Need a little help.

TPS low voltage code P0122

1. I replaced TPS sensors with new.The issue was better for 2-3 min and then i contined to have erratic idling and poor drivability. Puttering and loss of power. Also vtec does not engage all the time. When it runs good it does and when it bogs out and studders v-tec does not engage.

I have tried adjust angle of the TPS as well.

I need the wiring diagram or need to know what color is the signal/power/ground to test the wiring.

Any help would be greatly appreciated.

 

Yel/Blu: +5v ref (C28)
Grn/Blk: Gnd (C18)
Red/Blk: Output (C27)

 

Thanks for the help.

I checked all the wiring and then....

I installed and adjusted it to .5v at closed throttle and 4.5v at WOT.

The car ran really good for approximately 3-4 runs and then would not engage in vtec and began to idle somewhat high.

I havent got to check it out yet but I assume that the TPS which on my 2000 Si is held in by two screws has moved a little causing the closed/wot settings to be off but not as bad as they were. I believe that the flat head screws dont allow you to tighten it enough and the throttle shaft causes it to shift.

I read the code again and came up with a P0122. I didnt bring my multimeter home from work so I will check it tomorrow.

I just wanted to post maybe this will help others with the same issue.... I believe my old TPS was good because I am having the same isssues with the new one. I will confirm this tomorrow and repalce the flat head screws with allen head, torx or regular bolts which will allow me to torque them and not allow any movement.

 

Still having the same issuse p0122.

I have

-5v
-ground
-.5v-4.5v at the TPS and ECU.

Checked all wires for continuity. Is it a ECU issue?

 

When does the code actually come on? First thing after you start the car? During some sort of driving conditions that are repeatable?

 

I had a P-0122, it was due to changing my throttle body to Skunk2 and the bolts lossening up lil.
After much reaserch. i just thighten them up and im good to go.
