Thank you for that information.
There are two main onboard computers on your truck; the ECM that controls how the Cummins runs and performs and the PCM that controls other systems such as charging, starting, HVAC, transmission, etc.
P0237 sets when the ECM detects MAP sensor signal voltage dropping below 0.1 volts for 2 seconds with the engine running.
P1693 sets when the PCM detects a code has been set by the ECM - once the reason for the ECM code is fixed, this P1693 will go away.
Now, I'm a retired Chrysler/Dodge/Plymouth Master Technician and, as such, am familiar with how these engines run. However, I'm not an expert on aftermarket accessories such as this Bully Dog Power Pup, nor I know how it is wired onto the the existing harness, or its effects on the existing ECM parameters. This means I would need your help in finding more information about it; things like installation instructions, wiring diagrams and performance specifications. Optionally, I could opt out and re-open the question to the field so you could then wait for another expert to respond. How would you like to proceed?
