Sorry. CEL. Check engine light. My brain is on slow this weekend. I'll give it a try.

No problemo, officially it's known as a MIL, not Mom I'd Like but rather malfunction indicator light. That's what the industry calls it. CEL is just more common because that's the text we see.
 
The code reader should be able to reset codes, but I'd read the instructions before using it. Some models can read but cannot reset, so make sure yours can do both.

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.
