I have a 01 Accord. I got the front crank seal changed about 2 weeks ago. A few days after the seal was changed It wouldnt start it would start to turn make a metal on metal grind noise and die. After 7 trys the grind noise went away and it started but it still hesitates when starting. the engine wont rev above 2900 rpm. I get the CEL code P0335, Crankshaft Position Censor Circuit Malfunction

When the front crank seal was replaced could it of messed up the censor or the crank its self?
