    Default p0191

    Have a customers vehicle that is setting a P0191. Rail pressure sensor has been replaced, ran injector return rates and all checked out. Rail overflow valve also new. Looks like Dodge has updated software 2 times for same code. No way to modify parameters to stop diagnostics from running?

    Then you might look into finding the most current calibration for that vehicle and flashing it in
