ALL OTHER DIAGNOSTIC TESTS AND CHECKS MUST BE PERFORMED when diagnosing one of the codes above if the tests below do not immediately reveal an issue. If an eService case must be submitted, ALL INFORMATION speci ed in Step Five MUST be included at the time the case is opened. Cases missing required information will be Refused. Overview Guided Diagnostics for SCR e ciency or NOx sensor fault codes will often result in No Fault Found. This often leads to replacement of one or both sensors despite no indication from diagnostic steps to do so. NOx sensor function is a possible cause, and is listed as such for the code description in the DTC description in Premium Tech Tool ( PTT ). However although the sensors themselves are a possibility, NOx sensor codes are most often a symptom, not a cause of emissions issues. NOx sensors should be con rmed to be reading incorrectly or functioning erratically before they are replaced. Fault Codes A complete list of DTCs related to this Solution can be found in the Fault Codes section below. Procedure UI ; Live - Review the Detailed Status Information for the relevant code https://volvo-trkna-prod1.pegacloud.net/prweb/PRAuth/app/VolvoKM_/iNPUIKpeinqPJi2G0hH930k43USdE1gb*/!TABTHREAD5?pyActivity=%40basec… 1/4 3/1/2021 Content creation stages KC-107 on the DTC Readout. • If Con rmed DTC is TRUE: Proceed with diagnostics • If Con rmed DTC is FALSE: Disregard and focus on other symptoms or DTCs relevant to the complaint. - A NOx Conversion should be run to check NOx sensor signal and function for any of the above codes. NOTE: A NOx conversion test only checks NOx sensor function. The test compares the readings of the two sensors as the engine cycles through multiple conditions to con rm they are in agreement. The results of the NOx Conversion test do not indicate anything about the condition of the SCR itself. 1. In PTT, run Operation 2549-08-03-03 NOx Conversion, located under the Test tab. 2. While running the routine if you get new NOx sensor fault code (Egs: P220E-93 , P220F-93), then troubleshoot that fault code. Typically P220E-93 fault code suggests replacement of NOx1 sensor. 3. Take screenshots of the graph and sensor values approximately 2-3 minutes prior to engine shutdown. A guide to taking screenshots can be found in THIS solution. - Inlet and Outlet NOx values should be within 40 parts per million (ppm) of one another just before the engine shuts down. Shown below is an example of how a graph with two properly functioning sensors will look: ; Live UI https://volvo-trkna-prod1.pegacloud.net/prweb/PRAuth/app/VolvoKM_/iNPUIKpeinqPJi2G0hH930k43USdE1gb*/!TABTHREAD5?pyActivity=%40basec… 2/4 3/1/2021 Content creation stages KC-107 4. If no issues are found with the sensor readings from the NOx Conversion review, the sensors are not the source of the conditions causing the codes to log. Further diagnostic steps of other components will need to be performed to determine the cause of the faults. 5. If this solution is being reviewed for P20EE, P207F, P225E or P103C, the DEF Dosing Valve Solution for the same DTCs should be reviewed for further information. 6. If diagnostic steps do not locate a root cause for the code(s), open an eService case with Dealer Technical Support - The screenshot(s) taken of the NOx conversion screen prior to engine shutdown (as shown in the screenshot above) should be attached to the case. - A complete summary of all tests performed along with numeric measurements, a DTC Readout, and any information concerning previous visits and parts replaced must be included when the case is opened. • "Ok", "Good" and "Followed GD" are not acceptable descriptions of tests performed and test results. - Add the solution numbers for all CBR articles followed. ; Live UI https://volvo-trkna-prod1.pegacloud.net/prweb/PRAuth/app/VolvoKM_/iNPUIKpeinqPJi2G0hH930k43USdE1gb*/!TABTHREAD5?pyActivity=%40basec… 3/4 3/1/2021 Content creation stages KC-107 Tags k15560422 p225e-00 p2201-64 p220164 p221a-00 p221a00 p225c-00 p225c00 p225e00 Related links and attachments KC-104 KC-908 Feedback Give feedback to help improve the content of this article ; Live UI https://volvo-trkna-prod1.pegacloud.net/prweb/PRAuth/app/VolvoKM_/iNPUIKpeinqPJi2G0hH930k43USdE1gb*/!TABTHREAD5?pyActivity=%40basec… 4/4
