Subject:
OXYGEN SENSOR SETTING CODE 13 - 1982-1983 FIREBIRD AND J2000 MODELS AND 1983 6000 AND PHOENIX M
This bulletin supersedes bulletin 83-T-19 and should replace it in your file.
Oxygen sensor malfunctions have been experienced with some 1982 and 1983 Firebird, J2000, 6000, and Phoenix models equipped with the 1.8L and
2.5L EFI engines. A Code 13 is set when there is a loss of oxygen sensor output, which results in an open loop operation of the EFI system.
To correct this condition, a newly designed oxygen sensor produced after January 1, 1983, should be installed. The part number for the new sensor is
5613959. The new sensor should be used whenever replacement becomes necessary.
For all other applications, either 5613725 or 5613959 may be used.
