I unplugged the VAFC at the connector for security reason while parking outside. After I reconnect the VAFC and start the car, the check engine light came on. What I did was turn off the car, reconnect the VAFC, and disconnect the battery for a second or so. When I turn the igntion, the check engine light is gone. Is this check engine light something I need to worry about? was is just a bad connection?...I'm just paranoid since this is my first check engine light. Thanks guys

 

i would only worry about it if it comes back.

 

check engine light alot of times dosent mean ****, well it does mean something but it can be pointless like mine was, my fieldsm vtec controller used to make mine come on and it was ****** with the map sensor which i didnt know so i had a diagnostic run for 40 bucks and found out it was my v-tec controller

 

my car did the same thing. i checked the codes and it was the map sensor and the vtec presssure switch. the light comes on b/c the car is reading the ecu settings and not the ones you put into the vafc. plug it back in and reset the ecu.

 

thanks guys,
how do you reset the ecu?

 

can anyone tell me which is the back-up fuse in the fuse box.

 

In the engine compartment, it is the 7.5A Blue fuse (I think).

 

undo the negative cable from the battery for a few minutes.. should be reset then..
