The NOx sensors incorporate an electric heater that is controlled by the NOx module to quickly bring the sensors to operating temperature. As moisture remaining in the exhaust pipe could …, P20EE Code Duramax. The P20EE means SRC NOx Catalyst Efficiency Below Threshold. Here the SRC denotes selective catalytic reduction catalyst on a Duramax diesel engine. And NOx stands for nitrogen oxides. So when PCM detects catalyst efficiency is below the threshold on bank 1, the p20ee code Duramax 2021 appears., In This video I go through all the steps to troubleshoot Poor Quality DEF Warning., The NOx sensor should be about the last one in a line of the bunch. And yes, I believe an Alldata subscription would be helpful. Not only for location and description, but also the pinout of the connector, and perhaps an alternative for the connector that GM has but doesn't have. I don't have any L5P Alldata subscriptions (haven't had a need, yet), …, In 2020, GM’s engineers overhauled the trucks and increased tow capacity by 52%. 2020 Chevrolet HD and GMC HD trucks with L5P Duramax engines have a max tow capacity of 35,500 lbs. …, P20EE Code Duramax. The P20EE means SRC NOx Catalyst Efficiency Below Threshold. Here the SRC denotes selective catalytic reduction catalyst on a Duramax diesel engine. And NOx stands for nitrogen oxides. So when PCM detects catalyst efficiency is below the threshold on bank 1, the p20ee code Duramax 2021 appears., Diesel Particulate Filters DPF, Diesel Oxidation Catalysts DOC, Selective Catalytic Reduction SCR - Emission Sensors: NOX, EGT, O2, Particulate Matter, Pressure - Nitrous Oxide (NOx) Sensors; Chevy/GMC Duramax Parts - 2017+ Chevy/GMC Duramax L5P 6.6L Parts - Diesel Particulate Filters, DOCs, SCRs | 2017+ Chevy/GMC Duramax L5P 6.6L, DuraTrey. 136 posts · Joined 2020. #2 · Nov 10, 2021. These emissions systems are the debil. I doubt the failed NOX sensor caused the DPF problems, but maybe vica-versa. Maybe the DPF problems should be covered under the emissions warranty and that lasts longer than two years and 65K.
