Replaced the clutch about 6months ago, never did a crank relearn and now I'm getting a P0339 code, Faulty signal from the crankshaft sensor 'A'. It takes a bit for it to start and it's usually in limp mode when it finally does. My question is, should I replace the crankshaft position sensor or just relearn it, and if I do replace it, do I still have do relearn, since all it sends out is electrical impulse, based on my prior experience, it should relearn itself. Also, does anyone know how hard is it to get to the crankshaft position sensor, I kind of have an idea of where it is but haven't had the time to look for it yet? Thanks for taking the time to help.
