Update: Unplugged battery to reset code, which worked, and check engine light has NOT come back on...yet.

this is good. but if it comes up again, it's probably time to get dirty.

if the code came up before it will come up again...especially for a crank position sensor and your spark plugs are loose that either means 1 of 3 things....someone loosened them up and didnt tighten back down.....the compression is becoming too high cuz the timing is slightly off....or its time to replace worn plugs....

Any chance that it coming on in the first place was just a fluke somewhere?? //content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif

Yeah, if it does come on again I'll know what I gotta do. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

nope codes in honda's are never a fluke...unless someone just forgets to plug up a wire....which happens when in a rush...

The plugs have about 50k on them, the timing hasn't been messed with (doing the timing belt soon), and nobody has touched them but me.

Do any of the above relate to the crank position sensor, in terms of why the check engine light came on??

no.

and i've never heard of timing backing out plugs either. i wouldn't think compression could do that. but anything is possible i guess.

and 50k on plugs? which plugs you have?

the crank position sensor is to help the engine time itself....(within reason i mean its not gonna completely time itself for you) how long has the timing belt been on there....it could have slipped a tooth(or more) and caused a timing retard or advance...

i have a 12:1 compression in my crx....and have a habit of checking spark plugs every week...but then again i built the motor myself and i'd like to keep it in top notch shape....

If it slipped a tooth I'd be having all sorts of problems, I can't imagine that happened.

sorry to get off topic but we kinda have the same problem for my dads 96 intrepid....he had the check engine light for about 2 years straight(since then the light its still on)..we bought new sensors...problem didnt get fixed...bought new tranmission computer...it worked but for 1 year then the same problem came back..and we took it to the dealer..they couldnt find the problem..took it to autozone to get the codes...it appeared it needed new sensors(even though we already replaced them like 2 times)..sucks!!...the car runs great but only when the car gets warmed after driving it for more than 20 mins thats when it starts to run bad...it breaks it self hard everytime you stop at a stop light..it stays in 1st or 2nd gear...we dont know what the problem might be anymore...

no it can be retarded or advanced a few degrees before anything major happens....mine is retarded 2 degrees...until i get ecu tuned...NEED MORE FUEL TO BE DUMPED.

I highlighted the problem in your post.

how old is the car? 50k on a set of plugs seems like a LOT imo. but i just looked them up and those can last up to 60k depending.

but thats off topic...
