Hello and welcome to JustAnswer!

This code could be caused by an issue with the heater control circuit wire, the sensor itself, or a loss of ground to the heater. Wiring issues are possible but oxygen sensor codes are most often set by failed sensors.

Bosch sensors are all but guaranteed to set heater codes on any Chrysler product with an NGC powertrain control module, and they're unreliable in general. Does your powertrain control module have three connectors or four?
