🔌 Denso 234-4209 Oxygen Sensor with Connectors (not included) Review

This is a really inexpensive way to replace an OEM Denso sensor if you don't mind splicing the wires and waterproofing the connectors. I cut the wires on my stock O2 sensor so the connection point is inside the car. I used these amazing 50 pack heat shrink butt connectors from DEPEPE. Waterproof solder connectors 22-18 AWG red shrink butt connectors from DEPEPE that I had lying around after installing the stereo. The new O2 sensor works great (according to my OBD-II scanner) and reads the…

With extensive automotive experience, I only use Denso O2 sensors. This was supposed to be a replacement for the second bottom sensor on my Acura Integra. (upper (main) O2 sensor is new, Denso too) The process of replacing the lower sensor is much deeper. After doing further research after placing my order, I found that if there is no engine code/check engine light, the bottom thread does not need to be replaced. Downstream just checks that the catalyst is working properly. An old still working

Dakota 2000 4.7 liters, gas mileage almost halved, exhaust was fat. A computer scan showed an oxygen sensor and a high pressure sensor for the power steering reservoir. Apparently, if the pressure switch fails, liquid will squirt into the wiring harness and can contaminate the sensors. This happens on Dakotas and Darangos in early 2000. Not sure if this applies to other engine sizes. Of course when I replaced the one behind the catalytic converter there was oil in the quick coupler, the one in…

In short for Toyota Yaris 20101. Install this Denso oxygen sensor. 2. Clear the trouble code from the ECM. 3. Drive 10-20 miles 4. Scan the ECM to see if the code is still on or not. It fits Yaris 2010 Downstream (Heated Oxygen Sensor). After replacement, you may need to drive 10-20 miles to reprogram the ECM. Without driving you may be able to see the DTC again. The Yaris ECM appears to recognize this oxygen sensor after a specific drive cycle has been completed. It was embarrassing when I saw

I replaced both lambda sensors (top and bottom) on my Pontiac Grand Prix. Unfortunately, what I didn't know was that the upstream certified carbon sensor in California had a slightly different connector. I happened to buy a regular outlet sensor, so that wasn't a problem, but I had to, er, creatively change the upstream connector. Everything was going fine, the sensor was sending a signal and life was going fine until I got a CEL for the HO2S resistor that didn't go away. I checked the…

Exactly as advertised. This Denso part is the same OEM part for the more expensive turbo/supercharged Toyota/Lexus/Scion vehicles, so it will last hundreds of thousands of miles as the original part. If you have a decent set of wire crimps and wire strippers you can easily do this and save yourself half the cost and quite a bit of disassembly/assembly time like I did. The wires are color coded the same as the OEM and it doesn't matter which of the two black wires goes with which of the two…
