my engine light doesnt stay on but after WOT through first and second... i think in 3rd the light comes on but cuts off when you turn the key off then on again

code 21 vtec solenoid and code 7 tps

but doesnt tps code flash if vtec is wrong? its a perfectly functioning and tested tps

my questions...
does the vtec wire have to be a certain thickness/gauge? and i dont have the other factory connector so i just have them connected with male/female connectors

I am having difficulty understanding what your asking. What do you mean "My engine light does not stay on?" What is "WOT" Please desbrice better what your saying when your driving in 1st gear ( what happens ) 2nd gear and so on.

The Vtec wire should be a stock factory wire thickness, but I have seen some people try to use some crap speaker wire which is not good. You can find the same kind of wire you need at a hardware store. But connectors are the easy way to go, but the clips are the best way to go to ensure connection.

 

its not on when i start it... only when i floor it through the gears

wot= wide open throttle

first and second are like normal

pretty sure i just hacked some wire off from a harness i had before but not completely sure

 

try adjusting your TPS, then see if that helps, are you using a stock ecu?

 

p28 w/hondata

ive adjusted it already. it never happened in my ef hatch. and the only things different were the listed things and i did replace the tps but it was tested already and works. any explanation for why you think itd be the tps on its own?

anything else to test out?

 

anyone?

 

anyone?

 

If the tps comes on after a wot run thats because the ecu saw voltage thats out of parameters. When you say you tested it, did you test it with a dvom ?

To check the vtec solenoid you also need a dvom. To check for resistance of the solenoid.


For your info you should see 5 volt reference from ecu. Check that there is a ground. Then slowly open and close the throttle body and look at the signal voltage going back to the ecu.
