Frequently asked questions about P0520
What does P0520 mean?
Diagnostic Trouble Code (8 variants). The control module detected improper operation of the Engine Oil Pressure Sensor/Switch circuit.
Is P0520 generic or manufacturer-specific?
P0520 exists both as a generic OBD-II code (same meaning on every make) and with 1 manufacturer-specific interpretation(s): Ford. Always read it in the context of your vehicle.
Can TuningBot remove P0520 at file level?
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry. Checksum correction is not included: it is a separate, optional service. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
