How do you remove an oxygen sensor from a spark plug?
Remove the sensor, and take to your local car parts store. Find the part called a spark plug defouler. The threads on your spark plugs match the threads on your oxygen sensors, thus the sensor will be able to thread into the back of the defouler. Buy 2. Measure the diameter of the tip portion of the oxygen sensor that extends past the threads.
What can cause an O2 sensor to set a different code?
There are also some other possibilities such as an internally leaking EGR system. This will typically set a separate code. A leak in the exhaust system before the (O2) sensor will also cause incorrect readings. The only other possibilities are wiring issues, and computer concerns.
Can a bad O2 sensor cause a bad catalytic converter?
Bad o2 sensors, clogged catalytic converters and a host of other failures can cause those symptoms. It’s hard to tell without codes being set. If you have access to a diagnostics scanner that reads live data, watch the o2 upstream data as well as the downstream o2 data.
Can a faulty oxygen sensor be replaced on a Honda Civic?
