Review on 🚀 Enhance Your Engine's Performance with Denso 234-4122 Upstream Oxygen Sensor and 21” 4-Wire Harness Female Plug by Jeff Bundrick

This Denso 234-4122 is the correct part for the lower O2 sensor for my 2001 Accord LX 4cyl vtec-ulev. Oddly, prior to the replacement I had the wrong O2 sensor and had no codes. Just weird O2 readings. The figure shows the data from the previous sensor. However, upon installation I immediately received a code for a faulty heater sensor circuit 02. Removed and checked the voltage/ohms. Shows more than 1V and only 3 ohms between the two black wires. According to the data sheet it should be 20-40 ohms. Guess it might just be bad luck. Once the return/refund is complete I will order again and try my luck again. And update the results.
