O2 Sensor symptoms
This morning, my check engine light came on for the first time in the 4 years I have owned my 2004 EX-L 4 cyl Sedan.
I was able to make an appointment at the dealership for Tuesday PM (in 4 days).
From what I can see here, the most likely culprit is the O2 sensor.
Lately I have found my car to use a little more fuel than usual, although it's not that obvious. Also, on colder mornings, I find its exhaust smells funny. It's a strong smell. It almost smells like unburned fuel and I smell from pretty far away from the car. However, I have been noticing that from quite some time, well before the light came on.
Could it confirm that it's the O2 sensor that has been degarding over time or is the sensor one of those parts that either works or not ?
Also, I know how everyone feels about stealerships... It sounds like this is a no brainer but frankly, working on my car is not my cup of tea. Having said that, is this something simple enough for any garage to diagnose and fix ?
