Yes
Yes it does cut your car off, The sensor is controlled by module that controls everything
No it will not.
if a knock gos bad can your car go off
IMPORTANT: DO NOT DROP THE OXYGEN SENSOR. EXTREMELY FRAGILE!!!! First figure out which one to replace. Buy a sensor for your model car or a univeral one. Should require four wires. Use a slotted socket or a wrench to remove the old sensor. Cut the wires approximately 3 inches from the connector between the connector and the old sensor. Wire in new sensor and install. Further instructions should come with sensor.
In the exhaust pipe. the oxygen sensor is not in the exhaust pipe it is directly under the hood off of the exhaust manifold. it sets by itself and is easy to get to. you will probably have to cut the old sensor wire to get the old one out.
Saab used heated oxygen sensors on this year car. There is a heated Bosch Universal sensor that will fit; you cut the plug off your old one and wire it to the new sensor. If you mean "how can I replace the sensor on my car with the $15 version that doesn't have a heater on it?"...unless you really like check-engine lights you can't. The car's computer will notice the sensor isn't talking to the heater circuit, assume the sensor's burned out, and start throwing codes all over the place.
Maybe intermittent ignition. But more than likely it's a sensor. Possibly an o2 sensor. I've also heard of the EGR doing this too.
let vehicle run to get exhaust hot, spray penatrating oil where threads are..... wait..... yes oil is flamable, so be careful.. try it. no luck? cut wire or wires and put a 7/8 or 22mm socket on sensor
It requires a special socket with one side cut out so as not to damage the wiring.
YA!
No, but it could effect how the transmission shifts.
Cut the wire, unscrew the old oxygen sensor then replace it with the new one and finally, connect the new wire, making certain that you follow the manufacturers wiring diagram. To find the oxygen sensor, look at the exhaust manifold, then follow it down to where the manifold feeds into the headpipe. The oxygen sensor is the part that screws into the exhaust and has a wire connected to it.
