Title (customer effect)
Volvo Chassis - Diagnostic Trouble Code ( DTC ) P226C Intermittently Lighting The
Malfunction Indicator Lamp ( MIL ) - US14+OBD13, US14+OBD15 And
US14+OBD16 Emissions (Non-Common Rail Fuel System), Commonly Model Years
2015 to 2017
Cause
US14+OBD13, US14+OBD15 and US14+OBD16 (Commonly Model Year 2016 and
2017) chassis may intermittently log DTC P226C
Solution
Overview
US14+OBD13, US14+OBD15 and US14+OBD16 (pre-common rail) conventional chassis
may log DTC P226C during operation. The diagnostic process that this DTC sets for is the
monitor of boost pressure change under sudden changes in engine load. The code is likely to
set intermittently and it may be difficult or not possible to duplicate during diagnosis. Guided
Diagnostics may result in No Fault Found (NFF). This issue is more likely to be observed in
chassis with a 13L engine and a lower power rating, and chassis with dual torque engine
ratings. This code will not affect performance or driveability. Turbocharger replacement is
not a valid repair for this code.
Repair
