every time i downshift to slow down or coming to a stop light my CEL always lights on. if i shut the car, and start it again the CEL is not there anymore. i was trying to get the code but it seems like it just blinks really fast over and over again and it will just doing that up to whatever.....the CEL is not solid so maybe thats y i cant pull the code? and yes i did this over and over again https://honda-tech.com/zerothread/1901557

when it blinks really fast count how many times it blinks it could blink 9 times real fast stop for a second and blink again fast u just need 2 learn 2 read the codes

it will just blink really fast, it blinks every 4 secs. and over 9 blinks thats y i can get the code.
can u get the code even though your CEL is not solid? becuase like i said the CEL comes on whenever i slow down in any gears. and if i shut the car off CEL is gone.

if the cel pops up but u turn off the car and it goes away it doesnt matter u should still be able to read the code just jumper the plug turn the key 2 acc and count how many times it blinks

h22bb1

yea thats what i did. it will just blink forever.
i tried to pull the map sensor and i was able to get the code.
what if u get a solid CEL while the pin is connected?that means what?

doesn't sound like you are checking the codes appropriately. when you jump the socket the light will blink fast blinks equal 1 and long blinks represent 10s. you should have all of your sensors connected when you are checking with the car off and the key in the accesory position. if it resets when you turn the car off it is a resetable code so it sounds like your O2 sensor is reading too high of an a/f ratio. what kind of exhaust are you running? cat converter? has it always done this? did you do the swap, or did you buy it from someone already done? did they have any problems? these are questions you should go over and get some answers to.

well i tried my buddy's ecu ls integra p75 and it works fine...no cel or anything..so i guess its my ecu?
my o2 sensor is new btw. i got rsr exhaust with 12" resonator.
