There are several reasons why the OBDII error code U016A may be triggered. Some of the most common causes include:

  • GPS antenna or module failure
  • Wiring or connector issues between the GPS module and the PCM
  • Software or firmware issues with the GPS module or PCM
  • Physical obstruction or interference with the GPS signal
  • Low battery voltage or electrical system faults

Possible Fixes for Error U016A

To resolve the OBDII error code U016A, it is essential to identify and address the underlying cause. Here are some possible fixes:

  • Inspect and replace the GPS antenna or module if necessary
  • Check and repair any wiring or connector issues between the GPS module and the PCM
