Searched without any luck.
Replaced #4 GP twice and still get the SES light back after a few starts. GP checks good and voltage to plug checks.
So I am thinking its the controller but I cant find any test procedures and at $130 for the part I don't just want to try swapping without knowing its the problem.Hope its an easy test with volt meter I don't have a fancy scanner and the ones at the parts store just give fault codes and its #4 GP
