hello guy's i was thinkering around with the hypertech and the shift points, and the hypertch gave some dtc. Can sombody help me with these codes,b1045, p1516, b1055, p0137. p0420, p0430. any help would be apreciated thanks.

 

if you go to autozone they can tell you for free. they even sell the book that tells you what they are

 

p1516-tac module throttle actuator position performance
p0137-O2 sensor circuit low voltage(bank 1 sensor 2)
p0420-catalyst system efficiency below threshold(bank 1)
p0430-catalyst system efficiency below threshold(bank 2)

I pulled these codes up from my dyno-scan. I do not have any "B" prefix #s.
Sounds like you certainly have some issues. I still would check with Autozone as they will pull these out for free and reset.
Hope this helps some.

 

did you just put the headers in recently??

 

thank guy's I took the cat's off resently
