Hi there fellas im new around here salutes to all of you I decided to register here because Im a huge fan of the Honda Fit and because I have a problem with my Fit. The CEL came on a few days ago and after verifying it with a computer I got the following code:

P2647

The car is consuming a lot of gas, does not throttle after 4000 RPM and Cruise Control is not working for some reason, it used to work before the CEL. A friend of mine said it had something to do with the V-tec, a sensor of some kind IDK.


Anyone had this issue before that could help me?

Tnanks in advance!

Wow, over 60 views and not a single reply??? This forum is total crap!

 

Sure, show up and insult us.

I spent a bit of time yesterday trying to find out what your error code meant, but was unsuccessful.

Just looked a little harder today and found this:
OBDII Code P2647 HONDA - VTEC Oil Pressure Switch Circuit High Voltage | HelpForCars.net

and this:
I have a Honda 2004 CRV - the repair ( OBD II) - FixYa

Sounds like something you really need to get fixed.

 

haha i think you got a lot of views and no replies either because people don't know the answer, or they don't want to put in the time/effort to look it up for you, when you could just do the same on your own.

 

Check Engine Light Documented: Rocker Arm Oil Pressure Switch
I was on the way back from a trip when my check engine light (CEL) came on. The car had been driving along nicely up until this—getting around 37mpg at 75mph. I have an auto SSM Sport model with ~33,500 miles.

There was no message in the information screen (the one under the fuel gauge), so I was pretty sure it wasn't just caused by the gas cap being loose. After the light came on, the first thing I noticed was that the cruise control became inoperable. Then I noticed that the car had far less power, and it even juddered once when the engine reached higher RPMs going up a steep hill. My fuel economy began to suffer slightly as well.

I felt comfortable enough to keep driving the car near the same speed, so long as I didn't let the RPMs surpass 3k.

I was able to make it to my destination an hour later, and took the car to a dealer the next morning. They said that the CEL was caused by a faulty rocker arm oil pressure switch. While I couldn't get confirmation from the dealer, I'm fairly certain that the car went into "limp home mode," which could explain the lack of power, fuel economy, and cruise control.

Luckily, another dealer nearby had the switch. Once the dealer replaced it (under warranty), I was good to go. Here is the actual description of what the dealer did straight from the work order:

Quote:
Customer states check engine light on since yesterday.
Scanned code: P2647 - Rocker Arm Oil Pressure Switch Circuit High Voltage, checked oil level was OK; switch internally failed.
Replaced rocker arm oil pressure switch, reset ECM, and performed VTEC test, operating correctly now.
Cleared codes during test procedures.
Part number 37250-PNE-G01
Everything seems to be running fine since then.

There's your answer be humble with Your Replys

 

CJYorrellas, first of all, check to make sure that your oil level is up to spec. That may have caused your code to be thrown. Did your friend clear the CEL? If not, try clearing the CEL, and check your oil level. If the code gets thrown again, then your V-TEC solenoid may be either sticking, or "fried."

 

And people wonder why I can be a dick sometimes.

 

im sure you wont be back to this site but there are 47,015 members on this site. 60 views is a drop in the buicket and not every on is going to know how to solve your issue.

 

Tell Honda, "Recall!"

 

X2!

My apologies fellas, didn't meant to offend anyone around here, I was kind of frustrated because I was searching for an answer to my problem and though I could get one faster around here, my apologies.

But let me share some knowledge with all of you and this one is very very important to all of you Honda Fit owners:

Error Code P2647 means the following:

V-Tec System Stuck On

I took the car to an Honda specialist, and gave me bad news. He said that Oil pressure is low due to the Oil Pump having some sort of internal valve stuck and this caused the V-tec system to stuck because it didn't received the amount of lubrication it needs. So thats why the car lights the CEL and doesn't accelerates beyond 4000 RPM because hes aware of the problem and is taking measures to avoid engine break. Also let me mention that under this conditions the car will wont allow you to use the Cruise Control.

He said that people think most of the time its the sensor its damaged when in fact its ok and is telling you that what is wrong is the oil pressure. He's gonna charge me 400$ because he has to dismount the oil pump and clean it to unstuck the valve inside. He will also check the head to verify if the rocker arms are ok because he said that further use of the car under this conditions can break them and further breaking the engine.

Imagine my frustration when he said that, my car is only 4 years old JESUS, how the hell this happened? Well he thinks that in my last oil change Pep Boys didnt used the correct oil in my car (although I checked the receipt and seems ok) and this caused the problem. He says this problem is frequent in Fits and Elements.

So if you ever encounter this problem dont waste your time and take your car to a mechanic before its too late, this can break your engine seriously!

Hope this info is useful to others around here, take care fellas!

+Rep for being classier than I in spite of the textual reaming, you came back to share what you found!

 

Sure no problem I hope this helps around here, IMO its valuable information!

Btw, can someone help me understand how things rolls around here? Is this forum moderated? Rules of conduct? Rep points???

 

I have a 2009 honda fit which use to give me 675km on a tank of gas in the city ,the salemans told me my mileage would inprove as the engine got broken in , two years later at 26000km on the engine it gets 450km on a tank of gas is that normal? What happens in four years ? 225km to a tank of gas? My 13 year old 1994 toyota tercel gave me 600km to a tank of gas , same size engine 1.5 litter and both atomatic trans. Has anyone had this problem and know what`s causing it ?

( News Flash ) I just learned that my K&N air filter could be the problem , because of the extra air flow causing the engine to give more gas also when I clean and reoiled the filter it gum-up the MAP sencer so I ran to canadian tire got a reg air filter some MAP sencer cleaner , MAP sencer is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. Although I think K&N air filter are great filters I would never recommend cleaning it, for best results put it in and forget about it until the end of time.

 

Sorry about your issues. Curious, what kind of oil (brand/weight/dyno/synth) Pep Boys put in?

 

Your conduct is great. I wonder about the moderation thing myself but everyone posting lately plays nice and you've already been +Repped.

 

If they put in reg oil thats not recommended that would do it.

 

I was reading another forum about the K&N filter problem that you have described and another guy and myself both agreed that though we have heard people say they had heard of this problem by way of someone who knew of someone else that had had sensor problems after oiling their filter, neither of us knew of an individual that actually had this problem In some of the K&N literature I remember reading years ago they said that a filthy K&N filter flows more air than a paper element filter that is brand new. At that time it was recommended that the filter be cleaned and oiled at 50,000 mile intervals.. I think using one for 50,000 miles and then chunking it might be feasible is you live in an area with high humidity that shortens the life of paper element filters... I use oiled cloth filters in all but my wife's Forester because of a service contract with the dealership but will put a oiled cloth filter on it after the last dealer service.... I periodically will remove and tap the filter on a hard surface to shake off loose stuff, give it a light spray of filter oil and let it sit in the sun until the oil has become sticky before reinstalling it. I only wash them in the Fall because of the amount of dust we have here in the Summer months but not every year do I do this.. I have been doing this on cars and motorcycles I have owned for about 25 years with no problems.

 

I agree with you 100% , I think K&N are wonderful air filters and in larger engines give you get better mileage and more horse power but in a econo car it gives you more power and consumes more gas which defeat the purpus of diving a small car, if I were to design a car for our Canadian winters it would be small lite have a very large engine be one foot off the ground front wheel drive that would pull you through any snow storm , great fuel milage because your engine would only have to rev low to pull a lite car , lots of heat because larger engines heat quicker ,the engine would last a life time because it would never be revved to the max, thats something that car dealers ,oil company's and car manufacturers don`t want us to have they would all lose profit but I know one day someone somewhere with the expertise and the balls will create this car and blow our socks off .
