PROBLEM
Show/hide table
| The existing 308-5087 Engine Electronic Control Group can fail to operate correctly on certain G3408, G3408C, and G3412 Engines when the NOx sensor has been replaced with a new sensor. If the existing Air/Fuel Ratio Controller fails it will lead to improper NOx sensor operation. The NOx sensor will continuously cycle in and out of heating and active operation. |
