Reading Check Engine Codes - NO DEALER OR AUTOZONE REQUIRED!
 

http://mywebpages.comcast.net/jwelle...vice_cnctr.JPG


1. Jumper the service connector
2. Turn the ignition key to ON
3. Count the flashes on the instrument panel
4. Look up what the code means

the flashes will be a series of long blinks, a pause, followed by short ones. For example:

Long-Long-Long-Long-Long-Long-Long____ShortShort

7 long and 2 short, indicates a code 72, Cyl #2 misfire.

Once you've got the code, you should have a pretty good idea of exactly what the problem is. You can troubleshoot from there.

after putting my oil pan back on my 98 V6 accord I started it up and the check engine light came on. I used a paper clip and the above method and read a code 65... Secondary O2 sensor. Apparently while moving the exhaust to get to the oil pan I accidently pulled out the connector for the O2 sensor for the catalytic converter.

Reconnected it, reset the ECU and the check engine light went away!!

I didn't even have to leave my garage!! :D

This belongs in the ARCHIVES!!!

Good info!

Very nice. I agree... put this in useful topics asap!

I third that.

BINGO...good job...st-st-st-sticky it

The good old paperclip and count the flashes works on most OBD cars. Just gotta find the documentation for what the codes mean.

Great Reference :thumbsup:

excellent post bro... :thumbsup::thumbsup:

Awesome post. :nod:

I found it v6p.net while looking for a way to reset the check engine light.

Even though my asian honda tech would check it out for free I was happy not having to drive anywhere.

I'm sure it will help someone!

i just use this
http://www.davisnet.com/productpics/big/8220_Keys.jpg

plus i can get a bunch of other info out of this thing too like
RPM
Throttle position
Engine load
Fuel pressure
Fuel system status
Short- and long-term-fuel trim
Battery voltage
Timing advance
Coolant temperature
Air flow rate
Intake air temperature
Intake manifold pressure
Oxygen sensor voltage

all for less than 200 bucks

WOW ... That is fuckin beautiful :bow:

info? link?

Here is a "free" reference lookup site. You just put in the OBD II code in, and it will return with a definition. (BTW, it's free, so if it doesn't find some oddball definition, remember the cost...)

Off to the archives...

JackCL can you view the info from the carchip in realtime. Or does it have to be downloaded to a pc.

Okay i've been trying to do this but the flashes I get don't correspond with anything listed. I get 5 long flashes from the Check engine light. I also get flashes from the ABS light. 9 longs _ 3 Short... then 3 longs_ 5 short


Help :( :dunno:

Great... Service Connector?
 

Wow all fantastic stuff...

OK but the thing is I can't find the service connector.. :dunno: I'm a pure newbie. I just bought this car 3 weeks back with 105 K miles on it. And right after an oil change at walmart my Check Engine light came on (10 days back)

I read this post and some other ones and figured that the service connector is behind the glove box somewhere but I couldn't find it :dunno:

Can someone help please?

Thanks...

It is between the seat heater switches, under the 12v accessory. You remove a small plastic cover.

Sorry I guess I forgot to mention it's 97 CL 2.2 Premium... it doesn't have heated seats. But anyway I couldn't find it under the 12 v accessory...

Opps.. then I have no clue.

i got a po130 code so wat exactly am i suppose to do? i checked the o2 sensor behind the catbak and it looks fine, but the check engine light is still on. it came on after i got my exust system changed... is the primary o2 sensor the one in the front or the one in the bak? i'm a total newbie so any help would be very thankful... oh yeah... and i have to get my car inspected soon u think i would pass with the check engine light on?

Just to let everyone know:
Code 16 (1L6S) = missfire

I had to pay the dealer to find that out.

do i need to put the paperclip in the specific holes as pictured or can i put it anywhere?!!? THIS IS GREATTT THANK YOUUUUUUUUU

i think its under the dash on the drivers side.

It's been probably posted somewhere on the forum, but could be useful here.

Last week a Check Engine Light came on while driving. My car has 39k miles.

Some 500 miles ealier my tank cap was stolen on Shell :whyme:

I bought there a new one, but as it turned out later it didn't match perfectly to the inlet. I used a tape to seal it - to no avail. According to owner's manual, after 3 trips the light should die out after sealing the inlet.

So I did a test described above.
It showed misfiring on all 6 cylinders !!

If it was true the car would shake like an old diesel during startup and immediately die. My car was driving fine. I was almost sure it was related with improper fuel cap and emission systems.

So I simply disconnected the + from the batteries, went to work, reconnected it and the Check Engine Light didn't flash anymore.

I did it al after a consultation with an Acura employee.

In majority of cases CEL shows up just to bug us that emission system detected some slight "deviation".

Greetings

PS. Of course I need an original Acura tank cap.

Hi everyone! I'm a newbie to the board and just picked up a 2003 3.2 CL Type-S, MT after losing my jdm fronted, turbo'd integra in an accident.

Anyways, the CEL just popped up so I'm trying to pull the code but can't locate the service connector. I believe I've found the OBDII diagnostic connector under the dash on the driver, right side, but is there a 2-pin service connector that I can jump with a paper clip to pull the code like my old Integra did? If not, is there a way to jump the OBDII connector w/o shorting anything out? The pics are dead in this thread.

Thanks!

which pins need to be jumped?
is there a link to a list of error codes?

thanks!

does anyone know which pins? this is the only thing i could find on google and the pics are dead...

found it:

IT'S PINS 4, AND 9

THIS COVERS ALL OBDII VEHICLES.

TURN ENGINE OFF FIRST.

Nice job searching :thumbsup:

However, the k-series forum link says to pull fuse #6 in the engine bay fuse box. In the CL, it is fuse #13 in the passenger side fusebox, a 15amp fuse for the clock. You will not lose your radio presets this way, but you will need to reset the clock.

Ive got an old bluetooth OBDII reader that doesnt work, Im going to strip it and jump those two connectors so I can easily plug in whenever a code needs to be read.

nice job but basic scanner costs like $25-30 shipped on amazon i would be to lazy to go there jump it and count the flashes but for each their own and DAMN you got a thanks from RonA ohhh god im so jealous !!

Had my transmission replaced with an 05 Honda Oddessy and when I got it back yesterday my CEL was on. I used the pull the # 13 fuse method and it worked! Thanks for the help.
