How to check codes without a code reader, and clear them

To any and all that might be interested, you can save yourself a trip to the local parts store and check codes at home. Find yourself a watch with a second hand and do the following...

---Make sure car has been off for at least 15 minutes.

---Turn ignition switch to 'ON', not running

---Wait 3 seconds

---In the next 5 seconds, fully depress and release gas pedal 5 times

---Wait 7 seconds.

---Depress gas pedal and hold down

---Watch SES (Service Engine Soon) light, it will start blinking

---You can release gas pedal at this point

The SES light will blink out the code/s that are stored in the memory. They all have a 4 digit number. The first digit of each code always blinks slow, followed by a short pause, quick blinks for second digit, short pause, quick blinks for third digit, short pause, and quick blinks for final digit. If more than one code is stored, the computer will blink each in numerical succession until done(it starts over at that point).

Couple of notes on the blinking...

---ten blinks for any digit ='0', zero
---code '0000' means all clear
---add a 'P' in front of the code number when searching for results

The codes can be cleared (and SES light turned off) from the computer while in this diagnostic mode. While the SES light is blinking, simply depress and hold the gas pedal for at least 10 seconds, release pedal, start car. The SES light will go off and stay off if problem does not persist in car, or if repair was completed.

Hope this helps...

thanks for the tip. i have not had an ses light come on yet, but now i know how to check it out. i liked my old srt4, turn the key on and off 3 times and it would tell you the code where the odometer usually is.

thanks again.

Or just get a OBD Reader from Mac Tools for $60 and you don't have to spend 20 mins trying to figure out codes. Plug into OBD and run the codes.

my SES light goes on and then goes off. In other words, it stays on for a couple of weeks then goes off for a couple of more weeks. ITs been doing this for a long time now after I installed my new MAF and new o2 sensors.

Nothings been wrong, it still scans the code, but if it keeps going off, maybe nothing really is wrong and i should restart it?

Has anyone else had this problem?

See if you can pull a code anyway with the instructions above(there may be one stored, but light may be off...called a temporary code). I have also read that in the case of replacing the MAF, the code will not always clear, and may need to go in and be reset by Nissan. If there is a code, shoot me a PM, and I'll look it up for you.

BTW Mike, I really ought to shoot you...It all started with the blue light in the ignition...Now my damn wife(screenname Ethel) has me adding LEDs on the exterior and interior of her car...LOL

You asked, I answered, bad bing badda boom So it worked out eh?

As for the code, Ive always been getting the P1273 (i think thats what it is) air flow sensor code. But now theres no problems, Ive replaced all the sensors and MAF. How much is it to get it restarted by Nissan?

Yes, it (lights) worked out...grrrrrrrrrr

On to your problem. That is the code that I had when I was running without a cat, and my rear O2 intercept was not working properly. It is one that WILL stay locked in the memory. It can refer to the MAF, but can also be caused by the rear O2 sensor as well. There is actually a TSB out stating as much. It is probably still sitting in the temporary code memory.

Try disconnecting the battery overnite(will drain and clear ECM, and also the the short term memory). If that doesn't do it, you may have to take it in to get it cleared. As for $ to clear, I truly could not tell you.

Well this method did not work on my 99 altima, but I used my previous method used on my ex 200sx, just as handy info, the ECU lastic black cover on the dirvers side is teh one that should be taken off to get to teh ECU and pull codes manually like here

Has anyone else had this problem?
The DTC protocol is that if the ECM detects a problem it stores a 1st trip DTC. If the problem recurs in 2 consecutive driving cycles [which have a strict definition as far as the ECM is concerned ,ie.every time you drive your car does not necessarily constitute a "driving cycle" to the ECM] then the SES light comes on. If the problem does NOT occur after the SES light is on for 3 consecutive driving cycles, the SES light will go out but the code is still stored as a 1st trip DTC. If the problem recurs the SES light comes back on.It takes either 40 or 80 cycles [depending on the problem] without a problem to completely erase the ECM memory [unless you intervene and erase it]. Hope this helps explain your situation!Download a copy of the fact. serv manual. If you spend a little time there is a lot of helpful info. in it.
