I troubleshoot the problem with my OBDII tool. Went to the local parts store, they wanted to much money in my opinion. Looked online found the same item for $50 less. Took a couple days to get here, same part works great so far. Comes with a one year warranty. Not sure how that would work on the return.

I bought this sensor to replace the bad one in our 2009 Toyota Sienna. This is the same one that you would buy from the Toyota dealership, only the price was about half of what it would cost at the dealer! I was concerned that the old sensor would be hard to remove. With a cold engine, I sprayed the threads of the old one with some penetrating oil, and the next morning, it came out with a very minimum of effort. When I installed the new one, I put a small amount of anti-sieze on the threads. Total job time: 20 minutes. Don’t take your car to the dealer and pay big money to replace this sensor when you can replace it yourself with a minimum effort. Save yourself $150, then treat yourself to dinner and a movie as a reward with the money you saved.

I get a check engine light on and the OBDII scan gave a code of P2238. The Car manual says the P2238 means “Oxygen (A/F) sensor pumping current circuit low (bank 1, sensor 1)”. It is obvious that the oxygen sensor will replaced. My friend offered me to help me to replace the Oxygen sensor and he said all you need to do is to buy a Denso Oxygen sensor and make sure it fit your car model. However, I am an extra careful person and do not want to take any risk. I know that dealer may charge me $400 for an oxygen sensor while I can get here for $100 and my friend can put it on for me for free, but I trust the big dealer. I bring the car to a Toyota dealer and would like the dealer to check and replace the Oxygen sensor. I leave the car with dealer (called AutoNation, Toyota South Austin, 4800 IH35 South). This is a very large dealer and used called Champion Toyota. A couple of hours late, the guy called me and say “okay, your oxygen sensor is okay, but the wire harness goes into the Oxygen sensor is bad. The replacement cost will be $932.82”. I am suspicious of that because the code says “Oxygen (A/F) sensor pumping current circuit low (bank 1, sensor 1)”, If the wire is broken, then it should be no current at all instead of low current. It should not be a wire harness problem. I asked him can you tell me what is the part cost and what is the labor for that $932.82? He said we do not give that details, we only give the total replacement cost. Then I told him that I will think about that to decide whether I will do it there or not and I paid him $68 diagnostic fee. He said “that’s fine but the wire harness can only be get through Toyota dealer, you cannot get from anywhere else and the cost is going to be the same”.
Then I did some research and try to understand what the heck the wire harness is. There are four wire connector for this oxygen sensor. One wire is the heating wire which should export a 12 V to heat the oxygen sensor. There are two signal wires, which should output a voltage of 0.2~4.3 V and the reference wire should have no voltage output. What I did was to unplug the oxygen sensor and use a multi-meter to measure the voltage from thatharness socket. The positive end of multi-meter goes to each of the four holes of the harness socket and the negative end of multi-meter goes to the negative end of the car battery. What I got was 12, 3.3, 2.9 and 0 Volts. That harness is perfectly fine! Then I emailed the dealer guy “what voltage he got from these four wire? Why he think the wire harness is not good?” but did not get his response
Based on that, I let my friend installed this Oxygen sensor I bought here, and surely enough, the check engine light now is off and we rescanned the car in Autozone, there is no any error code any more.

Worked perfectly for my 2009 Toyota Camry. The dealership wanted to charge me over $300 to replace this item. I had a shade tree mechanic install it for me for $15 about a month ago and I haven’t had any issues since.

So, My 2004 2.4L (4 cyl) camry had a p2238 code. My scanner tool stated 02 sensor Positive Current Circuit was low. Solution offered, to replace upstream sensor.
The toyota sensor is a Toyota brand number 89467-33080, which is nearly $200. after hours or research and online videos, the Denso 234-9010 was said to be the oem replacement for the toyota.
I replaced the sensor, the code went away, BUT the car now had hesitation and would not accelerate smoothly. after 15 miles of running a new code popped up. P0032 heater control circuit high on the this new sensor.
Some comments on amazon and even some online video comments had issues as well and even suggested a different sensor : Denso 234-9049 Air Fuel Sensor.
I Returned the Denso 234-9010 & bought this Denso 234-9049. WOW, what a difference. No codes, and car runs even better than the original that broke. Engine is smooth and strong. You cannot feel it or hear it when idle. Great sensor. Hope it lasts.

We have a 2008 Toyota RAV4 Limited with 3.5L V6 engine. Our vehicle has a little less than 100,000 Km on it. After our code reader showed P0051 Oxygen (A/F) Sensor Heater Control Circuit Low … I purchased this unit from Amazon. It matched the correct part number on the DENSO “find your part” website. Its an exact match of the factory part. The Toyota dealership wanted almost twice as much for the part.
I sprayed the base of the original unit twice with penetrating oil over a 2 day period and ran the engine for about two minutes to warm a bit before attempting removal (winter climate – working outside). Used a 7/8″ oxygen sensor removal socket, extension bar and a half inch breaker bar. A couple of sharp raps on the end of the breaker bar broke it free and I unscrewed it with my fingers. The threads remained intact.
Be sure to put the copper anti-seize, which they included, on the threads… but don’t get any on the sensor. I used a Q-Tip to apply.
Getting the electrical connector at the other end of the cable was more trying, especially in the cold. I slipped a very small slot screwdriver into the connector and gently pried it apart. Don’t break the connector.. as this would be a big hassle. Re-fit the cable keeping it away from hot surfaces.
Started car, cleared the codes with the code reader and the dash lights have never come back. Car runs great. Good luck with yours!

Was getting P0051 heated O2 sensor Bank 2 sensor 1 code for 2008 Toyota Sienna 3.5L LE and was triggering other i believe C1201 or something like that. However first i got only P0051 so figure it was the main culprit and read online that code would trigger other code due to interconnected system. I replace the original Toyota part number 89467-08050 Denso 1190 01K03 with this one (denso 234-9049) and all the lights Check Enginer, Track off, VSC lights went away. Spread PB Catalyst in the morning drove the van all day then in the evening spread again and was able to remove the old sensor in 5 minutes with TEKTON 4929 3/8-Inch Drive by 7/8-Inch Oxygen sensor socket. Make sure to apply copor anti seize that comes with the sensor. The sensor i changed is right in the front when you open the hood, it is called left-side (as if you are driving). Dealer was asking for $225 and was special order just for the parts and labor probably similar amount so saved about $400. These one is called air-fuel ratio sensor and has 4 wires. Hope this detail helps someone, and save $$$
I was sent a completely different color scheme compared to what was shown online. No good. Waste of time, I had to bring the package to ship back. –
Works just like it should, oem fit
