# Service bulletin 18\-073\-21

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin

## NHTSA's summary

Diesel Injector Freezing This bulletin involves installing a insulator over the Diesel Exhaust Fluid \(DEF\) injector. Customers may experience a Malfunction Indicator Lamp \(MIL\) illumination. Upon further investigation the technician may find that one or more of the following Diagnostic Trouble Codes \(DTCs\) have been set: P218F \- Reductant No Flow Detected. P202E \- \(Diesel Exhaust Fluid\) Reductant Injector Performance. The customer will not notice any drivability issues associated with these DTCs. These DTCs may set when the vehicles is parked for a long time and the ambient temperatures are below \-11 °C \(12 °F\).
