I got a check engine light.. took it to Autozone and had it scanned and came up with the code P1680. They guy said thats a dealer code, that he couldn't tell me what that was. I looked around online and all I can find says "DTC P1680 = Driver 5" What is driver 5? Sounds like a PCM problem, no? Anyone know?

Thanks for any help,
Craig

 

I can't find any reference to that code in GM sources. It shows up as a Chrysler code. Are you sure it wasn't P1860 = TCC PWM Solenoid Circuit Electrical?

Shoebox has the LT1-specific OBD-I and OBD-II engine and tranny codes on his website, and P1680 is not included.

Yep positive. This is on my 04 Trailblazer. Here is where I found the code.

OK, everyone bookmark this page. It's the GM OBDII code decrypter. The 1680 code is listed.
