Code 0032
NOTE: Codes 0031 and 0032 may have been
mistakenly activated by turning key ON with
oxygen sensor disconnected. If either code
status is historic, that code may have set during
assembly or a previous repair and may not be
related to current event. Clear codes and retest
to confi rm. If code status is current, refer to
Oxygen Sensor (O2) earlier in this section, to
test and troubleshoot.
