OXYGEN SENSOR
OXYGEN SENSOR INFORMATION
• The oxygen sensor, located on the exhaust pipe
before the muffler, uses a 4 wire heated element.
First, verify if there are any stored codes for the oxygen
sensor.
NOTICE
The ECU must first run though the O2 sensor time
delay before a trouble code will be set. This may take
several minutes at idle to occur.
Short drive cycles and cold temperatures will both affect
the delay time of the O2 sensor (increases the delay).
The delay time ensures the oxygen sensor heater has
run long enough to provide accurate data.
