Engine/Transmission (1998.5 - 2002) Tst keeps setting codes

[Black-Smoker]

My Tst Powermax 3 Comp keeps setting p0237 p0602 codes. I have all of the connections sodered and the ground going to the battery. I called TST and they said to put some dielectric grease on the map sensor plugs which I did but I am still setting codes. I need some help with this I dont know what else to do. The box seems to work fine and makes all kinds of power but it keeps setting codes.

I moved the ground wire to the bolt that the grid heaters are grounded to and this did not help. I e-mailed TST and I have not yet heard back from them.

take a look at your power too. the little fuse holder may not be making good contact with the fuse on one end or the other. also what and where you tapped the power. if you are piggybacking a fuse in the panel check to make sure that isnt lose or not making a connection. dielectric grease on everything you touch too.



its possible you have a bad harness for the MAP sensor or bad map sensor. have you taken the sensor out and cleaned it?



call up and talk with Mark or one of the guys in the shop.
