Consider getting a service manual. I believe it can be checked with a multimeter. As with any sensor, either the resistance or voltage needs to be checked. If it's pegged at a minimum or maximum voltage or resitance reading while the engine is running, it's probably a good indication it's bad.
Otherwise a scan tool might be able to interface with the computer and tell you which of the 2 sensors is giving an out of range reading.
If you have no idea what I'm talking about...then you're relegated to being a "parts changer", and you can buy 1 new sensor, take a 50/50 shot to see if the problem is fixed. If not, swap sensors again.

sounds about normal for 90% at 700 miles. But remember that monitor is set up for 10,000 mile intervals. 10% = 700 miles X 10 intervals = 7,000 miles (100% used). See how close it really is?
And I love the urban myth that Honda uses "special break in" oil. No one has ever proven that is true at all. But I usually change the oil at around 1000 miles regardless of what the owner's manual says. I had a couple of honda's before that I listened to the oil change recommendations and didn't change the oil at 1000 miles, the fuel economy wasn't as good then as it was on the one I did the first oil change at 1000 miles.
But if you don't want to change the oil at 1000, then definitely at 3000 miles you should change it out. Then after that like you wanted around 3500-3750 miles.
and you're welcome for the help!

I agree taht it's a urban myth. Most point ot higher level of moly in oil samples taken. But that is most likely from the assembly grease used when the engine is assembled. it has an extremely high moly content to protect the components parts during the first start-up before oil makes it through all the passage ways and it fully bled. Also, it's nessesary to rotate some engine parts during assembly and for some of the engine tests performed before it's installed.
Theres simply no need for a special oil. In modern engines, there's not a whole lot of break-in that actually occurs after the first 2 or 3 miles... which are done at the factory.

Thanks motoguy. I have a pretty good idea what you mean. I am not a mechanic by trade (stay at home mom actually) but I can read and I am handy so I am not totally lost! I spoke with a friend of mine who has an OBD I can borrow, but I am thinking I will change both anyway, since the car has 114,000 miles on it. I will most likely recoup the money for the second one on what he makes up in gas mileage.

That's why I (and most people) put it in quotes. But it does have high moly content from the build and Honda must think it provides some benefits because everywhere you look, Honda recommends not changing it early.
Who knows engines better than Honda?

Isn't an "urban myth" a rumor that gets accepted by many as the truth? In this case, we have no rumor. Honda says they use a special break-in oil. It recommends leaving that oil in the car until the first scheduled oil change. That's not a rumor. It's a fact.
You're right, though, about one thing. I haven't actually proven that Honda is telling the truth. First, I trust them not to lie about something like this, and, second, I suspect if they did, one of the auto testing outfits would enjoy very much exposing such a lie. So far, none have.
But one thing is for sure, no one here is likely to change their mind about the appropriate frequency of oil changes. Good luck to all.

Just in case this might help, the trouble code reads like this:
"P1166 Primary H02S (No. 1) Heater System Electrical"
Wish I could offer more, but I'd be the blind leading the blind.

I think the main concern from the Honda engineers is that fresh oil won't allow as much engine wear. So it's desireable to leave it in for a longer period to finish doing it's job. I'm still not convinced it's a special formulation. If it is, it's only special is the what level of the typical additives or friction modifiers are included.
That being said, Honda loves to sell you THEIR fluids it seems more than most other companies. In the motorcycle world, it's not uncommon for other manufacturers and dealers to use Honda grease for routine services such as lubricating drive shaft splines or during engine re-assembly.

Sep 10, 2009 (9:16 am)
I am planning on buying a CR-V EX-L w/o Nav.
I spoke to a salesperson at Coral Springs Honda who wanted $6K down and 400.00 per month for lease and 7.8K down and 400.00 per month to buy.
I thought the guy must think I am an idiot so I left.
Anyone recently purchased a car like this one in this area and how much did you pay?
It is common on Hondas with digital HVAC controls to have the voltage regulating transistor to fail. The dealer charges about $70 for the module. The replacement is probably an hour of labor, or free if you do it your self. Some have just soldered a replecement transistor into the existing circuit board for $10.
So, yes, it does sound like the shop misdiagnosed the problem. Honda shop manual lists self test procedure for the HVAC controller (control head in your case). It is fairly simple and does not require special tools.

Hi. I am new to the forum and have a question about my husbands CRV. His car failed inspection for emissions. The code was P1166 which apparently is the O2 sensor. I am more than willing to replace it myself since Honda wants a ridiculous amount of money to do it. I know I will need an O2 socket, but my question is this: Is there any way to tell which O2 sensor is bad? There are 2 and I don't want to replace the wrong one. Any help would be appreciated as well as any advice on how to go about the actual replacement. This will be my first ever attempt at auto repair!
I am pretty sure 1166 is the primary O2 sensor. The shop manual should have it listed, or google it.
