously monitors the engine oil pressure. The Oil Pressure Sensor/Switch sends a signal to the PCM when the engine is running.

Rough idle


Low oil pressure is caused by bad bearings, low oil level. faulty oil filter, pump pressure regulator faulty and wrong grade of oil .AS to the other run the fault codes to check for faulty sensors.( probably MAF sensor )

Oil light came on runs really rough and then shuts down. so far i replaced fuel pump, mass air flow sensor, oil pressure sensor and oil level sensor. nothing yet. no check engine light either.


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.
