A New Oxygen Sensor Impacts Your Car!


A defective or sluggish oxygen sensor can cause a variety of issues, like decreased engine performance. Replacing a defective O2 sensor helps ensure your engine is constantly monitored and operating efficiently, while maximizing performance.	The ideal air-fuel ratio of a gasoline engine is 14.7 parts air to 1 part fuel, which is known as complete combustion. The vehicle's engine control unit uses an O2 sensor to regulate air-fuel mixture by checking the oxygen content in a vehicle’s exhaust. This results in fuel savings.	The catalytic converter is responsible for removing the harmful emissions from your vehicle’s exhaust. A defective oxygen sensor can cause your catalytic converter to fail prematurely. Replacing a catalytic converter can cost thousands of dollars, significantly more than most standard oxygen sensor replacements.	If complete combustion is not maintained, other chemical compounds can form in large amounts. These include greenhouse gases, carbon monoxide and excess hydrocarbons. Replacing a defective oxygen sensor is the most effective way to control the combustion process and reduce emissions.

Upstream O2 - 2011 Kia Soul 2.0

Reviewed in the United States on January 17, 2020

Verified Purchase

No retailer had the upstream o2 sensor for my 2011 Kia Soul 2.0. I ordered this universal Bosch, splicing the wires was super easy! The instructions were a bit hilarious, felt like I was a child but they were quite effective! If the attached instructions are too complicated for you, you're best off purchasing the direct fit (no wire splicing involved) or taking your vehicle to a professional. I will update if I run into issues specifically linked to the o2 sensor.

Great for my Scion xA

Reviewed in the United States on June 22, 2011

Verified Purchase

My 2005 Scion xA was giving showing the check engine light, which a scan revealed was a problem with the downstream oxygen sensor. This universal sensor is considerably cheaper than the OEM-connector sensor and well worth the little bit of extra work. The instructions make it pretty hard to screw up. I used a 7/8 inch box wrench, and used a hammer on the wrench to knock it loose. Then I followed the instructions to wire up the connector. The connection seems very solid, but I was able to run enough wire to locate the connector box inside the car just for extra protection. I would still be confident in it sitting underneath the car. After I plugged it in, the car started like normal and the check engine light was off. Excellent value from a well-known company like Bosch!

I ordered this Bosh 02 Sensor from Amazon, Passed Smog Test, and Saved 70% !

Reviewed in the United States on June 27, 2013

Verified Purchase

My 2005 Mercedes 230C failed smog inspection for the first time by .01% (the lowest fail percentage). Although the car ran fine, the "Check Engine" light had been on for a few months.

After checking online for the "Fail Codes" listed on the Smog Test receipt, the codes pointed to the "Downstream o2 Sensor (Oxygen Sensor)" making the fuel mixture too rich. So I called a local Smog Repair shop and I was qouted $220 dollars to replace the part. My former brother in law who had his own auto repair shop told me long ago that mechanics get a 50% discount off list price of new parts, but always put the list price on your bill. So I ordered the part from Amazon, and had my local independent mechanic install it. I saved 70% from the original smog repair quote by doing it this way.

This Bosch 15733 Oxygen Sensor came in Bosh box and with a Universal Connector plus Wiring Instructions. I think any weekend mechanic could handle the job within a few hours but.... I am getting too old to climb under a car anymore. The replacement requires Auto Lifts, a standard Open End Wrench, and Wire Crimping Tool. In my case the Universal Connector supplied Did Not Match the one on my car, so splicing the 4 wires to the original factory connector was required. The 4 wires consist of 2 signal and 2 grounds, and had the same color codes as my original wires. Once removed, the O2 Sensor appeared to have a small amount Black Soot around the base of part as a result of running too rich. After installation the "Check Engine" light went off.

The one thing that I havn't seen in the Amazon Reviews is that my mechanic had to Re-Set the Car Computer. He also told me I had to drive 60 Miles More so that the car computer could re-evaluate the "New o2 Sensor" in full cycle. If you re-test right away, you will FAIL the Smog Test. This is because the car computer retains the old sensor data plus adds the new sensor data, and averages them both until the car computer re-sets again in 60 miles. After that I had the Smog Station re-test my car, and Pass it did.

IMPORTANT: On my car there are both "Upstream" and "Downstream" o2 Sensors. Make sure you Evaluate The Smog Test Fail codes carefully and Order The Correct Failing Sensor.

I hope my review helps, you Do It Yourself-ers should Save Even More!

BEWARE of Prime Source Distrib. 1/2 defective, refuse to exchange, bad seller. Then doubled price.

Reviewed in the United States on December 22, 2022

Verified Purchase

Do not order from Bosch store aka Prime Source Distribution, whatever name they have, one sensor was good, other one was a defect, they made constant excuses saying it was an install issue. They claim they're a 3rd party and do not accept return.
Tried to order a new sensor and they went from $28 to $52 from this same seller. Totally ripped off.

Good Value

Reviewed in the United States on February 20, 2020

Verified Purchase

Takes quite a bit of time to figure where to splice these into your existing system. You have 1 chance to splice the connectors correctly & figure out how the larger wire harness will fit in the existing wire protection box. That offsets the 1/2 or 1/3 cost of these relative to a factory or OEM part. Good quality part. On my VW with about 70k mi. there was corrosion on the wire connections that I didn't see until pulling the original part off. Bottom line - carefully check your wiring harness before buying the sensor. Corrosion is often the problem, not the O2 sensor.

not five like my 04 Volvo s60R

Reviewed in the United States on October 6, 2016

Verified Purchase

HAS FOUR WIRES, not five like my 04 Volvo s60R, does not fit. Check your car first before buying. It was wrongly advertised on the "check if part fits" section. For $100 at local auto parts store, bought the full Bosch sensor so no old parts were still used. Works great and totally worth it for having new part with both connecting ends of the part. I don't know now if I can return this part since it doesn't fit?

Universal Oxygen Sensors

Reviewed in the United States on March 15, 2013

Verified Purchase

I chose these sensors over the high cost of direct replacements. It is the exact same sensor that was on my car. It came with a 2 foot lead as discribed with some nice connecters. It has good instructions of how to install the sensor and connectors with how to make sure you attach the correct wires from the original sensor to the new one. The only issue I had was the location of the rear sensors on my 2002 VW Passat GLX V6. The space is very limited to get at the wires when trying to install the connectors. I ended up not using the supplied connectors. Instead I used spade connectors and heat shrinked the connection. I wanted to solder the wires but the space didn't allow it. If you have the ablity to completely remove the existing sensor and wire to either use the supplied connector or any other connecter that is water tight to keep the elements out so you won't short the sensor then this is great. I only installed them last night, so I can't say if it solved my error codes on the car, but I know with my scan tool that this was causing my fault codes. I glad I looked on amazon to find the sensor rather than dropping the money for the same sensor at the local auto store. I will use these again if I need too. Great find.

Gladly Buying a 2nd

Reviewed in Canada on December 13, 2020

I love this this, it's easy to install and the best part is you can attach any connector to it. I bought it for my car when I accidentally snapped the wires and it worked great. Buying it again for my new car where I once again accidentally snapped the wires when I pulled the engine to rebuild it. This is not a full sensor so keep the wire connection from you old O2 sensor. And if you can, leave at least 5" of wire on your old connector(just makes it easier to connect). Also, it is new not used(as I saw a picture of a comment, don't trust it, it's not real. It looks exactly like the photos from seller).

Just as I said, I love the product and will continue buying it as I need.
