This DTC can set when the pump temperature sensor signal is out of the expected range when coimpared to other temperature inputs. If the P142A code is encountered, clear the code and release the truck. Do Not replace the Diesel Exhaust Fluid (DEF) pump because it may result in a warranty chargeback, if the pump assembly is replaced when not required.
