Need Help, Code P0606 after HTB2 Install

[KOOPDADDY]

Just started up the truck and I got code P0606. Can someone please ID this for me.

Code P0606= Internal ECM processor

This can be caused by having a fueling box, and getting on it too much when the motor is cold.

Actually, I cleared it out and it was still there. I then took off my TST box and guess what, I cleared it and sure enough it was gone for good. Another TST box bites the dust.

hey KOOPDADDY,



Do you guys have a dyno at your shop? I need to dyno my truck to see if the Bullydog Power Pup is working and putting out BIG power on my truck.

 

[KOOPDADDY]

Transmission dyno only, sorry.

I had this same problem, except my engine light wouldnt come on but the code was stored.



To fix it I moved the ground wire from the neg. battery post and put it on the dash skeleton. All has been good since.

Thanks, I will try that

I've had that code with my TST box since I got it. No problems, no CEL, I don't worry about it. IIRC my ground is on the battery, I may try moving it.
