Question

Code P1168 on my 2005 Nissan Pathfinder 4.0L ECM was changed for recall NTB10-137 and now the Needs Service Soon light is on.

The "Service Engine Soon " service light is on after ECM was replaced in the recall. Is this connected?

Answer 1

The service recall NTB10-137 instructions do not require the replacement of the Engine Control Module (ECM), the recall only requires the replacement of the ECM relay. It's possible that the light is just a coincidence. You need to find what code is triggering the "Service Engine Soon" warning light to come ON. You need a scanner to check for codes.
