Nissan sentra 2004 what is the check engine light with code P0335pd( up and down arrows between p and d mean)?

Question

I get two check engine light error codes P0335 and P0335pd(with up and down arrows in beween the p and d) with engine not running. Does any one know what the last code is and how it differs from P0335 ? Thanks

Answer 1

they are the same thing, one probably means current and the other one is old, just replace the Crankshaft Position Sensor
