P0024 Code

The P0024 code is part of the On-Board Diagnostics II (OBD-II) system, a standardized system in vehicles since the 1990s. It serves to monitor various components and systems within the vehicle, alerting drivers and technicians to potential malfunctions.

Specifically, P0024 pertains to the camshaft position, indicating that the timing of the camshaft on bank 2 (usually the side of the engine containing cylinder number 2) is over-advanced.


When the P0024 code is triggered, drivers may notice a variety of symptoms, ranging from subtle to severe. These symptoms can include:

  • Check Engine Light: The most obvious symptom is the illumination of the check engine light on the vehicle’s dashboard.
  • Decreased Engine Performance: The engine may experience reduced power, sluggish acceleration, or poor fuel efficiency due to improper timing.
  • Rough Idling or Stalling: Erratic idling or stalling may occur, particularly at low speeds or when the vehicle is stationary.
  • Engine Misfires: Misfires, where the engine fails to ignite fuel in one or more cylinders, may become more frequent.


Several factors can contribute to the triggering of the P0024 code. These include:

P0024 Code

A malfunctioning camshaft position sensor can provide incorrect data to the engine control module (ECM), leading to timing issues.

Variable Valve Timing (VVT) Solenoid Malfunction:

The VVT solenoid controls oil flow to the camshaft phaser, which adjusts camshaft timing. If the solenoid fails, timing may become over-advanced.

Oil Flow Issues:

Low oil levels, poor-quality oil, or clogged oil passages can impede the proper functioning of VVT systems, leading to timing problems.

Mechanical Timing Component Failure:

Damage or wear to timing chains, tensioners, or other mechanical components can affect camshaft timing.

ECM Software Issues:

In rare cases, glitches or bugs in the engine control module software can erroneously trigger the P0024 code.

P0024 Code

Diagnosing and resolving a P0024 code typically requires a systematic approach, often involving the following steps:

  • Code Reading: Using an OBD-II scanner, retrieve the stored trouble codes, including P0024, from the vehicle’s ECM.
  • Visual Inspection: Conduct a visual inspection of the engine bay, checking for obvious signs of damage or leaks, particularly around the camshaft position sensor and VVT solenoid.
  • Testing Camshaft Position Sensor: Test the camshaft position sensor using a multimeter to ensure it is functioning within specifications.
  • Inspecting VVT Solenoid: Test the VVT solenoid for proper operation, checking for continuity and responsiveness.
  • Checking Oil Levels and Quality: Verify that the engine has sufficient oil and that the oil is clean and of the correct viscosity.
  • Oil System Inspection: Inspect the oil passages and system for blockages or restrictions, ensuring proper oil flow to VVT components.
  • Mechanical Inspection: If necessary, perform a mechanical inspection of timing components, looking for wear, damage, or misalignment.
  • Software Update: If all other potential causes are ruled out, consider updating the ECM software to the latest version provided by the manufacturer.
