1994 Toyota Corolla ProblemsCheck 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.
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.
You may be able to prevent automatic transmission problems by servicing the transmission and inspecting the fluid every 30,000 miles. If the fluid is dark or burned, the transmission system should be completely flushed.

Toyota is recalling 1993-1994 Corolla models because an unused harness connector for power windows, power door locks, and sunroof was improperly routed under the floor carpet in the left kick panel. In cold weather areas where road salt is used, the water from a driver's foot can penetrate the carpet, drop onto the connector, and form a salt bridge between the terminals. This can cause an electrical short, which may result in a fire. Dealers will remove the unused harness connector.
