On vehicles equipped with V6 engines, the Check Engine Light may illuminate and code P0339 is stored for intermittent loss of the crankshaft position sensor signal. Our technicians tell us that adding a shim to the crankshaft sensor will commonly correct this issue but in some cases the flex plate may require replacement.
