P0024 Infiniti Code - Exhaust Valve Timing Control Performance Bank 2
Quick Answer
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the exhaust valve. Common causes include 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. 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 Infiniti Description
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.
What are the Possible Causes of the DTC P0024 Infiniti?
- 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

Discuss the causes and fixes for P0024 Infiniti OBDII Code
-
2010 EX-35 90,000 miles runs like a top at all speeds and conditions. No rough idle.. Service engine light soon has been on for 6000 miles. Dealer says it needs new CTS now VTC based on computer. Thoughts?
-
What oil weight are you using? when was the last time you change the oil? have you tired to clear the code?
-
There are two errors displayed on FX 35/2011
Both concern exhaust valves
P0024, P0014 Do you know the possible cause?
Is it possible that both valves (Sensors) are damaged at the same time?
Regards, Wojtek -
Yes it is possible. If the wrong engine oil weight is used or the engine oil and filter is to change as recommended by the factory, both exhaust valve timing control solenoid valve may fail at the same time.
Have you change the engine oil lately? what oil weight are you using?
