- There is a misfire in cylinders 6 & 8. However, an internal transmission failure is also present. We recommend looking into transmission repair prior to going further with misfire diagnostics {customer contacted Automatic Transmission Experts who recommended repair of misfire prior to transmission repair} – Codes in system include: P0401 { EGR flow insufficient}, P0128 {thermostat below regulating temp} RECOMMEND THERMOSTAT – recommended previous visit as well, and P0327 Z{knock sensor 1 circuit low input – bank 1} – Lifted vehicle and found transmission level correct. Transmission is slipping which is an internal failure. Recommend taking to a transmission specialist for further diag and repair. – The part that fell off under bumper is a TPMS sensor antenna which will not cause running issues. – {DIAG CONT.} – Based on further diagnostic we are recommending a new thermostat, EGR valve and knock sensor to correct misfire/running issues. The knock sensor has been chewed off harness. Vehicle runs better when shorted knock sensor is disconnected. –
