I don't think it's important which is which as long as they are downstream. There is a slight difference in their function. I have included the dense part numbers below. In the Upstream Including the valve positioned in the exhaust manifold is 40224*Deep down in the exhaust system A catalytic converter is the first piece of hardware installed after the first one (4623 )
In general, the following is true in terms of the flow of air from the engine through the exhaust system. In this example, Sensor 1 is before the catalytic converter (Upstream O2 sensor) and Sensor 2 is after the catalytic converter (Downstream O2 sensor) *br> *br>I hope you found this information
You can, but it won't last.
It is not necessary to have a California emission part number to order an In order to determine your O2 part number, you need to have your car's VIN

It may not be a mechanic's story, but this is my experience. Check engine light (CEL) went on in my car. The Toyota technician stated that the bank I catalyst efficiency was below threshold over a predetermined period of time because of a P0420 code. According to them, $2263 is the quote. The cost of repair is 74 dollars. A CEL appeared and disappeared for a long period of time. At an Autozone (which, if you didn't know, checks the engine light for free) I was able to confirm the code. This product was available on Amazon and I purchased it with the idea that I had nothing to lose. I drove the car for a week without experiencing any problems after replacing the light. It has just been a few days since I passed emissions, so I am writing this review! I have some tips for you regarding how you can accomplish this Please, all-- You can find out where this sensor is located by watching a YouTube video. There is one on the right side of the car, just after the exhaust pipe starts to run horizontally
- Make sure the exhaust is hot when applied so that the oil can penetrate the connections. Let the connection sit for at least 30 minutes before remounting. Please note
A 7/8-inch wrench can be used to remove the plug - Using the fingernail and a paper towel, carefully remove part of the carpet from the footwell of the front passenger. Continue peeling along the center console and across the back firewall until the plug is attainable under the radio in the middle of the car, still on the passenger side. The wiring connection is held in a clip retainer and slides out when the car is pushed rearward. Wires need to be fed through the floor of the car once the car is disconnected. You will need to push out the rubber seal that holds the wire in place. Put the new plug in place using the ring that came with the kit, then apply the anti-corrosion compound Make sure not to apply anti-seize compound to the holes of the sensor but to the threads. Please note
I cut off and reused the old seal that came with the kit, as well as the metal wire retaining clip from the original, because the seal that came with the kit did not fit in the floor like the original for me. Please note
Connect the cable to the center console and secure it into the The carpet needs to be replaced. Please note
You should periodically consider what you will do with the remaining money you saved while you drive. You're going to have a lot of fun Thanks for reading this, I hope it was.
Some time has passed since our last meeting I needed to replace a oxygen sensor on my 2007 Toyota Prius due to a hole cut in the catalytic converter. The temptation to buy an aftermarket 02 sensor for $35 less was too great for me to resist. I had no problems installing this Denso 02 sensor and the device works well. In contrast to the Chinese 02 sensor that I had to replace within a couple of months, I have no worries about having to do so again in a An important point is that the 02 sensor on a second generation Prius connects to the car's computer through a hole in the floor in the upper-mid compartment of the car A view of the front passenger footwell from the left. The floormat must be removed from the passenger seat before you can get to it, pull up the carpeting in the upper-dash area The footwell of the passenger is at the left corner. It was possible to do this without removing the plastic trim pieces (although one of the clips holding the carpet in place on the inside broke/pulled out, which is no big deal). Despite the one missing carpet pin, I was able to press/wedge the carpet back under the plastic trim. The carpet looks excellent and everything is as solid as before.
This is what I purchased and used I replaced the downstream O2 sensors (Denso 234) on my 2002 Toyota Celica GT with these parts The Oxygen Sensor (4623) & A sensor (Denso 234-03) is located upstream The Oxygen Sensor 4604 is used in this application. The Denso Group manufactures automobiles and industrial equipment for Toyota & Honda O2 sensors come with connectors so that you can just plug them into your car without having to splice anything at all. I was experiencing the P0420 Catalyst System Efficiency Below Threshold error code until I fixed it. Taking a look online, you will find a lot of ideas, claims, and claims that are contradictory You'll find products that promise to resolve the problem at an affordable price. In my opinion, my car is 18 years old, so I would rather do a repair for the parts that may have been the problem & just replace them instead of replacing the whole thing. It is hoped that you will be able to drive another 18 years without encountering P0420 errors. Those who purchase an 02 sensor wrench should also pick up one By using the wrench, it will be that much easier to remove the old sensors & controls To tighten new sensors without damaging them, make sure they are not damaged. Spray the bolts & nuts with paint as well If you intend to remove the sensors in the future, I suggest you use a penetrating oil to help dissolve/break the rust. You could also use some antiseize on the threads just in case you need to take them out. You can install an Eastern 40618 Direct Fit Catalytic Converter in your 2002 Toyota Celica GT if you need a catalytic converter. The above review is intended to be helpful, but I hope it also.
Thankfully, I did not see any error codes with it, and everything worked like a charm. A downstream sensor such as this for the Prius is easily accessible on both ends, and it is comfortable to use Simply screwed into the exhaust pipe, the sensor connects to the connector in the cabin beneath the carpet and center console in front of the passenger. The two pieces don't need to be removed completely, just pulled out of the way enough to pull them apart and reconnect them. It even comes with a new rubber fitting that simply presses into the hole in the floorboard and is very.
The same part is available from Toyota at half the price through Denso, the car maker's supplier. For '06 prius, you have to pull back a small piece of carpet on the front passenger side to access the hole to connect to the tail pipe. It sounds more difficult than it is, but it's easy to do.
I went to a few websites to compare prices for new oxygen sensors I needed for my 2001 Toyota Prius. My manufacturer used these, and they were the best price and kept the OEM look and feel of the car. This seemed to help with engine light issues I was having with my little car. This is a great product to recommend to people who need to change these little guys, which last around 120K miles on average. You don't have to worry about rusting in your oxygen sensor area with these since liquid copper prevents corrosion. When you come back around to changing your oxygen sensors, they will be easy to remove. purchased both the upper and lower parts to replace mine, and I was pleased with their quality. The product is also made in the U. S. , so the value is higher. Making purchasing decisions based on reviews from the Amazon community is one of the reasons why I have been a customer for years. Having said that, I believe in only giving honest and unbiased feedback. You are welcome! Thank you so much.
