Issues with a code P0339
 

Hello everyone,
I really need advice or pointers on what to do next, I have an Acura TSX 2009 and its been giving me issues for the past couple of months and i don't know what it could be. In most mornings or every morning when i go to start my car it takes a while to start and when it finally does start all the service lights you can think of come on my dashboard, looks like a Christmas tree. My steering wheel doesn't move and the break pedal and stiff as well so in order to operate my car i have to turn off the car and then turn it on again but there is times where i have to do this procedure 1-3 times every morning. The code indicates that its a crankshaft sensor "A circuit". i swapped out two of those sensors each located in different areas of the motor, one underneath and the other within the motor and the problem persist. Help Please!!!

Should have started a new thread but it sounds like you either have an aftermarket starter or a factory starter that's worn. What happens is the starter isn't turning the crank over at the correct speed and it will think the timing is off thus throwing a crank code.
When your car is just turning over does it sound like the starter is "skipping" or turning over at different rates? Does it turn slow then speed up?
And when a crank sensor code throws it may put the car into "limp mode" which is why it acts different while driving.
Not saying this is your problem but it is a common issue with these K24 motors.
Usually listening to the starter will confirm your diagnosis, it'll just sound "off".
Also check for any other codes it may be throwing.

OR you could have a software issue. I know this pertains to Accords but it's the same engine in the vehicle but I'm not 100% sure it affects Acura's vehicles but it's worth checking out.

The only issue I have had with my 2009 is some light oil consumption. Not a fun issue, but I just check it regularly and it doesn't give me any fits.
