OK I GOT A 2001 HONDA ACCORD LX F23A4 ULEF VTEC WITH A CHECH ENGINE LIGHT CODE P1381 WHICH READS CYP (CYLINDER POSITION SENSOR) INTERMITTENT INTERRUPTION,

I REPLACED THE WHOLE DISTRIBUTOR THEN RESET THE CHECK ENGINE LIGHT AND THEN AFTER 10 MILES OF DRIVING IT THE LIGHT CAME BACK ON AND ALL THE PROBLEMS START REOCCURING WITH THE CAR AGAIN,

ALL MY MECHANICS SAY IT MAY NOT BE THE SENSOR IT MAYBE AN ELECTRICAL WIRING OR A LOOSE WHERE BUT WHERE DO I START IF ANYONE OUT THERE CAN HELP ME I'D APPRECIATE IT THANK YOU

 

You could start by going around under the hood amnd making sure that all the connectors, like snap connectors, are tight, especially in the ignition system.

 

I'm not even going to read that...

Don't use all caps (stated in the ToS).
Make complete sentences so it's easier to read.
Make a better thread title thats descriptive of your problem.

thanks for breaking that up, now retype without all caps.

 

YOU GUYS ARE RETARDS, ITS PERFECTLY FINE TO WRITE IN CAPS.

 

really? You might want to read the ToS.
Or better yet, since I dought you'll take the time to go read it, here is the part that applies right now.

The link below has some info from Service News bulletins and some diagnostic info;

thanks everyone for your support espicially hondadude im new im sorry didnt know not to post in caps that daignostic pic helps im gonna try it out tonight thx

 

Yes, I know, I'm digging up an old post from the past, but it just saved me some MAJOR time and headache! Just wanted to post and say thanks.

I was checking things out since we're not getting very good MPG in our 01 accord LX L4 a/t - it averages 23-24 mpg city and 25-26 hwy... while i get 22-23 city and 24-25 hwy in my 98 v6 camry 5spd... which is supercharged! not bragging, just using it as a comparison point.

anyway, i pulled the dist cap (only 2-3 months old) to inspect the coil. apparently i didn't pay attention to which side the "spark shield" was installed on the coil, and just put it back in any which way - which happened to be the wrong way. MIL came on 2 drive cycles later, code P1381, and the computer lowered the rev limiter from redline down to 3000. made it feel like the auto trans was slamming into gears at times, or not shifting at all, and having a big reduction in power. I'd never heard of a CYP sensor before (cylinder position?? the cylinders don't move!), but I had heard of a distributor pickup coil. apparently the same thing.

After reading here, I flipped the shield back over to the inside of the coil (yes, it does fit both ways), cleared the code, and all seems to be well! Thanks for your great posts, guys! I've read plenty of stuff on here before thanks to links from PatrickGSR94 - I've known him since before he got his teg. If it hadn't been for him telling me about this site and then me seeing how thorough you folks are, it probably would have taken me a lot longer looking on google and trying to filter out all the ricer junk to find an actual solution. Instead i came straight here and found the answer in just a few minutes. Thanks again folks!

 

thanks for the info.....got a 1998 Honda that's posting codes p1381, p1382 and intermittently shifts to neutral (all the time)....making it undrivable.
