    摘要: A system comprises a post oxygen performance diagnostic (POPD) module that performs a POPD of a post oxygen sensor, wherein the POPD includes a deceleration fuel cutoff (DFCO) portion. A torque converter control module adjusts operation of a torque converter clutch (TCC). The POPD module and the torque converter control module operate the TCC to control engine speed above a predetermined engine speed during the DFCO portion of the POPD. A method comprises performing a POPD of a post oxygen sensor, wherein the POPD includes a deceleration fuel cutoff (DFCO) portion and adjusting operation of a torque converter clutch (TCC) to control engine speed above a predetermined engine speed during the DFCO portion of the POPD.
