Title (customer effect)
Diagnostic Trouble Codes ( DTC ) P2080, P2084, P242B Lighting The Malfunction
Indicator Lamp ( MIL ) - US14+OBD13 And OBD15 Emissions (Commonly Model
Years 2015 And 2016)
Cause
Diagnostic Trouble Codes ( DTC ) P2080, P2084, P242B can set due to incorrect
calculation of " soak " time of ambient temperature after key off.
Solution
Overview
Vehicles may exhibit the MIL lamp and one or any combination of the following fault
codes and symptoms:
ECM - Engine Control Module
P2080 - Exhaust Gas Temperature Sensor Circuit Range/Performance ( Bank 1 Sensor
1)
P2084 - Exhaust Gas Temperature Sensor Circuit Range/Performance ( Bank 1 Sensor
2)
P242B - Exhaust Gas Temperature Sensor Circuit Range/Performance ( Bank 1 Sensor
3)
Failure Mode Identifier ( FMI ) 64 - Signal plausibility failure
No Diesel Exhaust Fluid ( DEF ) Dosing
DEF will not be injected with these faults active.
Unable To Complete A Parked Regeneration
Aftertreatment Hydrocarbon Injector ( AHI ) injection will not take place with these
faults active.
Parked Regeneration Runs Too Long, And Does Not Complete
NO PARTS SHOULD BE REPLACED for these DTCs unless a sensor failure
is confirmed.
Repair
- Verify the chassis emissions level
- Details can be found in the Product Details box on the Product tab in PTT as seen below:
For US14+OBD13 (Commonly Model Year 2015) Chassis:
- Software improvements have been released to address this code. If any of these codes
are present, the following items should be checked and updated as necessary.
• Engine Control Module (EMS) Main Software (MSW) part number should be
22489791 or later.
• Parameter CWW should be set to 10.
If CWW is not set to 10, the Vehicle Electronic Control Unit (VECU) needs to
be programmed after the EMS.
For OBD15 (Commonly Model Year 2016) Chassis:
- Software improvements have been released to address this code. If any of these codes
are present, Engine Control Module (EMS) software should be checked and updated as
necessary.
• Main Software (MSW) part number should be 22644015 or later.
If Software is current:
- Review the Detailed Status Information for the relevant code on the DTC Readout.
• If Confirmed DTC is TRUE: Proceed with diagnostics
• If Confirmed DTC is FALSE: Disregard and focus on other symptoms or DTCs
relevant to the complaint.
Internal comments (BO)
No parts should be replaced for these fault codes, unless a definite sensor failure is found.
