Check engine light is throwing one long blink. Is this 1 or 10? I am sure this will be easy to answer. Thanks in advance.

 

Is it repeating it?

Or is it 1 long blink followed by a bunch of short ones?

Long blinks are 10's and shorts are 1's

I.E. _ _ _ _ ..... Is 45

 

It is just one long blink. A couple seconds go by and then it blinks once again. etc.

 

That usually means the ECU

 

Damn, what does a code 1 look like then, and what does code 10 look like? Thanks for helping. It has thrown other codes, but I got those fixed. Are there any other symptoms of a bad ECU.

 

actually if he is describing this right, its code 10, wich is the intake air temp sensor.

 

Where exactly is this sensor located? I have a second gen JDM B16a.

 

its on the third runner from the left. its a little oval sensor with the 2 prong plug on the top. its 2 screws on it and has a plastic rod in the intake about .75" long.

 

That stupid code caused me a lot of grief on the dyno once. One long blink...I thought it was a code 1 (Oxygen sensor), but it was actually the IAT sensor. I was working under the hood between runs and I knocked the connector loose.

Sorry...no helpful info...just thought I'd rant. Honda really should not have used a code 10!

yes if its constantly on then that would be ecu but if it blinks long and does it over its the iat. its on top of the intake manifold.

 

Thanks, I will check that out in a couple of days.

 

Hey could the intake air temp sensor affect my thermostat, or is it totally unrelated. Here is my thread about the thermo prob https://honda-tech.com/zerothread?id=355213 Thanks

 

sounds like thermostat isnt opening up. change that and bleed the coolant properly and see if it makes difference

 

one long beep is a 10. If thats the only code it should repeat itself after a while. 1, would be a short blink.
