P0024 Nissan Code - Exhaust Valve Timing Control Performance Bank 2

Quick Answer

The P0024 diagnostic trouble code (DTC) for Nissan vehicles refers to an issue with the Exhaust Valve Timing Control (EVTC) system on Bank 2. Common causes include Faulty Exhaust Valve Timing Control Solenoid: The EVTC solenoid controls the flow of oil to the EVTC system, A malfunctioning solenoid can trigger the P0024 code, Oil Flow Issues: Restricted oil flow to the EVTC system due to sludge buildup or blockages can cause the system to malfunction. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0024 Nissan Description

The P0024 diagnostic trouble code (DTC) for Nissan vehicles refers to an issue with the Exhaust Valve Timing Control (EVTC) system on Bank 2. This system is responsible for adjusting the timing of the exhaust valves to optimize engine performance and emissions. When this code is triggered, it indicates that there is a performance problem with the EVTC system on the second bank of cylinders in the engine.

Common Causes of P0024 Nissan

  1. Faulty Exhaust Valve Timing Control Solenoid: The EVTC solenoid controls the flow of oil to the EVTC system. A malfunctioning solenoid can trigger the P0024 code.
  2. Oil Flow Issues: Restricted oil flow to the EVTC system due to sludge buildup or blockages can cause the system to malfunction.
  3. Wiring or Connector Problems: Damage to the wiring or connectors associated with the EVTC system can prevent proper communication and operation.
  4. Timing Chain or Belt Issues: Problems with the timing chain or belt can affect the synchronization of the camshaft and crankshaft, leading to EVTC system performance issues.

Symptoms of P0024 Nissan

  1. Check Engine Light: The most common symptom associated with the P0024 code is the illumination of the Check Engine Light on the vehicle's dashboard.
  2. Rough Idle: A malfunctioning EVTC system can cause the engine to idle roughly or inconsistently.
  3. Decreased Fuel Efficiency: Issues with the EVTC system can lead to decreased fuel efficiency, resulting in more frequent trips to the gas station.
  4. Engine Misfires: The timing of the exhaust valves plays a crucial role in engine combustion. A malfunctioning EVTC system can cause engine misfires or hesitation during acceleration.

How to Fix P0024 Nissan

  1. Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a visual inspection of the EVTC system components.
  2. Replace the Exhaust Valve Timing Control Solenoid: If the solenoid is faulty, replace it with a new one to restore proper operation.
  3. Check Oil Flow: Inspect the oil passages for blockages or sludge buildup and clean as necessary to ensure proper oil flow to the EVTC system.
  4. Repair Wiring or Connectors: If damaged wiring or connectors are found, repair or replace them to restore proper communication.
  5. Verify Repair: Clear the DTC and test drive the vehicle to ensure that the issue has been resolved.

Cost to Fix P0024 Nissan

The cost of repairing the P0024 code on a Nissan vehicle can vary depending on the specific model and year of the vehicle, as well as the extent of the issue. In general, the cost of replacing the Exhaust Valve Timing Control Solenoid and addressing any related issues such as oil flow problems or wiring repairs can range from $200 to $500. This estimate includes parts and labor.

Tech Notes for P0024 Nissan

Since the exhaust valve timing control solenoid valve uses oil flow to control timing, dirty oil can cause the valve to stuck open or close. Before replacing the valve, change engine oil and filter and reset engine code.
