Amrxuts 234-9066 Upstream Air Fuel Ratio O2 Oxygen Sensor (2004-2008 TSX 2.4L) Review

Perfect for my '06 Acura TSX 6 speed 4 cylinder. At first the mechanic said it didn't fit and that it should be easy, but with a little more effort he finally made it ✅

Right part number for 2004 Acura tsx. I have previously bought an O2 sensor from another seller at a lower price and ended up finding one that connects but doesn't work, but this one works out of the box.

So far so good. Installed it on Friday for (P0135) bank 1 sensor 1 air fuel ratio sensor. Installed, cleared code and didn't come back. I'm leaving for a few days. Received in good condition 👍🏽

This sensor helped my 2007 tsx with the annoying p0139 code. I replaced the second sensor because it kept giving me a code saying it was slow to respond, bank 1, sensor 2. I found out the one I bought needed to be replaced.

I was very surprised by this. I had P1172 and P2A00. I usually ride OEM sensors but the price was too high for me at the time. I tried it for a quarter of the price and it really solved the problem. Idle jerking and voltage peaks are eliminated.

This solved my CEL code P0135 (O2 Sensor Heater Circuit Bank 1 Sensor 1) on my 2005 Acura TSX. It was a direct correspondence to the old part. When I pulled the old sensor out, part of the heater circuit was open causing my CEL to light up as soon as the engine started, even after the codes were cleared. The CEL didn't come back after about 50 miles and I was able to pass the local emissions tests (after driving the car enough to complete the OBDII readiness tests).
