P0024 code definition

Camshaft Position B - Timing Over-Advanced or System Performance (Bank 2)

What the P0024 code means

P0024 is the OBD-II generic code indicating the Engine Control Module (ECM) has determined that the bank 2 exhaust camshaft is in a more advanced position than what the ECM expected. The over advanced position can be during the retarding or advancement phase of the camshaft timing.

What causes the P0024 code?

  • By using the camshaft and crankshaft sensors, the ECM detects the camshaft timing to be over advanced.

  • The Oil Control Valve (OCV) to the bank 2 camshaft is stuck closed or has clogged passages.

  • The oil is too thick, causing the passages to become clogged due to lack of oil flow to or from the camshaft phasers that control the timing.

  • The camshaft phaser is stuck in the advanced position due to damage or defects.

What are the symptoms of the P0024 code?

  • The Check Engine Light is turned on and the engine is put in failsafe mode.
  • The engine may have a hard start condition.
  • The engine may run rough, hesitate or stall depending how advanced the camshaft is.
  • The engine may have a preignition problem on acceleration.
  • The engine's emissions may exceed federal levels and fail an emissions test.

Note: These symptoms may change depending on the camshaft timing positions.

How does a mechanic diagnose the P0024 code?

  • Performs a visual inspection to determine any electrical connector, wiring or valve issues of the camshaft oil control valve for the bank 2 exhaust camshaft

  • Checks that the engine is full of clean engine oil with the correct viscosity

  • Scans and documents the codes received and views the freeze frame data to see when the code was set

  • Resets and clears the OBD-II fault codes, retests the vehicle to see if the P0024 code comes back

  • Performs a manufacturer's specific pinpoint test for the P0024 code

Note: Follow the manufacturer's recommended pinpoint test to narrow down the problem and help prevent replacing the wrong components.

Common mistakes when diagnosing the P0024 code

Follow these simple guidelines to prevent mistakes: * Do a visual inspection to see if all electrical connectors are connected.

  • Check the engine oil to see if it is full, clean and is of the correct viscosity for the engine.

  • Test and verify the failure code comes back before any further tests are done.

  • The manufacturer pinpoint test procedures should be followed step-by-step.

  • Do not replace any sensors or components unless tests indicate a problem.

How serious is the P0024 code?

  • The engine may run erratic, stall, hesitate, run rough or have a hard starting condition.

  • The engine may have excessive fuel consumption, carbon fouling of engine components and various drive complaints depending on the camshaft failed position.

  • The engine may fail emissions testing.

What repairs can fix the P0024 code?

  • Clearing and retesting to verify the fault codes and performing a road test

  • Changing the oil and filter to the proper oil viscosity per the engine's specifications

  • Repairing or replacing the wiring to the camshaft oil control valve for bank 2 exhaust camshaft

  • Replacing the camshaft OCV for bank 2 exhaust camshaft

Additional comments for consideration regarding the P0024 code

The code can be caused if the oil is sludged up and has restricted the oil passages through the camshaft to the camshaft phasers, causing the timing to be over advanced.
