Question

I got the codes U0155 and U110C on a 2005 Dodge Caravan 2.4L, what is the meaning of the codes?

Answer 1

The Powertrain Control Module (PCM) continuously monitors the fuel level from the Fuel Level Sensor through the Body Control Module (BCM). The U110C code indicates that the PCM lost fuel level communication from the BCM. Start by checking the PCM and BCM harness connectors, retighten the connectors, and clear the code. Also, check the battery charge, as a low battery charge has been reported to trigger this code. If the problem persists, replacing the BCM will be necessary to repair the issue.
