Oxygen sensor malfunction has been experienced on the following vehicles:
^ 1982 and 1983 Camaros equipped with the 2.5L T.B.I. engine, Code 2.
^ 1983 Celebritys and Citations equipped with the 2.5L T.B.I. engine, Code R.
Code 13 is set, which indicates loss of oxygen sensor output, and results in open loop operation of the engine.
To correct this condition, an oxygen sensor with a new design, produced after January 1, 1983 should be installed.
A new part number has been assigned to the service package containing the new design sensor AFS-9P - P/N 5613959.
AFS-9P - P/N 5613725 or P/N 5613959 can be used for replacement on all engine applications specifying P/N 5613725.
