TSB 20-2270 & That Urea Sensor Tool

[Keith Browning]

Rotunda tool number 418-665 if you have not seen it you should go find it in your dealership.

This article supersedes TSB 17-0067 to update the Service Procedure and Parts List. Issue: Some 2017 F-Super Duty vehicles equipped with a 6.7L diesel engine built on or before 04-Aug-2017 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P203B. This may be due to a low voltage condition during engine cranking. To correct the condition, reflash the diesel exhaust fluid (DEF) reductant level sensor/quality module using the Urea Sensor Reprogramming tool. Action: Follow the Service Procedure steps to correct the condition on vehicles that meet all of the following criteria:   • 2017 F-Super Duty • 6.7L diesel • Built on or before 04-Aug-2017 • Illuminated MIL with DTC P203B
