P0024 Fault Code

P0024 OBD-II Trouble Code Short Description

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

What does trouble code P0024 mean?

The P0024 fault code on cars refers to a problem with the B Camshaft Position in Bank 2. This code indicates that the camshaft timing in Bank 2 (usually the right bank of cylinders in V6 or V8 engines) is over-advanced or that the system performance is not meeting the expected parameters.

The camshaft position is critical for proper engine operation as it controls the timing of the intake and exhaust valves. If the camshaft position in Bank 2 is over-advanced, it means that the engine's timing is not in sync with the manufacturer's specifications.

There are a few possible causes for this fault code, including:

  1. Faulty camshaft position sensor: The sensor may be providing inaccurate readings, leading to improper camshaft timing.

  2. Timing chain or belt issues: A stretched or improperly adjusted timing chain/belt can result in over-advanced camshaft timing.

  3. Engine oil problems: Insufficient or degraded engine oil can affect the camshaft timing, leading to the fault code.

  4. Mechanical issues: Any mechanical problem in the camshaft or associated components, such as a worn timing gear or tensioner, can cause the timing to be over-advanced.

To diagnose and resolve the P0024 fault code, it is recommended to:

  1. Inspect and test the camshaft position sensor and related wiring for any fault. If necessary, replace the sensor.

  2. Check the timing chain/belt for any signs of wear or stretching. If needed, adjust or replace it.

  3. Ensure that the engine oil level and quality are adequate. If the oil is degraded, perform an oil change.

  4. Inspect the mechanical components related to the camshaft for any damages or wear. Replace or repair as needed.

It is essential to address this fault code promptly as improper camshaft timing can lead to reduced engine performance, increased emissions, and potential engine damage. If you are not familiar with automotive repairs, it is recommended to take your vehicle to a qualified mechanic or dealership for proper diagnosis and repair.


What are the symptoms of the P0024 code?

The P0024 fault code in cars is related to the B Camshaft Position - Timing Over-Advanced or System Performance (Bank 2). The symptoms associated with this error code can include:

  • Check Engine Light (CEL) is illuminated
  • Decreased engine performance
  • Engine misfires or runs rough
  • Engine stalls or idles roughly
  • Decreased fuel efficiency
  • Difficulty starting the engine

It is important to note that these symptoms can vary depending on the make and model of the vehicle.


What causes the P0024 code?

The P0024 fault code on cars is typically caused by the following issues:

  1. Faulty camshaft position sensor: A faulty sensor can provide incorrect readings, leading to timing over-advanced or system performance issues.

  2. Engine mechanical problems: Issues with the engine's valves, timing chain, or belt can cause the camshaft position to be over-advanced, triggering the fault code.

  3. Oil flow or pressure issues: Insufficient lubrication can affect the performance of the camshaft and cause timing problems.

  4. Incorrect engine control module (ECM) programming: If the ECM is not calibrated correctly, it may misinterpret the camshaft position and trigger the fault code.

  5. Electrical wiring or connector issues: Faulty wiring connections or damaged connectors can disrupt the signal from the camshaft position sensor and result in timing over-advanced or system performance problems.

It is important to diagnose and address the specific cause of the fault code to ensure proper functioning of the vehicle.

Possible Solutions

How to fix P0024?

To fix the P0024 fault code on cars, you can perform the following steps:

  1. Check the engine oil level and quality. Low oil levels or dirty oil can affect the camshaft timing and trigger this error code. Ensure that the oil is at the proper level and consider an oil change if necessary.

  2. Inspect the camshaft position sensor. A faulty or malfunctioning sensor can cause timing issues. Check for any corrosion, damage, or loose connections in the sensor wiring and replace if needed.

  3. Examine the timing chain or timing belt. A stretched or worn timing chain/belt can lead to incorrect camshaft timing. Inspect the chain/belt for any signs of damage, wear, or slack. Replace if necessary.

  4. Verify the operation of the variable valve timing (VVT) solenoid. The VVT solenoid controls the camshaft timing. Check for proper functioning of the solenoid and ensure that it is receiving power and ground. Replace if needed.

  5. Inspect the timing gears and sprockets. Damaged or worn gears/sprockets can cause timing issues. Check for any signs of wear, chipping, or teeth damage. Repair or replace as necessary.

  6. Perform an engine control module (ECM) update. In some cases, a software update to the ECM can resolve this fault code. Visit a dealership or qualified mechanic to have the ECM updated.

  7. Consider seeking professional help. If the above steps do not solve the issue, it is recommended to have a qualified mechanic diagnose and repair the problem. They have the necessary tools and expertise to accurately identify and fix the underlying cause of the fault code.

Remember to clear the fault code and perform a test drive after any repair to ensure that the issue has been successfully resolved.
