I have 03 g35 coupe was working fine went to jump it other day and is in limp mode now code 1122 and 1126 bought new tb and sensor still stuck in limp with same codes did some checking and found 5 bolts going to tb but idle is at 1.5 don’t now what to check next please help

 

You need to use a scanner that has has protocol ISO 9141-2

Those codes you posted are not supported by this ECM and your scanner is trying to guess what the code is.

Anytime you unplug the throttle body you MUST perform the TB closed position recalibration. Steps are in the FSM in section EC - Engine Controls, look at the start; of the document under "basic service procedures".

 

Ok what would be a better scanner I watched a video how to pull codes without scanner and did it and same codes came up with engine light flashing not sure I have tried to reset throttle I found I have no power going to my tb relay any help would be great thanks for the advise on different scanner

 

Check the fuse for the TB control relay. Fuse 87 in the IPDM.

 

Can you show me where that relay is going?
