the check engin light came on on my 97 4.0 last night one code I looked up in my fsm was 21 seems prity strait forward I need to change my o2 sensor/s.
The other code was an 11 "no crank refrance sig during eingin cranking" also "intermitten loss of either camshaft or crankshaft position sensor"' and"ckp sensor target windows have too much variation" What should I do to fix this??
Thanks for your time, Ben
 
It could be you just need to clean the connector pins for the crankshaft position sensor. I would do that then clear the codes. And see if it comes up again. If it does, it might be that your CPS is going bad.

How many miles are on your 97?

I've got 120,000miles on my 99 and haven't had to change the oxygen sensor yet.
