Spool Assembly Replacement
 

Just changed out the spool assembly on a 2003 EX 4cyl with a brand new Honda spool assembly unit from the Honda dealer after getting a check engine light and a P2646 code. Also had an oil leak from the unit (cracked and flattened gasket) anyway, the oil leak has stopped but the check engine light is still on after starting. What’s up here?

....Forgot to reset. Fixed.
