i was running my b18c-r bringing it to redline enjoyin every second, until i slowed down at a stop light and got a engine light in my face......scared i went home and after letting it all cool down i started it back up and no light.....any idea what is up.....everything sounds and runs fine just wanna play it safe.....02 sensor? vtec solenoid? im running a stock jdm b18c-r with a p28 mugen ECU....thanx

ilovemyeg

if you where slowing down in a gear and the light came on its probaly o2 sensor.but you might wanna check the code anyways

HUBB

ok thats what i thought

slowEGhatch

same thing happens to me...

HUBB

what did u do....

i believe im having the same problem but as soon as i turn my car off to check the code it goes away, i cant keep it on, any suggestions? I was thinking of stalling the car out when its on and then check it? i duno

Grimm

you guys sure it dosen't save the code...

My Civic does something similar. If I'm really pushing and passing all over the place, mainly when I'm over a buck. I'll slow down and the engine light will come on. I'm sure it's a sensor getting hot. and combination loose wire in the harness that clicks into the ecu.

dantastic

same thing happens to me sometimes when i slow down the car with engine compression, or when im on the throttle really heavy for 15+ more sec. i checked it, and its an 02 code. it dissappears when i start up the car again (doesnt save the code). my guess is that im running too rich b/c of my 255lph pump.

B_CRUZ!

you guys are wrong. it does save the code. it temporarily goes away when you turn off the motor and start it again. Even though the check engine light is off, jump the ecu wire and it will tell you why the CEL came on. You reset it by removing the ecu fuse for 15 seconds or disconnecting the negative on the battery for 15 seconds. check the code though HUBB.

yeah im goin to jump the wire and read the codes.......its like all u were sayin on the gas runnin hardand then when i slow down i get a light......turn off and start back up and its gone......ill check it all out....thanx fellas.

xerox445

same for me, ill check it tomorrow or something, ill let u know

HUBB

so yeah we jumped the wires and it thru a 02 sensor code and that was all...... we cancelled the code cus of my chipped p28 and now its all good......there was nothin wrong with the 02 sensor it was just that the motor was gettin to much fuel so the computer just thru the code.....i think

HUBB

i havent seen it since and i was drivin hard and slow all night tonite????
