What are the Possible Causes of the DTC P0024 Nissan?

NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
  • Faulty exhaust valve timing control solenoid valve
  • Exhaust valve timing control solenoid valve harness is open or shorted
  • Exhaust valve timing control solenoid valve circuit poor electrical connection
  • Faulty Crankshaft Position Sensor (POS)
  • Faulty Camshaft Position Sensor

Code Tech Notes

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.

There is a Factory Service Bulletin for the following Nissan Models:
2009 Nissan Maxima
2010 Nissan Maxima
2011 Nissan Maxima

What is the Cost to Diagnose the Code?

Labor: 1.0

The cost to diagnose the P0024 Nissan code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.

When is the Code Detected?

When there is a gap between angle of target and phase-control angle degree, the valve will stop working and the ECM will trigger the P0024 code.

What are Code Possible Symptoms?

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Lack/Loss of power
  • Engine rough idle

What Does the P0024 Nissan Code Mean?

This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the exhaust valve.
The Engine Control Module (ECM) receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature. Then, the ECM sends ON/OFF pulse duty signals to the exhaust valve timing control solenoid valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to increase engine torque in low/mid speed range and output in high-speed range.
The intake valve timing control solenoid valve changes the oil amount and direction of flow through intake valve timing control unit or stops oil flow. The longer pulse width advances valve angle. The shorter pulse width retards valve angle. When ON and OFF pulse widths become equal, the solenoid valve stops oil pressure flow to fix the intake valve angle at the control position.
