## Description

Denso 234-4168 Downstream Oxygen Sensor with 4-Wire 13.7” Harness

Review: So far ZERO issues!! worth every penny!!! - fit perfectly, the cable was a little thinner then the OEM, I assume it was upgraded technology in the heat resistance material, or at least I hope so!! I've been told DENSO is the maker of OEM Toyota o2 sensors, so I had no issues purchasing this one. so far it has worked like a charm! it was a lot cheaper then OEM, desertcart Prime shipped it free so it was totally worth the chance. It was difficult to get my 15 year old factory o2 sensor out but once I did this one went right into place and connected right into the factory wire connector. My check engine light went off for the first time in 4 years.
Review: Always go with OEM electrical replacement parts bought from reliable vendors on desertcart. - I had the check engine light pop up on my 2006 Toyota Sienna. My OBDII meter indicated a weak catalytic converter which can actually mean a malfunctioning O2 sensor. Sensors are a lot less expense than catalytic converters so I elected to replace them first. The dealer wanted way too much for the OEM sensors so trying to save money; I bought a complete set of no brand sensors from turbosisland in California online off EBay. They were guaranteed to fit my van. None of the no-brand sensors worked. The whole effort was a waste of my time and money. I then ordered OEM sensors from desertcart.com services. They are OEM parts so they were still a little pricey but they were priced much lower than the dealer or any of the auto parts stores near me. They arrived quickly and were an exact match for my original sensors. They even came packaged with a small tube of antiseize compound. Before starting the removal of the O2 sensors, as a safety precaution, I disconnected the van battery. Removing the old parts was a bit of a pain as the electrical connector clips on the old parts were hard to get apart. To make unscrewing the sensors easier, I sprayed them with penetrating oil the day before and ten minutes before trying to unscrew them. After I disconnected the stubborn wire connectors, I used the tool made for removing O2 sensors and easily broke them loose and finished unscrewing them with my fingers. Reinstalling the new sensors is fast and easier than removing them because the electrical connections snap easily back together. After installation of the sensors, my van’s engine is running smooth again, my gas mileage has returned, and the check engine light has not come back on. In the future, I now know to stick to OEM electrical parts for my vehicles and to buy them from reliable vendors on desertcart.
