Can low oil cause P0521 code?
The P0521 engine code may point to a faulty oil pressure sensor, but it can also indicate insufficient oil pressure. In some cases, the low oil warning light may illuminate. If this situation is left unaddressed, it may lead to complete engine failure.
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.
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 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.
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.

Where is the trouble code on a GMC?
When retrieving GMC trouble codes with an OBD II scan tool, proceed as follows: 1. Connect scan tool to the 16-pin data link connector (DLC) located underneath the steering column. The connector may have a removable cover. 2. Turn the ignition on.
