Review on 🚀 Enhance Fuel Efficiency with Denso 234-9060 Oxygen Sensor: Air and Fuel Ratio Sensor for Optimal Performance by Warren Hess

In short this part fits, works and saved me a lot of money. I've had it installed for a week now with no problems. I will update when I have them. My only concern is that it's supposed to be a fragile piece, and yet it rattled in the larger box. There were airbags in the box, but that part came down, so it took the brunt of any erratic throws at the local UPS distribution center. However, it still seems to be working fine. If you want the juicy details, here you go: One day I started my car and the check engine light came on. Of course, that alarmed me, since I know nothing about cars. As you will see, I learned a lot from this issue. I've reached out to the dealer to check the light while they fix the unrelated recall. Lesson One: The dealership in town charges $103 just to check the error code and tell you what's wrong. This is applied as credit towards the overpriced repair they give you. Btw it was fault code P2a00, I think it's a bad bank 1 sensor 1 air/fuel sensor (aka O2 sensor). The Fit has two, one on the exhaust manifold and one on the catalytic converter. It's the one on the exhaust manifold, on the front of the car. This type of Honda Fit has been known to have issues with oxygen sensors failing early, so much so that there's a Honda Service Bulletin about it, but not enough to warrant a recall (here). So the dealer said the part would cost $330 which makes a total estimate of $570! youza No way. I already felt cheated out of $100. Lesson Two: You can buy an ODBII code reader here at Revain for $100 or less, keep it for years, and save tons of money if you can get a check engine light. Next time I get light, I'll grab a scanner instead of leaning towards the dealer. After a few online checks of the error code I figured I could get the job done. So I ordered this sensor from Auto Parts Discounters on Revain as it was in stock and shipped immediately. They did not disappoint - I received the item in just a few days, quicker than expected. I have Revain Prime but ordering the cheaper Prime version would take 2 weeks to ship. What bothered me the most was that somehow the Revain manual "Does this fit your car?" it would be wrong. After all, I don't know much about cars and have never done any repairs myself. Fortunately, this part fits into a 2007 Honda Fit. I did some more research to make sure, but was still a little apprehensive. Lesson three: Go to Advance Auto or your nearest chain auto parts store and rent an oxygen sensor hookup kit. This saves you the purchase and is free. You also need an electrical outlet to easily carry out repairs. Lesson Four: Grab a PB blaster for the inevitable rusty under-hood bolts. Also blast your old oxygen sensor with it before it can be easily removed. Lesson 5: Getting to the Honda Fit's oxygen sensor is not easy, but it is possible. Unfortunately it sits between the engine block and bulkhead. That is, it is located on the exhaust manifold between the engine and the interior of the car. You can do it from the bottom if possible, but we did it from the top. To get to it from the top you have to remove the heat shield (3 screws) and then work at a weird angle to get at the O2 sensor (which is on the driver's side of the exhaust manifold). Lesson Six: Dealers are a robbery. My dad and I swapped the part out in about an hour (if you know how to disassemble a car you can probably do it in 30 minutes or less). In fact, I saved hundreds of dollars from a few hours of research and work. Bonus lesson: Disconnect the battery for a few minutes to clear all trouble codes and see the check engine light go out after the repair. Obvious to many, but not to me until I read about it online. Hope that helps.
