I have less than 9500 miles on a brand new 2006 Sienna XLE. It has been in the shop 4 times on various problems. The latest is ABS,VSC and TRAF OFF lit up on the dashboard. The service Dept. replaced ABS/TRAC Actuator Assy. Does anyone have the same issue with your van, and btw I'm not impressed with the MPG either... TIA, saafedt

I too have the check engine, vsc & trac off lights on . I went to auto zone , atre scanning , the code indicates air/fuel sensor heat circuit response. (bank 1 sensor 1) it says probable causes 1. open or short circuit condition 2. poor electrcal connection I would guess to start looking at the electrical connections at bank 1 sensor 1 , but what is that ? cylynder 1 or what . I 'd appreciate any help .

turns out , the trouble code indicated bank 1 sensor 1 . air/fuel sensor heat response circuit. these are toyota's version of an o2 sensor . the heat circuit is added to make it get to operating tempature faster . on the sienna ,there are 3 .one on each exhaust manifold & one downstream of the cat. they all work in conjunction w/each other to make adjustments. bank one is the first , next to the firewall, two is in front just behind the radiator , & three is last after the cat. at toyota , the sensor was $210 so, I bought it on the net from a toyota dealer fo $158, delivered. comes w/ a dab of antisieze on the threads. you're supposed to check the 02 sensor w/a voltage meter . there are paramaters to check if the part is in fact bad b4 buying an expensive replacement .

On 2007 LE I am getting dual warning. On the top left by F(full) of fuel gauge I have a lighted triangle with display of FUEL DOOR and at bottom of the gauge by E(empty) I have a lighted gas pump symbol. I did fill up the tank and close the fuel cap to one click and fuel door secured. Both the warning indicators still remains. Does any one have a similar problem/resolution?

I have a 2007 Sienna Limited. For only three months (< 5k), one day I got tire pressure light on while driving on the highway. It's so scare so I had to find a safe place to check tire pressure, but just to find out they all normal with 35psi!? Then I went to the local dealer for help. First two times they could not find anything wrong so they just reset the button. The third time they told me they found the problem and had to replace the computers (sensors??). But the warning light still comes on the next day. After three visits I feel they may not know what the problem is. So I come here for a suggestion. Also wondering am I the only one has this problem??
