How do you check a catalytic converter with a vacuum gauge?
To diagnose a plugged catalytic converter, you can check intake vacuum or exhaust backpressure. To check intake vacuum, connect a vacuum gauge to a vacuum port on the intake manifold. Start the engine and note the vacuum reading at idle. Then increase engine speed to about 2,500 rpm and hold steady.
Where is the O2 sensor on a Honda Prelude?
An oxygen sensor measures the unburned oxygen in the exhaust as it exits the engine. The Honda Prelude o2 sensor location is in the exhaust manifold. The reason for the measure is to gauge the fuel mixture and see if it is burning rich or lean.
Why is my Honda oxygen sensor not working?
Test your Bosch oxygen sensors if you’ve been using leaded gasoline, have a problem with coolant leaks or frequently add oil to your car. A Honda oxygen sensor may fail if it becomes contaminated by silicone (from gasket sealers), phosphorus or lead.
Where is the O2 sensor in a car?
The o2 sensor (oxygen sensor) is located within the exhaust system, upstream of the catalytic converter. Its role is to inform the ECU of the oxygen content of the burned gases that result from combustion. The o2 sensor helps to ensure that the amount of fuel injected into the cylinders for the air-fuel ratio is at an ideal level.
What happens if the O2 sensor fails to function?
Finally, if your (O2) sensor fails to function properly; your engine management computer cannot determine the air to fuel ratio. Therefore, the engine is forced to guess how much fuel to use. Resulting, in a polluted engine and a poorly functioning vehicle. It’s true that many of these symptoms could be caused by various problems.

What causes bad engine lights and O2 sensor codes?
There are other possibilities besides bad sensors that will set these kinds of trouble codes. Major and minor problems with the engine or vehicle could be at the root cause of the malfunction.
What does O2 sensor code 08-s-05 mean?
The Ford recall number is 08-S-05. Another thing I would like people to understand is the O2 sensor code does not mean it’s time to replace the sensor. It means that it’s time for some diagnosis and repair. If the diagnosis leads to a replacement of an oxygen sensor that is just fine.
Can a vacuum leak cause an oxygen sensor to fail?
Unfortunately for the ruined oxygen sensor the vacuum leak was so severe that the power train control module could not compensate. As mentioned above vacuum leaks can cause an extremely high combustion chamber temperature and post-combustion chamber temperatures as well.
