|Oxygen sensor location|
|O2 Sensor removal tool|
I have to admit, this entire thing made me nervous. Every time I attempt something that has never been done before ( by Me) on the Subaru, I feel a little apprehension. I lack the tools and confidence... mostly the tools, to take on projects that are tough or complicated. If a bolt breaks, or a part is frozen into place, I'm sunk.... and so is Subie.
|I'm not sure what bad looks like, but this might be it.|
|Compare. Which one looks better?|
|Old plug left all the "white parts" inside the female Plug.|
But, Surprisingly! it all worked out. I managed to prop up the car without squashing myself, I removed the tire and was able to access the front 02 sensor and break it free. Easy!
|New O2 sensor installed.|
The slight hiccup happened when the plug would not fit. After several choice words, a minor fit, a sudden downpour of rain, and a grain of sand in my eye, I finally figured out that the "guts" of the last plug were stuck inside the female end, preventing the new plug from seating properly. One needle nose pliers surgery later and I was back in business.
|Time for the back O2 sensor.|
|Slightly different. No problem?|
Then there was the rear O2 sensor. Slightly more challenging to get it loose, but I managed it. I was a little concerned that the actual parts did not match up identically, But the NAPA guys says that should not matter. ( we shall see about that.)
|At least the "Pig Tails" match.|
|No "Check Engine" light!|
In celebration, we head out for a victory Sundae. And half way to Kalona, the Check engine light returns.
|It's Back! Like a bad rash.... but at least Subie Runs better.|
