You need to locate the speedo wire, it can go like this. read wheel to the abs. to the sunroof motor to the auto box then ecu, and anything else before it gets to the speedo in the dash any one of these were is not connecting properly can give this code. also check the cog on the read wheel make sure its not mucked up. also if the abs is not lite up to say there is a fault its not that part that is the problem.

well that's if I'm not mistaken, catalyst system efficiency THRESHOLD!!! it is "bank" when your description code explanes bank 1 that is a O 2 sensor anything says BANK is a Oxygen sensor = O 2 sensor.what is it doing shutting off when eng warms up or sputtering or nothing really out of normal behavior? these switches will loose all communication with computer or get stuck in 1 of three ranges each range behave differently! in each range the deal with these are these switches are a part of maintenance usa @ hundred thousand km they should be change for emission efficiency and fuel consumption and vehicle performance usually after 1 is changed 9 times out of 10 shortly after the next bank will produce eng light and so on!! I usually change both while I'm at it you know pay me now or pay me again later but twice as much! well hope this helps you out good luck cheers happy new year.John, Toronto,Ontario

hello, to fix this problem what you need to do is replace your egr valve its a pretty straight forward replacement ,to get a new one goto any auto parts store and tell them what you need thay all carry egr valvs in stock cost is about 30.00$
SOURCE: 1997 toyota camry check engine light on,code po440,po420,po441,
P0420 is catalyst system efficiency below threshold (bank 1)
P0440 is evaporative emission control system malfunction
P0441 is evaporative emission control system incorrect purge flow

They are not the sensors you want. The car uses the abs wheel sensors for vehicle speed. Your problem lies in the abs system , possibly the left front sensor, abs ecu or speedo cluster, Clear the code and see if it stay out otherwise you'll need to go to a trusted technician. .
The 1998 Sienna has one speed sensor in each tire (ABS sensors.) These sensors are used by the ABS system, but also to calculate the vehicle speed and for the tire air pressure monitor. If you are getting a P0500 code and your speedometer does not work, your problem could be a faulty speedometer. If one of the speed sensors were bad, the low tire air pressure light would come on.
