How to reset the CEL (Check Engine Light)?
This one is for the FAQ, I hope
How does one properly reset the CEL? In this case, a 91 CRX HF. I searched HT, and other sites as well. =( It takes more than the ECU Fuse (15am under the hood)... Hazard fuse? =\ *edit* Hazard Fuse for 10 Seconds as per the Honda Service Manual! */edit* (This does not include pulling the battery. I would, but I have the stock radio, and do not feel like pulling it right now, losing radio presets, and I have to fix the climate control and cannot get into that now, etc) |
Re: How to reset the CEL (Check Engine Light)?
two options.
Pull the negative battery terminal off for a couple minutes Pull one of the fuses in the underhood fuse box for a couple minutes. Only problem is I can't remember which one :P It's a 10 amp in my 90 Hatch |

just remove the hazard/ECU fuse from the underhood fuse box for 10 seconds - top fuse in back row closest to firewall

Ah. I pulled the ECU fuse (15amp) but it still remembered the code. The Hazard fuse I think serves as the memory for the ECU.
I'd just like this to be documented! I will try that, but the ECU fuse alone doesn't cut it. |

The darndest thing is that now my CEL blinky LED (located in passenger foot well) is blinking without the paper clip, for the two codes mentioned (1 and 12, and 1 went away with the new o2 sensor from 2 months ago, and 12 went away with seafoam...). I need to replace fuel filter (this weekend!). See the other thread, this thread was just about resetting the code! Hazard here I come! |
