Will a P0191 DTC on a 2003 Ford Taurus SES affect the transmission shifting? Lost the ability to shift auto transmission and received this code when I ran a scan. No problems with trans up to this time.
P0191 is related to the engine could be caused by an intake leak or fuel pressure related.
if the engine is in fail safe mode, it can affect shifting on the transmission
check for intake leaks and fuel pressure first
see specs below
