well i have a Ek 98 with a jdm b18c in it, i know this has nothing to do with a type r, but i noticed other fields are noobs. Well anyways i was on my way to work crusin in 5th gear all of a sudden CEL comes on. So i test it out and throw a oxygen sensor heater. So as i go to acura to cheak how much o2 sensor is, i start leaving and for a good 10 miles no CEL, can anyone help me out. Why all of a sudden it went away.

well how it works, is the whole fuel emissions system is constantly checking the duties of each part, being egr, o2, etc. anywho if it throws a code cause it messed up, it could be a temp code and not a hard code, if it's a hard code, that means it's broken and something needs to be fixed cause something keeps causing it to fail, but if it's a temp code, if it doesn't sense the failure after a certain amount of passing trips, meaning starting the car, driving it at a certain temp, mileage, etc, and it passes each time after it sensed the first failure, then the MIL(CEL) will turn off, it should store in the ecu when it happened and what conditions, well i work at honda bellevue, and usually when we get those codes, we replaced the o2 sensor, i know at bellevue honda there is a an extended fuel and emissions warranty, which is 8 year 80,000, but seeing as this is a swap, you're outta luck, sorry bout that, but just wait, if the light comes on again, then replace it, until then drive HARD, hahaha, peace.
