Hello All,

I was bored one day so I decided to paint the header heat shield red. I had to disconnect the sensor that attaches to the header(2000 4Cyl Vetec) i neglected to re attach the sensor after I re attached the heat shield(LOOKS GOOD IN RED) I turned the car on and the check engine light came on. I turned the car off and reconnected the sensor...the light still won't turn off. Its been this way for days and days. If anyone can help please post! Thanks.

 

disconnect the battery for 20 min or so

 

I am glad there is a check engine light, so you can pull the codes and figure out what was wrong, but it is an annoying light to see, saw it only once on my old car.

 

you can disconnect the battery, or pull the ecu fuses (2 of them, main & backup) and wait a few minutes.

if you don't want to wait, disconnect the positive lead from the battery and touch it (the + lead) to the ground post, so the (+) and (-) leads are together. DO NOT TIE THE POSTS TOGETHER. that is what you do when you want to have july 4th early in your garage/driveway.

that trick also will reset the radio when codelocked...as in, you put the wrong code in three times and now it is making you wait a couple hours to try again. it lets you enter the code again right away. however, it does NOT bypass code entry.

note: doing this will erase your radio stations, clock, and most everything else that is user set as well. pulling just the ecu fuses will reset the ecu only, leaving your presets safely saved.

 

You get any paint in the harness? make a wire loop and see what code you are throughing and check it out, you may not be throwing the code to the header...

 

I didn't get any paint on the harness, I removed the heat shield completely, like I saidf...I was bored. Oh and thanks jfiedler for the suggestion!
