U110E: Lost Ambient Temperature Message
2 vehicles · 2 makes · $700-$1,200 repair
Most Reported On
U110E is an OBD-II diagnostic trouble code meaning “Lost Ambient Temperature Message.” A Chrysler/Dodge/Jeep/Ram network communication code. The ambient air temperature sensor is a direct input to the body control module, which then broadcasts the outside-temperature value over the CAN C bus to the PCM and other modules; this code sets when the receiving module stops getting that message. Typical symptoms are an outside temperature display stuck at -40 or dashes, no compass/temperature readout, and sometimes odd HVAC or automatic climate behavior. Engine performance is usually unaffected, and this is a message/communication fault rather than proof that any single sensor is bad. This code is most commonly reported on 2008-2014 Dodge Challenger (SE, SXT, R/T, SRT8, Rallye), and 2018-2024 Jeep Wrangler (Sport, Sahara, Rubicon, 4xe), with repair costs ranging from $700 to $1,200.
