Review on Denso 234 9049 Air Fuel Sensor by Michael Syph

Low Current Sensor 1 DLC Bank 1 (P0031) Searched the Denso website for the correct part. It turned out that if 234-9041 is not available, the description is given under the order 234-9049. Using a voltmeter, I checked the "open" on the sensor's heating element. It was really "open". By the way, be sure to clean the connector (on the wire harness side, not the sensor side) with an electronic cleaner such as CRC QD Cleaner. Our Camry has over 143,000 miles on the clock and it turned out that the contacts were dirty or corroded. If the code comes back or there are other issues with the sensor I will update the review. So far it works great and is very easy to install. Do not get under the car to do this.
