reading CEL light blink

[steamboatnsx]

So I connected the jumper and the cel light blinks twice then a pause and blinks once. The light is lit for the same amount of time for each so I am thinking I have code 2 and 1 or is it code 21?


Thanks

If the blinks are all the same length in duration you have 2 separate codes as you suspect. Both code 1 and 2 are for the O2 sensors (front-bank2 sensor1 and rear-bank1 sensor1 respectively). Code 21 is for the front vtec solenoid valve (if this was malfunctioning I would think you'd feel it when vtec kicks in).
Good Luck!

Sounds like you do have a 2 and a 1, but you tube is great for this sort of thing.

In this example on another Honda, the guy has a code 12 only and it repeats. I think that should set you in the right direction

Great video. I haven't had to pull codes yet and I was wondering what the flashes looked like - THX.

Here's how you read the codes

Thanks for the clarification. I just wanted to make sure before I ordered both 02 sensors.
