I recently had the engine light go on code 52 knock sensor truck ran funny ect I was told on here to replace the pigtail of course I went to many parts stores in my area no one has one nor can order one This is the 3rd motor in this truck I do not know whether they disconnected the pigtail from the motor or wiring harness end. Reason why I am asking they seem to have about 6 different types of pigtails online I don't want to buy the wrong one My other question is the past few days there has been no engine light and truck runs fine is this truck playing games or just ignore it and just replace pigtail
