What does the p0521 code on the oil pressure sensor mean?
The oil pressure sensor calculates the oil pressure of the vehicle’s engine. 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.
What’s the code on my GMC Silverado Sierra?
It keeps popping up cel and code p0521. The sensor has been replaced, the screen has been replaced, the relief valve was replaced by dealer. It only has 7000 miles on it. Oil pressure runs around 35 warm running down the road and 15 at idle. The cel has always gone off while running down the road with pressure steady.
Is there a p0521 code for a Silverado?
This is my first post to the site and yes I have searched google many times for an answer to this but my problem seems to be somewhat unique also sorry for my punctuation, i tend to just type and rant sometimes
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 does the Diagnostic Code p0521 GMC mean?
P0521 GMC Meaning The Powertrain Control Module (PCM) continuously monitors the engine oil pressure. The Oil Pressure Sensor/Switch sends a signal to the PCM when the engine is running. The Diagnostic Trouble Code (DTC) P0521 is detected when the signal sent from the oil pressure sensor to PCM goes out of range.

When does the ECM set the p0521 code?
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.
