Re: 2003 Dodge Ram 2500 5.9L Cummins Diesel I got that from the code page.
quote:Could be that the batteries popping like they did burnt a few wires.
What does that mean?
P0209 means that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled "low" or close to zero. When the injector is switched off, the PCM expects to see a voltage that is close to battery voltage or "high". If it doesn't see the expected voltage the PCM will set this code. The PCM also monitors resitance in the circuit. If the resistance is excessively low or high it will set this code.
The symptoms for this code will likely be a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated.
code quote, you'll have to scroll to see the code.
