P0024 INFINITI

P0024 INFINITI - Exhaust Valve Timing Control Performance Bank 2

Repair Importance Level: 3/3
Repair Difficulty Level: 3/3  What does this mean?

P0024 INFINITI Possible 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

First diagnose P0024 INFINITI code

    Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.

P0024 INFINITI 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.

Cost of diagnosing the P0024 INFINITI code

    Labor: 1.0

    The cost of diagnosing the P0024 INFINITI code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.

When is the P0024 INFINITI 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.

P0024 INFINITI Possible Symptoms

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

P0024 INFINITI Meaning

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.
