When diagnosing the condition listed above on a common rail diesel vehicle, if no root cause is found after all GFF diagnostic procedures have been performed, it may be necessary to check for metallic particles in the high pressure fuel pump using the procedure in the Service section of this bulletin.
- [01146620306652](/bulletins/10228396.md), 2023-01-03, Service bulletin: FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING. The quality of the auxiliary exhaust gas recirculation \(EGR\) cooler modules manufactured within a certain timeframe may be inadequate. The vacuum actuator diaphragm may have leaks. A faulty auxiliary EGR cooler will trigger a P310E fault. Faulty operation of the auxiliary EGR cooler can also trigger the P040B fault, but there is no issue with the temperature sensor.
- [01146220361693](/bulletins/10228392.md), 2023-01-03, Service bulletin: FUEL SYSTEM, DIESEL; ENGINE AND ENGINE COOLING. In tank, fuel pump may be making a straining noise. Diesel fuel requires additive blending or ?winterization? to be useable at low temperatures. At temperatures below 20° F \(\-7° C\), No. 2 Diesel with insufficient winterization blending may lose its fluidity due to wax separation. This may clog the fuel filter or in\-tank filter, preventing the engine from operating properly. No. 2 Diesel is blended by refineries to various levels of winterization \(minimum useable temperature\) based on month, geographical location, and the 10th percentile minimum ambient air temperature for the given region. Although rare, during sudden periods of extreme low temperatures \(record lows\), fuel stations may not be adequately prepared with No. 2 Diesel fuel with sufficient winterization to resist wax formation or ?gelling?.
