Toyota Supra Problems

Check Engine Light Due to Restricted EGR System

The EGR System tends to get restricted or blocked with carbon after 100,000- 125,000 miles which will cause an emissions test failure for NOX. If the EGR system is equipped with an EGR temperature sensor it will trigger a Check Engine Light for improper EGR flow. The repair is to clean out the EGR passages and the EGR Temperature sensor. Our technicians tell this repair is pretty straight forward and takes about 1-1.5 hours. It is also wise to verify the EGR system components i.e. the Transducer, EGR Valve and VSV Solenoid at this time.

Automatic Transmission May Not Shift Correctly at High Mileages

At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.

Replace coolant and thermostat every 60,000 miles

Our technicians tell us that it is important to change the coolant with factory coolant and replace the thermostat every 60,000 miles. This will help to protect the head gasket, otherwise the head gasket can deteriorate and be stressed to the point of failure.
