Question about 2004 Nissan Sentra 1.8

Open Question

2004 nissan sentra throttle control motor relay

I initially couldn't keep my car running, getting code P1126 and I believe it was P1122 or P1121. Checked the code meanings and they were "throttle control motor malfunction" and "throttle control relay malfunction". Re-tightened the engine ground straps and now car will run but only idle, pedal can be pushed all the way to the floor and car just idles, engine rpm does not increase feels like nothing to the gas pedal. Tested and found no power to the throttle control relay harness, is there a fuse or fusible link associated with this unit? If so where is it? Also following the harness to the passenger side firewall there is a black box taped up in the harness of some sort, do you know what this is for?

Write the codes down. Then erase them. read the codes that come right back, before you start the car. If the U codes come back, these have to be addressed before anything else. Communication codes. If not, Drive the car for about fifteen minutes and read the codes again. These codes have to addressed first. One code left on over time can cause other codes.

How do I reair this code


1122 is either the throttle position sensor or the mass air flow sensor. One of them is bad and will need replaced. I would lean more to the mass air flow sensor.
1126 will probably go off when you fix 1122.
