9/27/21, 11:44 AM Article Diagnostic Trouble Codes (DTC) P208064, P208464, P242B64 and P246F64 Lighting The Malfunction Indicator Lamp (MIL) - US17+OBD19 And Newer Emissions, Model Years 2020 and Newer Internal Content No parts should be replaced for these fault codes unless a definite sensor failure is found. Fault Tracing Procedure: 1. Allow the vehicle to sit until the engine and exhaust have reached ambient (air) temperature. 2. Turn the ignition to ON, engine OFF. 2. Using Premium Tech Tool (PTT), run either of the operations below: • 2545-08-03-02 Exhaust Aftertreatment Diagnostics, option A - This will provide a numerical view of exhaust temperatures. • 2589-08-03-02 Exhaust Aftertreatment System, Service Regeneration - This will provide a graphical view of exhaust temperatures. 3. Ensure that the sensor readings are within 10 °C (18 °F) of one another before starting the engine. 4. Start the engine. 5. Monitor exhaust temperatures on PTT: • The sensor temperatures should rise in the order of 1, 2, 3, 4 as shown below after starting the engine. 6. Evaluate results: ; Live UI • If the sensor readings are equal at ambient temperature and rise in the correct order when the engine is running: No further fault https://volvo-trkna-prod1.pegacloud.net/prweb/PRAuth/app/VolvoKM_/iNPUIKpeinqPJi2G0hH930k43USdE1gb*/!TABTHREAD1?pyActivity=%40basec… 1/3 9/27/21, 11:44 AM Article in the correct order when the engine is running: No further fault tracing should be performed. Clear the DTCs and return the vehicle to service. • If one or more sensors are displaying a different reading from the others or are spiking instead of smoothly increasing with the engine running: The sensor(s) should be suspected to be faulty. • If the temperature sensor values rise out of order: The sensors should be checked to ensure they are installed in the correct positions. An example of proper temperature sensor function when engine is cold (shutdown overnight). All 4 temperature sensors are expected read within 10F of each other and ambient temperature. Once engine is warmed (idle for few minutes), taking vehicle to high idle (>1000rpm) typically should show temperatures similar to picture below. T1 > T2 > T3 > T4. NOTE: T4 is only valid for OBD19 and Newer Vehicles. ; Live UI https://volvo-trkna-prod1.pegacloud.net/prweb/PRAuth/app/VolvoKM_/iNPUIKpeinqPJi2G0hH930k43USdE1gb*/!TABTHREAD1?pyActivity=%40basec… 2/3 9/27/21, 11:44 AM Article This CBR will be updated when new information is available.
