Problem Reported: Internal Transfer Case Problem on the 4WD models
February 27, 2011, 05:22 PM
<p>Ford Escape four wheel drive models may develop an abnormal noise from the <a href="/transfer-case">transfer case</a>. This may sound like a bearing howling first, but will turn into a clicking noise at higher speeds.</p> <p>The transfer case on these models is notoriously troublesome, and can become damage from normal use, and the sound of the failure is notably close to the noise heard from mud tires on pavement.&nbsp;</p> <p>To eliminate the noise, the vehicle should be inspected, and, if the transfer case has suffered internal damage, it must be replaced, not rebuilt.&nbsp;</p> <p>Changing the transfer case fluid on schedule may help, but many failures are before the first fluid change interval.&nbsp;</p>
Problem Reported: Inactive-Merged-Failure of EGR Differential Pressure Sensor
May 27, 2010, 11:09 AM
<p>The DPFE (differential pressure feedback EGR) sensor tends to fail. The DPFE sensor monitors function of the <a id="ce_8609" class="ct_glossary tooltip" href="/exhaust-gas-recirculation-valve">EGR valve</a> by measuring pressure changes in the <a class="ct_encyclopedia tooltip" href="/exhaust-gas-recirculation-system">exhaust gas recirculation <span class="ct_info tooltip">(EGR) system</span></a>. Symptoms of a failing DPFE sensor are hesitation or stumbling when driving along with illumination of the <a class="ct_auto care advice tooltip" href="/symptoms/check-engine-light"><span class="ct_selected tooltip">Check Engine Light</span></a>.</p>
