Hello, is a P0335 code, crankshaft position sensor, ever related to the oxygen sensor(s)?

Question

I have already replaced the Crankshaft Position sensor, twice actually.
(Perhaps AutoZone resells broken ones?) But the code returns after the cycle.
Someone had the bright idea that changing the O2 sensors could help. I personally don't think so. Thanks again

P0335 Crankshaft position sensor circuit

When you crank the engine does the fuel pump come on.? This is a good indication the crank sensor is working, without the crank signal the fuel pump will not come one.The 02 sensor will not cause P0335, but a MAF (mass air flow) or even lrunning out of fuel.The best crank position sensor is OEM. Also whenever you replace the crank sensor a CKP relearn needs to be performed

Hello Reynaldo,  Thank you for your reply.  I hadn't known about the 'relearn.'  This could be my problem.  But I am happy that I can return these expensive O2 sensors.  cheers!
