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.

ABS Light Due to Wheel Bearings and/or CV Joints With Excessive Runout

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.

Inspect transmission/fluid every 30,000 miles

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.
