DTC Troubleshooting: P0920 (162-7)
Change the shift lever from D to N, then from N to D, and measure voltage between shift actuator motor 6P connector terminal No. 6 and body ground.
Does the voltage change from 0 V (or battery voltage) to battery voltage (or 0 V) depending by the shift lever operation?

Remove the clutch actuator assembly; R18A2 engine model,

and check for change actuator subharness A. If the wire harness is OK,
update the TCM if it does not have the latest software
or
substitute a known-good TCM,
then recheck. If the symptom/indication goes away with a known-good TCM,
replace the original TCM; R18A2 engine model,
L13Z1 engine model.
