Review on Automotive Leader 234 9126 Upstream 2006 2011 36531 RNA A01 by Phillip Johnson

Vehicle: 2006 Honda Civic LX Coupe 5-MTI Reluctant to buy a non-genuine oxygen sensor at this price, let alone the upstream unit that sits right in the middle of the exhaust stream from everything a few centimeters away from the combustion chambers. I've had my check engine light on for a few weeks now and using one of the bluetooth odb2 readers as soon as the light came on I got an upstream O2 sensor error code. I checked all the wires for continuity with one of my multimeters and there were no opens in any of the 4 wires. I bought it as I began a fairly lengthy and extensive process of replacing almost everything suspension related such as the lower ball joints. lower control arms/front and rear end links/front struts + spring assemblies/rear shock absorbers, inner and outer tie rods, rear hub bearings, front rotors and pads, rear drums/pads/hardware/adjusters, spark plugs etc. Of course this sensor. I've put it all off, but I've owned this car since December 2015 and have driven it to a total of 12 miles out of 268,000. Everything but the front brakes and spark plugs was original from the factory, so it was definitely about time. This sensor was in the second of the three parts I have divided this repair into. On the one hand, the entire front suspension without struts and shock absorbers, and on the other hand, struts and shock absorbers, as well as candles and an O2 probe. The original sensor was a little tricky to remove but I used a PB blaster the night before and bought one of Revain's kits which included several types of tools to help with the process. A long socket with a slot in it worked best due to the recessed nature of the O2 sensors on this vehicle. To keep the socket from loosening at the bottom, I attached a circular actuating clamp at the bottom as recommended. A decent effort trying to keep the power parallel to the ground and it came right out. I cleaned the threads, lubricated with anti-seize and that was it. With the NGK laser iridium gauges removed and installed, it was time for a road test to check the dampers, spark plugs and gauges. The engine light went out immediately and hasn't come on since. For some datalogs, the output is identical to the desired factory sensor output. Couldn't be happier with it. The heating element heats up very quickly and the sensor itself even stabilizes a touch faster than the standard sensor. Works perfectly! Would happily buy again and recommend. I will update this review if the sensor stops working properly.
