Found the code p1122 and while trying to press on the gas pedal there was no comunication to the throttle which the car would go or the RPM will rise up to 2000. I replaced the throttle body control unit and the problem was fixed.
-
Thanks for letting us know. The throttle body is indeed a very common problem.

Hi. I have a 2004 Nissan Sentra 1.8 M/T. Service Engine Soon light came on and I rec'd a P1122 code. I cleaned the throttle body; however, that didn't seem to work because the light is back on, and now my car idles higher than usual, not consistently; but, enough to notice. Where should I go from here? Replace the throttle body? Try to clean it again? Something else that I'm not looking into perhaps? Please help!

Try performing the Idle Air Volume Learning procedure to reset the engine idle.
Instruction here: http://nissanhelp.com/diy/s...
You may have to perform the procedure a few times. If the problem persist you may have to replaced the throttle body.

Ok my 02 altima is throwing this code p1122 and some.others also p1126 p0123 p0223 p0507. I replaced my crankshaft sensor and throttle body. Somebody! Anybody! Help me out. This has been kicking my butt for about 2 months. The problem is my rpm wont go past 2000 and while in gear it won't go up at all. And after a little while of running the car the engine will seem like it's overheating. And the car begins to *put put* and shake almost like an at or dirtbike when it's not getting gas and is about to cut off! Some one help me!
-
There are so many thing that can cause the code and some test needs to be perform to find the exact problem. You could start by clearing all the codes to check what code comes back first and try to fix that code first.
I had a vehicle with a similar codes and symptoms and the problem was the IPDM (fuse box unit in the engine compartment) ( https://www.autocodes.com/glo... ). The IPDM is what powers the Throttle Body.

Hello everyone,
Please I also have this trouble code p1122 and p0135, with my Nissan Tiida 2008
Sometimes when I am driving I suddenly lose throttle power, and the car start crawling, even with the throttle pressed down engine just idles with no response and power to the engine , and sometimes when I turn engine off and on, its ok again for awhile and start all over again.
Now, I cant even start the engine, as engine tries to start so erratically.
Please help!! Any advise or recommendations? -
Codes are not related. The P0135 code shouldn't cause any drivability problems. More than likely the problem of the engine performance issues is the throttle body. You may have to replace the throttle body, but you could start by cleaning first.
-
Thanks will give it a shot, anywhere I can purchase throttle body online for a fair and good price? thanks again

What year is your Nissan? The throttle motor is part of the Throttle Body, which is what the code is for. More than likely you have to replace the throttle body to fix the problem.

-
If you get the P1122 code, combine with the symptoms you mention, then the problem it's more than likely the throttle body.
-
2005 Sentra specv. Idle fluctuation 1500-2000 rpm. Installed new throttle body and problem persists after relearn using scan tool. Any suggestions?
-
Unfortunately you have to have the dealer, or any one with a Nissan Consult reset the idle for you. You could also try disconnecting the car battery for over 1 hours and try turning the ignition switch ON and OFF several times.
Another way you may be able to do it, is by disconnecting one ignition coil and performing the idle relearn procedure, the reconnect the coil and do the idle relearn again.
I hope that helps.
-
hi I have the code p1122 and I already check for any bad wiring and the fuses as well I already installed a new throttle body and I did the relearn so many times and the problem is still there I put the car in drive and I press the gas with the ignition on and I can hear the throttle vale open and closing so im really stressing I need my car for work please please HELP ME OUT THANK U

2005 Nissan Sentra. No signs of any problems or symptoms? But check engine light came on

The P1122 code, means that the throttle body failed to response or didn't work as expected. You should start by cleaning the throttle body and clearing the code.

I have a 2005 Nissan Almera. Symtoms occurring were engine showing codes P1122 & P1126. Engine reving only to 2000 rpm. After changing accelerator pedal sensor, cleaning Ethrottle body & changing Ethrottle body, codes were still showing. Finally, we changed the throttle body motor relay, & problem was rectified.
-
Where is the location of that throttle body motor relay i been looking everywhere i only have one blue relay and a gray one and like 4 or 5 Brown ones i only have code 1122 maxima 02 n i already bought a new gas pedal and throttle body
-
2002 Nissan Maxima the "Throttle Control Motor Relay" is on the fuse box in front of the battery. (Yellow color of the relay is just for illustration, actual color is different)
-
So then what's the correct color to that relay for the throttle body control motor relay
-
Color of the relay is not important, look at the location of the relay. I just wanted to make sure you were not looking for a yellow color relay.
-
I bought the car used from a guy and it doesn't have the cover where it says the location of it that's y its been so hard to figure it out witch one it is ..because i looked and one picture says its under the dash by the driver side
-
This is my relay box. The relay for the throttle body motor is the bright BLUE one on the right at the top. I changed this relay and the problem disappeared
-

-
I have a 03 nissan sentra spec v i bought the car a month ago and have replaced the tb yesterday and the car still has a rpm problem it revs from 1500 to 2000 sometimes when the motor is cold it revs to 3 i had a obd connected and it says tps has a high voltege problem now i am tracing the wire the best i can to see if anything is touching frayed or something but my car also has a code for crank postion senser and something to do with my evap i even had the guy do the idle relarn on it and it still didnt do nothing at all not really trying to take it to a nissan dealership and spending 500 for them to tell me that it was a simple fix ya know i rather do it at home do you have any advice or anything that it could be? And could this possibly damage the car if it goes for to long and the car has 183k
-
I'll start by performing the Idle Relearning procedure several times.
Instructions here:http://nissanhelp.com/diy/s...My opinion is that the idle learning procedure was not properly done.
You won't damage the engine if keep running at high speed, but the MPG will definitely go down.
-
I have Nissan sunny 2010 I cant find the etc motor power relay I need help
-
I have a Nissan Sunny 2003 (FB15).
After starting the car it won't accelerate. it happens very often.
Then after warming up and restarting the engine for several times it fixed itself.I got the error code P1122 initially and P0100 later.
Any suggestions? -
The P1122 code means that you have a problem with the throttle body. You could start by cleaning the throttle body (if you do that make sure you disconnect the car battery). If the problem persist after you clean the throttle body, then you may have to replace the throttle body to fix the problem.

My Nissan March suddenly stopped and when I tried to start the engine it only moved in idling and it lost the revs. The fault code showing was p1122. I tried to replace the throttal body but nothing is happening. When press the accelerator just a very small sound of the revolution is heard
-
I'm wondering if this can also effect the Transmission if it persist?
-
It's possible. The transmission needs the throttle body input to shit gears.

I have a Nissan Sunny 20013
After starting the car it won't accelerate. it happens very often and shows Engine Check Sign
Then after warming up and restarting the engine for several times it fixed itself. -
En donde se encuentra el relevador del cuerpo de aceleración? Me pudieran apoyar tengo un Sentra 2003 ya cambié el cuerpo de aceleración y x un tiempo jalo perfectamente pero al poco tiempo volvió a aparecer el código p1122 ya reemplace el pedal y el cuerpo nuevamente y volvió a funcionar sin problema de esto tiene 20 días y hoy otra ves el problema solo se mantiene en ralenti
-
Si ya cambio el Throttle Body y el pedal y el problema sigue, entonces el problema puede ser el ECM o el Throttle Body Relay.
