is 4.74V (measured) equal to approximately 5V ?

a lot of times i get 5.04V, which i assume is equivalent ... but is 4.74 too big of a stretch to satisfy this?

 

if you round up yes its five volts. But I not sure what kind of volt meter you are using. I seen cheap one be off a full volt. And trust me 1 volt makes a big diffrence

 

hmm, well its a nice meter ... i measure accurate volts on most things ... i am concerned on the reading of .25V off ... from my memory this is not an acceptable substitute for 5V.

I think the meter is accurate ... but as i said i am throwing a CEL 3 code so anything out of the ordinary (such as 4.74V) should be of concern to me. Thanks for your input however.

 

just bumping this to find out is 4.74V is acceptable if the service manual talks about "approx 5V"

You said that?

I don't see that anywhere? To <u>me</u> it looks like this is the first time you mentioned code 3.

EDIT:
BTW: No, that's definitely not acceptable, what's it for, anyway (what are you measuring that's coming out 4.74v)?

Sorry Syndacate. I forget that readers of certain threads may not read all threads, it makes perfect sense I myself only read certain threads that I am curious to know more ... or an area where I can help.

Yes, im throwing CEL Code 3 while the engine is running as per another thread. Here is the flow chart I got from the Honda Manual, and also what results I got so far ...




now, on the final step, I get 4.74V, when I should get 5V. This I think is a problem ... however I have 2 ECU's here, P13, and P28 ... and I get CEL on both ...

so both ECU's give the same ... so Ithink i am goign to have to do some more thinking on thsi one ...

 

up up and away

 

ahh, fixed it. it was a short in the white wire. No more CEL.

now, i just have to figure out where my battery drain is coming from ... ?

Glad it was something simple man...I love that feeling of relief when you finally figure out electrical problems. Good luck w/ the battery issue, I wish I could be of help.

 

for battery drain, you can leave the car off (key removed) and test for currant at the fuse box (under dash, and under hood) check each fuse with a meter.

if you find current, see what it belongs to( clock would have current with car off for example) and you can at leaste get a general idea of what is causing this.

another thing to look at is any electrical work you did recently, maybe a fog light install, or after market gauges. perhaps you wired something to be on all the time on mistake?
