Hi I've a 2015 ecodiesel today just like 2 hours ago the engine light came on,I went to the AutoZone for they to plug the code receiver and show up this code P0191 gir Fuel rail sensor said so I need help to see how to fix and where is located this sensor thanks group
Today I started and notice that I've an engine light on and says on the messages that DEF service see dealer. Also my A/C stop to blow cold air i guess that the A/C issue was a cause for the ambient temp sensor but also the DEF light too?? What are you guys think, thanks
