I got P0507 and SES light on

Please help me figure out what's going on with my 2002 Altima (http://www.automotiveforums.com/vbulletin/../#) :confused:. Since I bought it I have p0507 but car run good with the properly idle around 1300 rpm until that' warm,when the coolant reach the regular warm temperature idle is regular around 900 rpm. I tried to disconnect both battery cables and touching them together to erace error, also tried doing that set sequence where you cycleing key on for one second and off for 10 seconds three times, pump the gas 5 times, etc etc, wait till MIL light goes of, I took of throttle body ceporate, clean and put it back just to avoid problem with stacking throttle plate. But I didn't obtain results. :banghead: Someone know how fix this problem. Thank you.

Have you tried to reset the code with the reader you were using. Since you cleaned the throttle body I would reset the code and hope it doesn't come back.

I did it couple times but it coming up again. I went to Nissan center, they checked my car and told me nothing. Mechanic said: it might be throtle body but I'm not sure.

Problem Fixed

Had the P0507 flu for weeks. I attempted throttle valve learn, and it would not work. Took it into AAMCO up in Mesa, AZ for help. The mechanic said it's either an intake leak or my Throttle Chamber is damaged and needs to be replaced. No leak on the intake, but it was the Throttle Chamber. 389.00 later, the problem was fixed through a nissan dealership. The problem was the idle switch. It was damaged and could not be replaced by itself. I had to buy the entire component, which was the throttle chamber. This is also why the throttle valve learn would not work. I must have tried that, at least four times before giving up and taking it into AAMCO. This part can only be bought through a dealer, so good luck. Idle speed is normal now.:licka:
