My daily commute is approximately 145 miles round trip of which is 95% highway. That being said my ‘19 RAM 2500 generated a “DEF system service” see dealer, to work and then about 1/2 way home it gave me the 150 mile countdown. At home tested injector, up/dn Nox sensors and all checked out good. Everything back together and started my truck up, message is gone. Drove all day yesterday still no message, any thoughts, shared experiences or suggestions?
