What does p0521 mean on an oil pressure switch?
The P0521 code is one of the trouble codes that denotes a potential problem with the engine oil pressure switch or engine oil pressure. If your code reader or scanner registers it, read this comprehensive guide to learn about its meaning, probable causes, common symptoms, and more.
When do I set the p0521 code on my car?
This is then communicated to the ECM in the form of a voltage value. The P0521 code is set when the ECM detects the voltage value is either higher or lower than the specified acceptable range of oil pressure. This code can also be set when the engine detects constant fluctuation of the oil pressure value.
Can a PF2 oil filter cause change in oil pressure?
The presence of the valve does restrict a little flow by design, but not having one on cars that require them would do more harm than good. For the record, the PF2 AC Delco filter I used on my truck did have the anti-drainback valve…it just sucked at supplying oil to the engine. – Jus – Rebuilding your journal bearing turbochargers since 2004.
Why is my oil pressure sensor out of range?
It could be out of it’s normal range or could be fixed when it should fluctuate. For this P0521 trouble code, the cause may be mechanical or electrical, but is more than likely electrical related. This code is related to P0520, P0522, P0523, and P0524.

What’s the po521 code on a 2007 Yukon?
5 people found this helpful. I had the sensor and filter replaced on my 2007 Yukon and I still kept getting the PO521 code. The PCM is looking for a certain oil pressure range and if it doesn’t see it, it will set the code.
What is the diagnostic code for oil pressure sensor?
P0521 is a diagnostic trouble code (DTC) for “Engine Oil Pressure Sensor/Switch Range/Performance”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
