When diagnosing this DTC, if pinpoint test (PPT) RD leads to Step RD27, proceed to Step RD28. This is due to PID NOx12 (NUM) incorrectly reading NOx11 (NUM) in the PCM. The NOx12 (NUM) PID will read the same as the NOx11 (NUM) PID. If the NOx Catalyst Conversion Efficiency Value PID reads less than 60% in Step RD28, replace the nitrogen oxides (NOx) sensor 12 and retest before replacing the selective catalyst reduction (SCR) catalyst. Engineering is investigating, monitor OASIS for updates.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10137146-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10137146-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10137146","components":[{"id":"engine","name":"Engine","parent":null},{"id":"exhaust-emissions","name":"Exhaust and emissions","parent":null}],"codes":["P20EE"],"topics":[],"vehicles":[{"make":"FORD","model":"F-650 SD","year_from":2016,"year_to":2018,"match":"base","vehicle_ids":["2016_ford_f-650","2017_ford_f-650","2018_ford_f-650"]},{"make":"FORD","model":"F-750 SD","year_from":2016,"year_to":2018,"match":"base","vehicle_ids":["2016_ford_f-750","2017_ford_f-750","2018_ford_f-750"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
