A rough idle and even an emissions inspection failure for high HC and CO can be caused by improperly adjusted valves. Also, exhaust valves may become to tight which can lead to valve failures. Our technicians tell us that regular valve adjustment inspections are a must.
The anti-lock brake system (ABS) may function erratically or illuminate the warning light due a damaged wheel speed sensor. A wheel bearing and/or CV joint with excessive runout can cause the ABS trigger rings to rub against the ABS sensors and damage them.
Typically the AC compressor is worn out by about 150,000 miles in warm and/or humid climates. It is recommended to replace the complete compressor including a new clutch and rpm sensor, and to replace the receiver/dryer as well.
The AC Expansion Valve may develop a very slow leak or allow too much refrigerant flow which reduces cooling. Our technicians tell us that Toyota makes an updated expansion valve to resolve these problems if and when they occur.
