Ok, a while back after i rebulit my eng and put a new eng harness on it i was getting code 52.

So my question is this.

could it still be a wiring issue or do you guys think its a bad sensor. ive been lookin around on here and only thing i could thing of is maybe a bad ground. where are the grounds at that would effect this system at. because, im sure all the grounds were on but i may have missed one if there are any by the ecu.

I just wanna have the neccasy parts waiting for me when i get home to fix the problem is all... thanks in advance guys!
