Description of the problem	Faulty electronic computer module on 2003 toyota highlander throws multiple error codes to indicate a number of problems with emission components. Error codes call out oxygen sensors, (there is four sensors on 2003 (4) cylinder highlanders). Fix one sensor and another pops up bad according to the error codes. Another $400 repair bill ! Toyota will replace the module on cars with warranty, no problem. However, they deny there is any problems with the module when no warranty is involved. Codes at times also show a faulty catalytic converter ($1000 repair bill ). If you visit the toyota nation web site you will see many reports of the component at issue. This is on the same vehicles as the one i own. Some people have reported toyota charges unsuspecting customers $1600 to repair these four sensors. ( not my words, taken off the toyota nation forums). Please demand toyota replace the modules on these vehicles. Thank you !
