Saab is a Swedish automobile company that was acquired by General Motors Corporation in 1989 and by Spyker, a Dutch sports car company, in 2010. The first Saab production automobile, which came to market in 1949, was invented by the same engineers who designed Saab jet aircraft. Saabs made since the 1980s have computer controlled engines for efficiency and durability. The oxygen sensor in your Saab sends critical information to the engine control module. Replacement of a faulty oxygen sensor will get your Saab running smoothly again.
Open your Saab’s hood and permit the motor to cool down if the car has been run recently.
Locate the oxygen sensor, which is mounted in the exhaust manifold at the front center of the engine bay.
Spray penetrating fluid on the sensor fitting and allow it to work in for a few minutes.
Disconnect the wiring harness that comes from the sensor by pressing in on the tab and pulling the connectors apart by hand.
Remove the sensor from the exhaust manifold by twisting it out with an adjustable wrench in a counterclockwise direction. Match the old sensor up to the new one to make sure they are the exactly the same. Do not try to install an oxygen sensor that is not identical to the old one, as your car will most likely not run properly. Discard the old sensor.
Twist the new oxygen sensor into the threaded hole in the exhaust manifold and tighten it in a clockwise direction with a torque wrench to 30 foot-pounds.
Push the wiring connector of the sensor back into the wiring harness until it clicks into place. Close the hood.
