2010 hyundai cam codes p0340 & 365 & no spark


Recommended Posts

got a true nightmare. Replaced 2 broken timing chain guides in a 2010 Hyundai sonata with a 2.4. Now it wont start and im getting error codes p0340 & 365 and have no spark. My last tech walked off with my lab scope so finding waveforms is not happening. Car ran fine when arrived(other than noisy). Anyone ever come across this

Sounds to me that the timing chain is not installed properly,, I am not sure since I have never done a hyundai , but it is possible that the vvti actuators (cam gears) need to be set before putting the chain on .. If the instructions are not followed exactly you will have problems.. one tooth can be a very large timing difference.. I have done several cars where you had to set the vvti actuators before installing the chain.. just because the marks line up doesn't mean you are set correctly remember the vvti allows for timing changes so the cam may be in a different position than what you think it is if you are just using the marks on the cam pulleys (vvti) actuators. You can check for signal using a logic probe or equivalent testing light . you don't have to have a scope in fact i hardly ever use a scope any more..

carbttech72, Did you find out what the problem was?? I find that most people don't seem to give any follow up on what they find. This site can be used as a good tool to help others that come across the same situation. any updates?? Just my 2 cents.

Imcca, yes I agree i like to help others , but I think in the long run knowing the findings can benefit a lot of others. Not to mention it is nice to to get even a little thanks for your input not just taking peoples help for granted, especially if they are nice enough to offer there help a lot of people out there just take the attitude it is not my problem so don't even give any input, so when some is given a little appreciation should be given in return, don't just keep crying wolf or you will find that when you really need help there will be no one to help.
