Discuss the causes and fixes for P1349 Toyota OBDII Code

  • The Code P1349 on my 2002 Toyota Camry AutoZone did the diagnostic on it and gave me a printout and it's saying that I have to replace the camshaft timing gear but the car has none of the symptoms of the camshaft timing gear going out but I read on this site that it could be that it needs an oil change or the timing's off can somebody help please.

  • If you haven't change the engine oil lately or if the engine oil is low and dirty, you should start by changing the engine oil and filter, and clearing the code.

  • 2001 Toyota Sienna is surging (cuts out and suddenly looses power without moving the gas pedal) and idling rough. P1349, P0300, P0301, P0303, and P0305 Codes with check engine light. New spark plugs, new VVT Valve, and new coils on cylinders 1,3, and 5 didn't fix problem. Also cleaned VVT Valve filters. Oil is full synthetic relatively new. Continuing to troubleshoot.

  • Thanks a lot, this has solved my problem.

  • will the check engine light go off on its own after the oil change and driving it around or does a shop need to clear it?

  • If the was the oil change, then the light will eventually turn off by it self in a couple of weeks, otherwise the oil change was not problem.
