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?
