An update on the error code. Ran the tank all the way down and filled it up. Reset the CEL, and it came on after about 5 miles. Had the o2 sensor replaced at the dealer, $297 cost. The good thing was they found a leak somewhere in the radiator which just happened to be under warranty by 6 months. They replaced the radiator, so I guess it worked out well in the end. Thanks for your help, and suggestions.

2005 Sienna, 99,000K. 2WD. I also use LUCAS cleaner before the 3 lights (CEL, VSC, Trac off) come on. The code is p0037. Where is the B1S2 located ? and how to reset, EFI1 or EF 2 fuse ?

Peterchan, from what I recall, the B1S2 sensor is located in front of the firewall. I found a diagram somewhere on line but deleted it a while back. I reset the warning lights using a OBII tester a few times, but the lights always came back on. I ended up taking van to the dealer and got dinged for $300 for replacement and labor. It looked a little too involved for me to do the job. Lucas must burn the sensor. That was the one and only time I used the Lucas product. Good luck. Let me know what happens if you don't mind.
