Enhanced Denso 234-2000 Oxygen Sensor for Improved Engine Performance Review

I also had to replace this one. Gave me problems on day one. Caused a real backswing and gave 9 different codes including a full pull sensor code. After replacing all the sensors I bought from Amazon, all my codes disappeared.

Perfect for our 1989 Mazda B2600i. This is a better quality two wire (ground and voltage) sensor than what you can buy at your local store like Autozone. And the price is much better! Overall very satisfied and if we need it again we will buy another one (hopefully not).

Designed for universal single-wire systems, but actually has 2 wires! The second wire is ground! It's probably an acceptable design, but the description should tell you that, unlike other generic devices, that's how it was made. Otherwise, like me, you'll send it back as the wrong part and waste time (but no money - Revain will pay for the return shipping). I ended up with an aftermarket unit rather than a Denso which I would have preferred to use. Not cool guys, not cool. I hate leaving bad…

I needed two new sensors for my Corolla. The workshop listed $160 each plus installation. It sounded a bit pretentious, so I went online and did my homework. I found this sensor and a similar one according to the manufacturer's requirements. However, these universal sensors don't come with a connector, but that's the part that doesn't wear out. You can use the old plug. With a bit of soldering and some tape I saved over $200 in parts and installed them myself (it was easy for my machine). Since
