Mitsubishi B1079: Refrigerant Leaks
OVERVIEWWhat Does The Mitsubishi B1079 Code Mean?
DTC B1079 will be set when the A/C pressure sensor detects the refrigerant pressure of specified level or less.
Current trouble: The refrigerant amount is not at the specified level, or the wiring harness or connector between the A/C-ECU and A/C pressure sensor, and the A/C-ECU itself or A/C pressure sensor itself may be failed.
Past trouble: If DTC B1079 is stored as a past trouble, carry out diagnosis with particular emphasis on wiring and connector(s) between the A/C-ECU and the A/C pressure sensor. If the connectors and wiring are normal, and obviously the ECU is the cause of the trouble, replace the ECU. If in doubt, do not replace the ECU.
NOTE: When DTC B1079 is set, the A/C indicator of A/C control panel flashes.
What Are The Potential Causes Of The Mitsubishi B1079 Code?
- Malfunction of connector.
