anyone know what code P1693 means
Simple!

There is 2 computers on these trucks ECM (Engine Control Module) and PCM (Powertrain Control Module). When one or both modules get a error it will put a P1693 in the opposite controller to notify you that the other module has a problem.

So basically all it means is that either one or both modules have error codes...:w:

Yes sir... It does... The PCM controls several other sub systems like your gauge cluster, torque management (1st and 2nd gear on a manual trans), etc... It mounted on the firewall behind the air filter box on the passenger side...:w:

There is a bunch of conditions the computer must follow to shut off the CEL or erase error codes... The rest of the information is here...
