## NHTSA's summary

Customer Satisfaction Notification T23 ? EGR Valve Function The Powertrain Control Module \(PCM\) on about 415,000 of the above vehicles has software that may be operating the Exhaust Gas Recirculation valve \(EGR\) with an aggressive seating velocity. An aggressive seating velocity may damage the EGR valve. As a result this condition may illuminate the Malfunction Indicator Lamp \(MIL\) and display a P0404 code. The PCM must be reprogrammed on all involved vehicles.
