P0340 error code and version error

schoe · Post by **schoe** » Thu May 21, 2009 11:15 am

I recently installed a machined VTC in the motor and when I plugged in the laptop to the ECU, this error code came up...

Would one of the reasons be the sensor wasnt properly installed correctly or did it really go bad?

Also when I tried to load a cal, I got this error...

Thanks in advance.

Please post calibrations and datalogs showing the problem.

To fix the second error re-upload your calibration to the ECU.

The first problem indicates no signal from the intake cam sensor. Check the plug, and then follow the troubleshooting guide in the manual.

Thank you for your response.

I guess the kal loaded once reloaded and I unplugged and replugged and it still gives me the error code but now the kmanagement actually gives me a reading back for the angles.

I have one more question... I did some datalogging and the VTC wont go past 26 degrees... I am currently running the TSX race header/exhaust kal. Do I have to enable something else in kmanagement to get the VTC to go to 45 degrees? I do have the VTC machined. Thanks again in advance.

if you are getting an error code you need to fix the problem that is causing the error code first.

It seems like its on and off with the error code. I would turn the car off all the way, plug it in and sometimes its there and some time its not... I did this about 7-8 times and about half of the times it would throw an error and the other half no...

I disconnected/reconnected the battery and now the error code is gone... :)
