The cel only comes on when at idle. It doesnt act up any other time. does this sound like a typical knock sensor problem and if so whats the best fix. thanks

 

any help at all

 

maybe no one knows the answer

 

If this helps it happens when idling at around 800rpm at 1000 though it is fine. any ideas.

 

Might want to look at the stickies at the top to find out what your CEL code is for, instead of guessing.

 

Ive checked it. I know it is the knock sensor that is why im asking if that is a common problem.

 

try changing the knock sensor and go from there

 

Is it possible it could be in the wiring? Im planning on chipping the ecu in the future anyhow.

 

yes, that is very possible. nothing is perfect and everything breaks sooner or later.

 

The wiring is one of those one off i had to wire it in myself jobs. could the resistance be off. or something odd.

 

in your situation, i'd expect that the resistance wouldn't affect the signal unless it is extremely high. I work with electronics on a daily basis. All it really takes is one wire to get cut by an abrasive part of your chassis.

 

there not cut i just recently ran them with new wire and they didnt work to begin with.

 

my cel code 23 only comes on when i rev past 3k or hold it around there for 10 secs. are you sure you are getting a cel for the ks?

 

did you use shielded wire?
did you solder or simply twist it?
and did you shrink wrap it?

i had the same issue because i didn't shrink wrap it, someone told me the wire had to be shielded or something, i figured it was worth the effort so i went ahead and shrinkwrapped it and its worked fine ever since.

 

hey instrument, you think this will work on a F22b engine ? i've had no luck so far. i did it with so many different types of wire already, except shielded. maybe i should really see if there is a voltage going through it. do you have a pic handy of your setup ?
