HI there

Both of these codes are for the same part. P0335 is for a problem with the crank shaft position sensor, the other code is for the engine speed sensor. The P0727 code is generated because the ecm isn't sending any signal from the crank sensor. Replacing the crank sensor will usually resolve both codes.
