Frequently Asked Questions

What does P0524 mean on a Duramax?

P0524 means Engine Oil Pressure Too Low. The engine computer has measured oil pressure below the minimum it expects for the engine speed.

Is P0524 a Duramax-specific code?

No. P0524 is a generic OBD-II code defined by SAE J2012, so it means the same thing on any vehicle that sets it. The exact conditions GM uses to set it on its diesels are in GM service information.

Mechanics Guide Step-by-step diagnosis

How Do You Diagnose DURAMAX-P0524?

  1. Stop the engine and check the oil level right away.

  2. Confirm the actual oil pressure with a mechanical gauge before trusting the sensor.

  3. Check the sensor and its wiring only after real low pressure is ruled out.
