well my check engine lights keep coming on for me. I have a aftermarket header and the 02 sensor i had to splice to make it long. Well i was driving then i sped up around 90 then i slowed down after that my light went on. I stopped looked under the hood around the Headers and the 02 sensor checking to see if it was that but no problem at all. Start up the car then the check engine light was off. I'm just wondering now when my engine heats up my check engine light pops on. I checked my coolant and everything and it is fine. Any question or opinions will help thanks.

 

Well, being you recently extended your 02, it may be a lose connection there. Seems logical if this has been happening since youve done that.

Get the CEL to come back, and check it yourself when it pops up and see what code it throws.

check what code your car is throwing for starters

 

only problem check engine light only pops on when it gets hot the engine then when i turn it off and turn it back on the check engine is off

 

alright got it...its a code 22 VTEC pressure valve so i went to look it up it says that the oil might be to low for vtec to kick in or the VTEC pressure valve / switch might be done so i need to get a new one im hoping it will be low oil but i doubt it will look into it tomarrow

Check your oil then. Did you unplug anything else recently? Unplug and replug? Mix up connectors?

 

alright this is what i did i went to check the oil it is fine....i don't know how to check the pressure valve so instead i put back on my factory ecu not chipped or anything and the check engine light is offf.................in conclusion im guessing my vtec might be kicking in to early with the chipped ecu but its weird it started to act up now so now im checking the chipped ecu and making sure everything is soldier correctly and making sure its on the ecu board thanks
