How did you bypass the O2 sensor and clear the error code?

UPDATE!
The thermostat.
Of course, the thermostat was gone. Our kazeems no de waste time to yank it out. And her fan was on all the time. So I went to my parts dealer and requested for a thermostat. My dealer and everyone around were looking at me like I'm crazy. But I didn't care. I insisted he sells one to me and he eventually did. Note that the thermostat comes together with the housing and is not supposed to be separable. I was offered the whole housing with the thermostat but cheap me refused. How will I buy the whole thermostat housing when my own housing is intact. So cheap me collected a thermostat removed from another car. I went home, tested it inside hot water to confirm it works well while checking the temperature with my thermometer. Then, I coupled it back to the housing (this was not easy but it has to be done as cheap as possible ). After installation, car was happy but...
The fan was still on permanently.
A code was on about the ECT sensor. So I traced the ECT sensor and noticed the wire was dangling behind the radiator. I located the ECT sensor and tried to plug the connector back, but for some reason, the plug couldn't enter. I was able to look at the sensor on the radiator and realized the socket and the plug are completely different. Omo! I begin to scratch my head. What is going on? A few pages of googling, I got to learn that 2003 - 04 accord use different radiator from 2005. The only difference actually is that 2003 04 use "fan switch" while Honda switched to Engine Coolant Temperature (ECT) sensor from 2005.
The fan switch (03 and 04) just switches on the radiator fan when the coolant is hot enough (off and on switch), while the ECT sensor senses the temperature of the coolant and sends the information to the brain box. The brain box uses the information to know when to switch on and off the radiator fan.
Note that these two items, fan switch and ECT sensor, are completely different in both size and function. One can not replace the other. This in turn makes the radiator for 03-04 not compatible with 05. You can not simply remove the fan switch and replace it with ECT sensor, cos the thread size is not the same. ECT sensor is smaller. I learnt this after buying an ECT sensor to install but couldn't fit it into the hole as it was smaller.
For all of you using this car, if you want to replace your radiator, make sure you are buying the correct one for your car
Some kazeem, in his infinite wisdom, installed a radiator for 03-04 on my 05 accord. And because the connector doesn't fit, he just left it dangling and made the fan permanent.
Since the only difference is the the thread hole, I can't just throw away a fully functional radiator just because of thread size. So I found a thread reducer. This wasn't easy as I couldn't find the perfect reducer that can convert the 18 thread of the fan switch to the 12 thread of the ECT sensor. I had to order something close from AliExpress and gave it to a metal works guy to make it work. Eventually, my ECT fit into the hole and no leaks. But the fan was still permanently on. A little rummaging in the under hood fuse box revealed the problem. The fan relay was bridged. Removing this bridge and everything worked according to design. Finally! Praise God!
The whole higihaga above took me more than a month to figure all out and find solution to all. But it was fun.

The moonroof was even more challenging.
I started by adding more lubrication to the rails and cable but that didn't help. My kazeem noticed the moonroof motor gets hot and said the motor needs to be replaced. I strongly doubted this cos I know that the only reason a motor gets hot is if there's resistance to its movement. So I suspected that it was the stuck moonroof that is making the motor work too hard and therefore gets hot. But since I was out of ideas, I decided to go with it. But of course, two motors later and same issue persisted. I also noticed a lot of maneuver has been done to the moonroof in the past. The rail even has an injury at a point like something hit it. So I was already giving up on the moonroof when I stumbled on a car being parted out. The moonroof seemed intact and the owner told me to bring 10k and take the whole moonroof assembly. That is because nigerians don't give much f++k about moonroof. Omo! Na speed I use collect am o.
But ironically, after installation, the moonroof still refused to move properly
After a lot of head scratches, the body work guy that helped me install it gave me the usual kazeem talk "just start using it like that, it will free up with time". But I knew that was bullshit. So when I got home, my brain just couldn't rest. So I went back on my own to bring down the roof liner and removed the moonroof assembly. This was the most difficult task I've ever tried on my own. Omo! I sweat die sotee I asked myself "who send you". But after reinstalling it same problem continued. The holy spirit then whispered to me to try something.
I removed the motor, pushed the moonroof glass all the way back, made sure the two sides of the glass hit a stopper, then I reinstalled the motor and voila! That was it. The glass closed and open very smoothly. I felt like I won the world cup. It happened that the kazeem body work dude, while removing the moonroof assembly from the other car, removed the motor and moved the glass. This put the glass and it's cables out of alignment, therefore increasing resistance. I even returned all the new moonroof motors I bought and reused the only one in the car.

So finally all is done. Little money, but plenty stress.
Betty was now happy. Engine has not overheated till today. Moonroof still works smoothly till today.

And did I mention I gave Betty a factory booth spoiler? Yes I did and she was happy. I love spoilers.

Recently, the devil decided to tempt Betty. A heavy wind blew on the 14th of this month. This evil wind uprooted a solar panel from somewhere I don't know, carried it all the way, and landed it on Betty. Betty's front passenger window shattered, the side mirror was destroyed, and the door was injured seriously. I cried for Betty that day because she didn't deserve that. Betty is still recovering.
I'm using the opportunity to give her the TSX side mirrors I've always wanted. After that, I'll repaint her.
