All you ever wanted to know about your Check Engine Light but were afraid to ask - Page 8

I tried doing everything in the the directions and I can't get the light to blink or whatever. Any ideas on what I could be doing wrong?

Also, for some reason my heater/blower only works when its on the highest setting (4)...does anyone have an idea why that would be and how much it would be to fix?

I heard there is a recall I think on the ac ducts. Try pushing the peddle more firmly and maybe putting an extra second in you timing here and there. I never get it on my first try and I've done it several times.

How do I find out if the recalled ac duct has already been replaced?

If you can't get the CEL to flash the code, you are missing the timing of the steps. Be sure to take a watch that displays seconds, and be as precise as possible.

JK, I've got a 2002 with a no spark at plugs problem. Just curious, what year Altima's does this procedure apply too?

Thanks for your help. Four Z'z

This works on my 02 Altima, which I think you said you had.

Call the Nissan service dept and give them your vin# they will tell you all the recalls you've had and still need.

JK Just wanted to thank you for posting the procedure to read the DTC code. It worked great on my 2002 Altima. The code (0340) indicates that there is a problem with the CMP sensor. I'm hoping after the dealer stock is replensished it solve my no spark/no start situation.

Again, thanks for spending the time to post the information.

Thanks for the information. I'm looking for a manual for my 02' Altima,can you help?

doec2k · Jan 25th, 2005, 06:46 PM

Question where do I find the error code list. I alread have the code(0455), but I don't know what the error code mean. Can you help?

This is how you reset the check engine light. No tools required!

In car ECM Diagnostics/ECM Reset procedure:

1) Sit in the driver's seat.
2) Turn the ignition key to the ON position and wait three seconds. (Do not start the car.)
3) Fully depress and release the accelerator pedal five times in less than five seconds.
4) Wait exactly seven seconds. Fully depress the accelerator pedal for ten seconds until the MIL light flashes.
5) Release the accelerator pedal and start counting flashes to obtain the four-digit trouble code.

Long flashes (0.6 seconds) indicate the first digit of the code; count the blinks one through nine and write down the first digit. (Ten blinks indicates a zero.)
The next three digits follow in turn in the same fashion except with faster blinks (0.3 second) and a 1.0-second pause between digits.

The ECM code repeats intself until you turn the ignition key to the OFF position, at which point the ECM resets itself to standard get-in-and-drive-the-car mode.
You can look up the trouble codes in the ESM/FSM; there's a bunch of them. In the ESM, refer to page EC-639.
Additionally, if you get four blinks of ten (0000), the ECM is indicating no malfunction.

You can clear the code (and the annoying MIL) by holding down the accelerator pedal for more than 10 seconds while in Diagnostic Test Mode II. When you release the pedal, the ECM erases the trouble code(s).

Good info. I'll save this for a future nightmare.

ittamaticstatic · Feb 18th, 2005, 01:43 PM

Sure thing man. Also I herd that you could do this before getting your car inspected and you should pass if the light doesn't come on during inspection. I know that when I didn't have my second o2 hooked up for a while and I cleared the code it took like 100 miles for the light to come back on.

Are you sure that the proceudre for the check engine light diag works? has anyone else tried it as I did and came up with nothing. Wouldn't be easier to maunally get the codes out of the computer with the turn of a screw?

ittamaticstatic · Feb 24th, 2005, 06:30 PM

Try puching the pedal fermer. If your timing is off one second at any time then it will throw it all off. Plus at the end when you hold it for 10 seconds, just hold it till it starts to blink then let off. It usually takes me anywhere from 3-4 or 10 times to finally get it. You have to so damn accurate it's almost annoying.
