this link says its a brown wire and a green with white striped wire....will i burn anything if i stick that paperclip into the brown wire and black wire???

Hey

Yes you are meant to connect the two pin wires together. I used a paper clip and it worked fine, turn the iginition off and on again. check for flashes.

Hope this helps.

info on testing is in the factory service manual. if its broken replace it!

FSM is Factory Honda Service Manual. not crappy haynes ones

can be downloaded from here ----> http://www.spoonertuner.com/manuals

not sure what could be wrong. Looking through the service manual the method of checking it is pretty complicated and unless you have the correct tools may be difficult.

ok...now i had a look at the ecu and its a P30 ecu...so i googled on p30's and apparently they are for b16a engines...

do you think that might be why my car feels more of a b16a and is causing the check light to turn on?
