Installing heat sensor - Kenmore km 911 9368310 324686 Thermostat Control, Oven Range

did you install a O2 sensor or a heated O2 sensor
they are different items and do different jobs
The heated oxygen sensor (HO2S) reads the exhaust gas composition and reports to the ECM to adjust the air /fuel mixture to obtain maximum economy and performance
It is found in the exhaust manifold or before the cat converter
the oxygen sensor (O2 ) is found after the cat converter and reports on the cat converter operation
after installing the correct sensor use a scan tool to reset the ECM

Removal & Installation

Raise and support the vehicle.
Support rear of the powertrain frame.
Remove four rear frame bolts.
Lower the frame no more than 73.2 mm (3 inches).
Disconnect the rear oxygen sensor electrical connector.
Remove the rear oxygen sensor from the rear exhaust manifold.

To install:

Install the rear oxygen sensor in the rear exhaust manifold. Tighten the rear heated oxygen sensor (HO2S) sensor to 41 Nm (30 ft. lbs.).
Connect the rear oxygen sensor connector.
Raise the frame.
Install the four rear frame bolts. Tighten the frame bolts to 100 Nm (74 ft. lbs.).
Lower the vehicle.


Heated Oxygen Sensor Bank 1 Sensor 1 (HO2S 1/1)

WARNING: Handle the oxygen sensors carefully in order to prevent damage to the component. Keep the electrical connector and the exhaust inlet end free of contaminants. Do not use cleaning solvents on the sensor. Do not drop or mishandle the sensor.

CAUTION: Remove oxygen sensors with the engine temperature above 48C (120F). Otherwise the oxygen sensors may be difficult to remove.

A special anti-seize compound is used on the oxygen sensor threads. New service sensors should already have the compound applied to the threads. Coat the threads of a reused sensor with anti-seize compound P/N 5613695 or equivalent.

Hi:
The Number 1 Heated Oxygen sensor is located in front of the catalytic converter. You would need to get the car up in the air, and then disconnect the electrical connector, and possibly need a special socket to remove the sensor. Also remember to purchase and use Oxygen sensor safe anti sieze compound on the threads of the new sensor, if you do this your self

you need to borrow the oxygen sensor wrench from autozone or whereever you bought the sensor.
