Diagnostic codes

[Chester]

Hey, I am new here and I have noticed the CEL come on once or twice when I hit a big bump. Only had my van for a few months and it has 205 k miles on it. I have been reading through the threads and decided to check my codes.
I got 2 4 2 : any ideas? i got it twice but I need a thinner wire to just shove in there, I have to monkey around and then quickly look at the dash.
Thanks for input. I looked at the PDF for my van years and can't decide if it is telling me 24. 2 or 2 42.

Ok, I filed down the wire and this time I got 22 and 42. I'll look those up and let you know
