I was getting P0171 and P0330 OBD codes. I cleaned the mass air flow sensor (MAF) with some MAF cleaner and the P0171 problem went away and the car started running nice again. The P0330 error code indicated that I had a bad knock sensor (bank 2, front of the engine). I took both knock sensors out and they passed the continuity test specified in the shop manual. I put it all back together and the car still would not shift into overdrive and was still setting the P0330 code. I took it back apart and replaced the indicated sensor as well as the sub-wiring harness that connects the sensors to the main wiring harness. That fixed the shifting problem and the P0330 error code.
The biggest downside of this was that I had to replace the $70.00 worth of gaskets again since I was not sure that they were reusable. They looked like they may have been single use crush to fit gaskets.
I also learned not to get parts from Lexus. Lexus has to buy their parts from Toyota, and then put their markup on that. Sometimes doubling the cost of the part. Instead, just go to Toyota and request parts for a camry.
