hey guys..i need help....my check engine light just popped up last night as i drove....all felt good as i kept on driving..
i looked at my repair manual to check out the ECU codes....but really looks complicated to just get the code itself....
i thought it would be like my 1990 accord that just had a series of blinkin lights on the ECU and just count how many times it flashed.....
but this sentra ECU looks trouble sum....
ANY EASY WAYS TO DO THE "HOW TO" WAYS ON PIN PONTING THE ACCES CODE.....OR SHOULD I JUST TAKE IT IN TO THE MECHANIC SHOP???
and is the ECU under my drivers side floor under the seat??
1992 SE-R check engine light

ECU's under the dash near the accelerator.
Autozone used to pull codes for free, I know mine does to this day, but I've heard of them charging.
There's also a pedal procedure:
From the driver's seat...1) Turn the ignition key to the ON position and wait three seconds. (Do not start the car.)2) Fully depress and release the accelerator pedal five times in less than five seconds.3) Wait seven seconds. Fully depress the accelerator pedal for ten seconds until the MIL light flashes.4) Release the accelerator pedal and 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 itself until you turn the ignition key to the OFF position, at which point the ECM resets itself to standard drive mode.
You can look up the trouble codes in the ESM/FSM (link to get one is available in my sig); 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.
Clearing
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).

Re: (nametakennow)
sweet..thanks a lot.....so under the dash huh...not under the seat????....for my 1992 sentra......
Re: (nametakennow)
I tried your suggestion on my 2002 Sentra, but it didn't work. Is there a different procedure that I can use to get the trouble code? My service engine soon light has been on for a few weeks now.
Thanks, man.
