Chrysler/Jeep/Fiat Oxygen Sensor 55243216 0258010331 Plug and Play No Programming Needed

When your Chrysler, Jeep, or Fiat experiences check engine light, increased fuel consumption, rough idle, or weak acceleration, this usually indicates the original oxygen sensor has aged or failed. The sensor feeds back the air-fuel ratio signal to the ECU to help control injection precisely for optimal combustion and emissions. OEM number 55243216 (also compatible with 0258010331) for Chrysler, Jeep, and Fiat standard models. Direct plug-and-play replacement with no programming required, but ensure sensor connector and harness are firmly connected to avoid poor signal.
