A DTC that indicates a low oil temperature warning on a 2015 Jeep Wrangler may just need a software update.

This bulletin applies to 2015 Jeep Wrangler vehicles equipped with a 3.6L engine and 6-speed manual transmission. The MIL may be on with DTC P1239 (engine oil temperature too low.)

Also, there may be a perceived misfire under normal acceleration and the starter protection feature may be disabled. Reprogram the PCM with the latest available software.
