Good morning,
I am wondering if anyone else has had this problem?
I got a code of P1647 bank 2 upstream O2 and replaced it and cleared the code, then after about 3 miles the check engine light cam back on, and sure enough the same code reappeared.
Anu ideas of what it could be?
Thank you, Sean

Ok update. I worked on it this weekend and I have ohms readings on both upstream sensors of 1.2 I have power going to Bank 2 upstream. I attached a test light across the heater circuit wires and turned on the ignition and the test light lit up for a few seconds and then turned off. I hooked up the scanner and it is showing no voltage fluctuation reading for both upstream sensors. Erase code and it comes right back. Has anyone had this problem before. I am at a loss! Any help would be much appreciated. Thank you

PROBLEM SOLVED! I spending hours testing, I ran across an article online talking of fake Denso O2 sensors, and sure enough The first one I purchased off Amazon was a fake. Bought a new one at a local parts store last night and problem gone.

On the Lexus forum but still applies of how to spot a fake Denso sensor (no part number ON the sensor = real, WITH a part number = fake) =

The #4 about the lead wire is interesting. This might be a major reason so many eBay and Amazon clones cause problems.
