Good morning! About 200 miles into a 500 mile road trip yesterday my wrench light came on in my 2017 Explorer with the 3.5 naturally aspirated engine. When it happened I was doing about 88 mph and did not notice any driveability issues. While exiting the highway to get fuel it felt like a slight misfire. Restarted the car after fueling and the light has not reappeared. I did notice one slight misfire late last night, but nothing else.
Unfortunately I didn't bring my OBDII dangle so I can't scan with forscan and Autozone couldn't pull any codes. Has anyone ever experienced this sort of thing? I did an oil change in it the day before and used Motorcraft oil and filter. I am wondering if maybe I justvgot some bad fuel to start the trip.
Thanks in advance for any help! I just want to give my wife peace of mind that we'll make it home lol.
nearly month later...did the light come back? What did Forscan tell you assuming you made it home.
Forscan had some codes for the transmission temperature sensor. I was able to diagnose and determined that the solenoid pack needed to help replaced. I replaced the part and programmed it through Forscan. So far no issues, but it has only been on site trips since then. I will be taking it over the road in a few weeks, so that will be the real test.
