What year car? Title says 02, post says 04

Trim level?
Body style?
Country?
Engine size?
Trans?

you've posted about several different cars in the past....are you a mechanic working in a shop?

and post history suggests a 2001 dx sedan. Another post says 2002 DX AT.

Picture OP posted "verifies" a D17A1 under the hood.

Hi,
I am from canada and not a mechanic at all, i am just newbie who want to learn how car system work. i watch video on youtube, see the parts name, visit different website etc.
when i have problem with my car i come here to share with you and solve my self if possible.
and increase my knowledge because of you guys.
We have 1 Honda civic 2002 4 door sedan DX automatic transaxle
and one Ford freestar 2005 sport with automatic transaxle.
why this website because i dont see any good website where i have reply on civic from canada so i came here and now use too to be here.

gulzarh

what?

gulzarh

Honestly before i didn't what year car i have but now i am sure it is 2002.

I scrolled through your post history to verify what kinda car you had. You posted a picture from under the hood, and the characteristics of the engine pictures shows that it's a D17A1 (2001-2005 civic dx/lx engine).

gulzarh

ah ok ok i understand.
but how did you found it is D17A engine. i didn't see this word anywhere?

It was this picture I used to determine that you have a D17A1 engine


and these reasons:
-Wire cover on the top (that says Honda) does not say "Honda VTEC"
-Exhaust manifold has an O2 sensor sticking out the front, denoting the catalytic converter is integral to the exhaust manifold, and the aforementioned O2 sensor is the upstream one. The D17A2 (ex) has the upstream O2 sensor forward and below the engine since the cat is located underneath the engine.
-No VTEC solenoid present on the top left corner of the cylinder head.
-No EGR valve on the left side of the engine (though this isn't 100% indicative)

If you look about 8-10" down from the upper radiator hose, you should see "D17A1" stamped on the engine. Using the picture as a reference, pretty much straight down from the O2 sensor pigtail connector.

wow you are genius and have big knowledge. bravo

so anyone interested in my civic problem??

The definition of the P1519 code in your scanner is incorrect (and brings into question the validity of all code results)
That's what made me ask what car you have, and I wasn't in a place to look up the actual definition of that code. I might expect an IMRC system to be found in a K engine, but never in a D engine.


Anyway....


P1519 is defined as "IAC valve circuit failure". The PCM believes the IAC valve circuit has incorrect resistance which might mean a bad winding, or it may be as simple as someone forgot to plug it in.

NOTE: Mice love to eat wires.






P1457, EVAP system leakage, canister system. Many, many possibilities, some of which are not leaks at all.
Need understanding of how the system operates, how it is tested, and ability to 'watch' tests in real time.


It is common to find the CVS valve badly rusted, causing leakage in the canister side of the system.

01-03 are susceptible to purge valve failures (restriction) that can cause fault codes for either of the tank/canister systems.
(NOTE: Again, mice love to eat wires...this valve is on the throttle body right next to the IAC that has a fault code)


There are a couple service bulletins for EVAP related code issues with rather obscure fixes too.

Check fuel cap, make sure its gasket is not cracked or hardened, but I don't think it has anything to do with the code you have.

P0420, catalytic converter efficiency below threshold.


I might erase codes and see what returns immediately. The IAC code may return immediately.
The EVAP code may take a few days to return, as would the cat code.

gulzarh

for the two last i am not very worry but
for the p1519, it come as soon as i erase it but the other take a little time max 1 hours.
i should buy a new valve or i can clean it also?
i have clean throttle body at least 3 time this years without removing it completlyy from the system.
we dont have the mice in our house or near.
another thing, you mean there is no IMRC in my car and what are k and D engine?

Read this very carefully:

P1519 is defined as "IAC valve circuit failure". The PCM believes the IAC valve circuit has incorrect resistance which might mean a bad winding, or it may be as simple as someone forgot to plug it in.


Actual inspection and testing may be required to determine what the correct repair will be.







The IAC code number in your code readers internal 'library' is incorrectly defined as IMRC. The number might be right but the description it told you is wrong for that number.


D is the engine in that year Civic (D17A1 or D17A2) These engines are not equipped with IMRC.

K20/24 engines are in cars such as the Civic SIR (Canada) SI (US) and some Accord/CRV/Element and more. Many of these do employ IMRC.

gulzarh

how should i test it to found where exactly is the problem?
if i understand correct we have either iac or imrc but not the both in same car, van or truck?

ezone

Follow troubleshooting instructions in a service manual


The code P1519 is for the IAC valve circuit.

The end.
Stop.
IMRC does not exist in your car.

gulzarh

if i have service manual why i should come here,
its ok bro dont take headache it is was simple question.
Thanks have a good night

Check resistance values of the IAC valve
Check continuity of wiring from the IAC valve to the origin of each wire
Check power/ground/control signals on each wire
