Problem Reported: Failed Emissions Test Due to Blocked EGR System
September 15, 2010, 10:06 PM
<p>The <a id="ce_9145" class="ct_null tooltip" href="/exhaust-gas-recirculation-system">EGR</a> 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 <a class="ct_auto care advice tooltip" href="/understanding-the-check-engine-light"><span class="ct_null tooltip">Check Engine Light</span></a> 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.</p>
