Initially the Exhaust Gas Recirculation Valve (EGR) on this 2019 Opel/Vauxhall Vivaro indicated a parameter mismatch on the scan tool between the actual and desired valve position, yet no signs of damage was apparent on the connector and terminals. After further diagnosis, the EGR measured proper specifications but it wasn’t until the “hood was opened” to reveal the real culprit of carbon clogging the valve.
The real fix on this 2019 Peugeot Boxer’s NOx sensor began diagnostic testing with a scan tool to identify proper specifications for the signal compared to the actual signal omitting from the NOx. With the signal parameter above specifications but with present voltage, no damage or short, the community came to the conclusion that the sensor itself was faulty and was able to quickly return the vehicle to safe operating condition after the replacement.
