Symptoms

  • Check engine light on
  • Idle too high, too low or hunting
  • Stalling when coming to a stop
  • Speedometer or cruise control not working in some cases

Common causes

  1. Weak pump or restricted filter
  2. Leaking or stuck pressure regulator or control valve
  3. Leak in the pressure circuit or hoses
  4. Faulty pressure sensor giving a false reading
  5. Mechanical restriction or blockage

How to diagnose

  1. Compare the commanded and actual Engine Oil Pressure Too in live data at idle and under load
  2. Measure the pressure with a mechanical gauge to validate the sensor
  3. Inspect filters, hoses and the regulator or control valve
  4. Check pump supply voltage and current draw
  5. Replace the faulty component and recheck under load

Frequently asked questions

Can I keep driving with P0524?

Usually yes for a short time, but expect reduced performance or higher fuel use. Have it diagnosed within a few days.

Will clearing P0524 fix it?

No. Clearing only erases the stored code; it returns as soon as the monitor runs again unless the cause is repaired.
