Yesterday while I was driving my car lost ALLLLL it's power. I couldn't go more than 5 or 10 MPH. At the same time my Service Engine Soon, VDC OFF, and SLIP Light came on at the same time. I took it to Nissan today.. they said I most likly need a new throttle body..

The codes are:

P1122....P1121....P2135

Has anyone had this problem before? any other suggestions. Thanks in advance!:confused 2:

 

my car sat in storage for a about 5-6 months and wasnt driven much before that and when i got it out i had this problem once and these codes..i took the throttle body off and cleaned it and put it back on and cleared the codes...that was 3k miles ago and no problems since. i beleive my problem was just from being dirty and sitting..id try to do a good clean and go from there. u can find the diy on here...if that doesnt work then yes id get a new throttle body..

 

Update. I went ahead and ordered a new throttle body.

I also went out to turn my car on, as soon as I turned the engine it it turned right back off!!!! And again as again... What could this be?

 

did u put the new throttle body in yet? id try the idle relearn procedure

 

Nahh the new throttle will be here in about 2 days.. I had to order it. Is there anything else this problem could be?? Maybe MAF sensor.. Etc

 

id clean the maf with some crc maf cleaner but its probably the idle relearn procudure that needs to be done

 

You could have cleaned the throttle body yourself and maybe save yourself a couple hundred dollars if that was in fact the issue.

 

^^agreed..def. worth a shot before buying a new one..worked out fine for me..common problem with these cars is the throttle body getting just gummed up and dirty causing idle issues and problems like this

 

Clean the MAF. Clean the throttle body. Do the idle learn reset and trottle body reset and ecu reset. Guarantee your problem will go away.

 

hey guys just wanna leave some helpful advice so you guys dont blow a bunch of cash with this kinda related problem.

i have a 04 g35 sedan with the limp mode problem so i check the codes and get the throttle motor code so i erase it boom cars runs fine untill you turn it off.

turns out the relay was so corroded with rust no wonder. ok so i clean the terminals with a lil sand paper. next day fricken car would just turn over and not fire, im like wtf. do yourself a favor and just buy new relays from digikey and replace em all they're cheap like 5 bucks i think its a cm1 33201 12v spst.

hopefully this helps someone down the road. cheers
