I was swapping heat shields for my car, so i unplug the sensor and replug it after putting on the new heat shield. Now when i go start my car it has a CEL. Did me unplugging and replugging the sensor do something?

 

reset the ecu

 

No, not unless your car was on when you unplugged it.
Perhaps you cut a wire when you removed the shielding.
Check the cel before you just reset it...

I double checked everything and I'm 100% positive i didn't cut anything. I'll be checking it today i suppose.

 

yeah just run the code, and then check everything make sure everything is still in working order, also maybe clean the plug and make sure the plug is inserted all the way...

then if all is well, reset the ECU

 

So i pulled the code and its 2 long blinks and one short blink, but im not exactly sure which code that is, anyone help me on this?

 

It will just keep repeating two long blinks one short blink, two long blinks one short blink.

 

21 is the vtec spool valve or as some call the vtec solenoid. In the rear left of the head. I guess you can start by checking that out then

Is something wrong with it or what? Do i need to replace it?

 

VTEC spool valve? Did you really just call it that?

It may need to be replaced, check the connection if it s good then probably replace it.

yes i did, and if you go to a honda dealership thats what they will call it. Its honda's actual term for it, we (other people) just like to call it a solenoid because thats basically what it is, and its easy than "spool valve" (which its listed as in my service manual).

 

Well I'll be damned.
