Check engine light came on in traffic. Truck still runs fine, gas mileage is the same, oil pressure is okay, temp is okay, all fluids are okay. No loss of power, idle is normal.
Disconnected battery to reset light and it stayed off for about 100 miles.
Is there something pre-programmed in that would set the light off at or around 54k miles?
Anyone have any ideas?
Thanks in advance
