Bad spark plug made my check engine light burn on my 03 Frontier. The kid at the parts store correctly diagnosed #2 plug misfire but refused to turn off the check engine light. New set of NGK Iridium plugs cured the misfire problem and was able to turn off the check engine light with avatar666's very helpful tip.

Just did what avatar666 suggested on a 2012 nissan frontier sv king cab, worked like magic once I got it right ( after a few tries )... have all my power back and my stupid check engine light / system disablment fixed after the dealership screwed me over by spraying fluid film on my brake spring hold down clips ( which I had to wash off with WD40 ), under the guise of a ' brake inspection'... the adage holds true - if you want it to work, learn to mechanic it yourself

BTW, on the newer models, if you disconnect the battery, it doesn't get rid of the problem I corrected with avatar666s method - less than 24 hours is temporary, more than 24 hours lasts about 3 days... beware of connecting the battery without the key in it, as I got a nasty shock when the alarm started to draw juice... stupid computer nonsense...

Who'd a thunk. Worked on my 2009 Frontier. The light didn't flash, but when I cranked it up, the Service Engine Soon light was gone. Thank you….

I have an 03 Frontier. I tried this 3 times. Not sure what I am doing wrong, but it did not work for me. I plan to take it to an auto parts store and have them run a check on it and see if they can turn it off for me.


Disconnect the battery negative first then positive. Turnkey all the way until it feels like it's going to crank and leave it. Leave it for five seconds and turn key back off position and pull out of ignition. Reconnect the battery positive first then negative start truck no light.

I did what avatar 666 mention and it worked great on my 2006 nissan frontier (62500km) I did exactly what he mentioned and it worked good the second time. Thanks


Reset my light after getting the code and now the SES light is intermittently blinking. Did the reset again and still got the same code as before 1 1 4 0 and still back to blinking again. Any ideas of why this might hapen? Does it really mean there is a serious problem with the car as I have read in other posts? The car is running normal.

Worked like a charm first time. Avatar666 if you're ever in the Boston area drinks on me!

I tried this for months on mine and couldn't get it to work, then I thought how my car works and figured it out: FYI, if you have a manual transmission you need to hold down the clutch pedal also when you do anything with the gas pedal.

Worked first time on my 2004 Frontier! Thanks!


Mine did not work s Avatar666 suggested but mine worked as suggested by 211this. I just disconnected the negative battery terminal first, then the positive battery terminal. Then turned the key until it is going to crank, keep the key in that position for 5 seconds and the pull it out. Connect the positive terminal first then the negative terminal. Make sure lights are off. Start the car and the Service Engine Soon light went off.
