I purchased my integrated relay from the local Toyota dealer.

#8 of 12 2000 sienna p1150 ? by whiley

Sep 11, 2010 (11:31 am)

I'm getting an obd code p1150 and eventual {p1155pd pending?} from what I have read this refers to a oxygen-sensor bank 2 sensor 1 which I believe { I wanna believe because" I think "this is the one (p1150)on the radiator side not the firewall side which is harder to access} the "pending"p1155pd is a result of the faulty p1150 again I think,before spending hard to get cash and time I was wodereing if anybody had any advice which would help me I've read that it "re setting?" the EIF relay will fix the problem,looked for a reset on the relay and could'nt find it . prior to getting this error I had just changed the oil and filter (checked area for loose electrical connectors) and my wife said the gas level was low and vehicle was running sloppy "prior" to error code coming on...any help/suggestins would be greatly appreciated

I have a Toyota Sienna 2000 and it has serious electrical problems. When I open the door with the key or the remote the alarm sets off every time. Also while I am driving the door lock unlocks and locks by itself, then my left turn signal does not work properly. It flashes rapidly and the signal does not show for other drivers to see. Whoever has or had a similar problem before and fixed this problem please contact me and inform me to fix this issue. I will greatly appreciate your help, my email address is maggicanadahotmail.com. Thank you very much.

I have a 200 Toyota Sienna XLE it has been a great third car. Last week my seat belt light on dash came on while it was locked in. Then I noticed the door adjar symbol on dash, these issues are new and it seems to be setting the alarm off randomly. Any advise before I head to dealer??

Chances are it's the Integrated Circuit Relay which seems to fail and causes strange electrical issues(side door won't open/close, seat belt lights stay on, overhead lights stay on, et al)
 
I replaced the Integrated Circuit Relay with Door Control, P/N 82641-08020 because of similar electrical problems. Part costs $200 dealer only. If you are military, ex-military or senior citizen, many Toyota dealers offer a 10% discount on parts, so ask for it.
 
It took me about 4 hours to put it in. Don't try this unless you have infinite patience, an advanced set of tools, a LED trouble light, a thick sleeping bag to lay on, and some basic knowledge about auto electrical. You will have to disconnect the battery, remove the two dash panels under the steering wheel, remove the driver seat, the driver's side running panel and the driver's side kick panel. Then, laying on your back (on the sleeping bag) with your head under the driver's side dash compartment, you have to completely disconnect most of the connectors to the fuse box (located on the firewall) so you can drop it down. Once the fuse box is down, remove the old unit which is mounted on top of the fuse box. Then, mount the new one. This is one of the more challenging ones I've tackled because of the tight space you're working in and compactness of the wiring. It did fix my problem and I haven't had electrical issues since (knock on wood). PM if you wish.

I don't know if this is the integrated switch that everyone is talking about.. It might be.. But i do know that there were odd issues on mine too, and it turned out to be an issue with water seeping into the van through the rear hatch. After cleaning up the water, and adjusting the rear door.. the problem went away... I would check to see if your carpets are wet... Good luck..
