Endeavor V6-3.8L SOHC (2004)
Standard value:
CAUTION:
-
Be very careful when connecting the jumper wire; incorrect connection can damage the heated oxygen sensor.
-
Be careful the heater is broken when voltage of beyond 8 volts is applied to the heated oxygen sensor heater.
NOTE: If the sufficiently high temperature [of approximate 400 °C (752 °F) or more] is not reached although the heated oxygen sensor is
normal, the output voltage would be possibly low although the rich air/fuel ratio. Therefore, if the output voltage is low, use jumper wires to
connect the terminal No. 1 (red clip) and the terminal No. 3 (blue clip) of the heated oxygen sensor with a (+) terminal and (-) terminal of 8 volts
power supply respectively, then check again.
3. If the output voltage is not within the standard value, replace the heated oxygen sensor.
NOTE: For removal and installation of the heated oxygen sensor, refer to Exhaust Pipe and Main Muffler.
