The 02 sensors are in the exhaust pipes but don't know about the updraft sensors.
It has 4 oxygen sensors 2 before the cat. and 2 after the cat. $ 50.00 each at Auto Zone.
where are the oxygen sensors on a 2000 Pontiac grand am and how do you change them?
Why?
If your 2000 Ford Expedition is throwing a code 1132, then you should first try to change the oxygen sensors. If that does not remove the code, a mechanic will need to determine the exact cause.
I believe there are 2 oxygen sensors that are used for air / fuel ratio and 2 oxygen sensors that are downstream from the catalytic converters and are called catalyst monitors
On my 1998 Ford Expedition XLT , There are 4 Oxygen sensors. 1 each in front of the Cats. and 1 each behing the cat. for a total of 4 Oxygen Sensors.
use a 7/8 ring socket or line wrench or if all eles fails use a 7/8 snap on wrench
ONLY when they go bad. Not untill.
The oxygen sensors on a 1998 Chevrolet S10 are changed by disconnecting the lead wire and unscrewing them from the exhaust manifold. New sensors are then screwed into place and the wires reattached.
Those are the oxygen sensors in the exhaust above the catalytic converters.
Usually oxygen sensors are what would be screwed into the exhaust manifold.Usually oxygen sensors are what would be screwed into the exhaust manifold.
oxygen sensors are part of the exhaust system
