DTC Troubleshooting: P0920 (162-7)
DTC P0920:
 Shift Actuator Motor System Malfunction
  1. Turn the ignition switch to ON (II).
  1. Clear the DTCs with the HDS.
  1. Check for DTCs with the HDS.
Is DTC P0920 indicated?
YES -
Go to Step 5 .
NO -
Intermittent failure, the system is OK at this time.■
  1. Turn the ignition switch to LOCK (0).
  1. Reconnect the 6P connectors to the transmission shift change actuator.
  1. Turn the ignition switch to ON (II).
  1. Change the shift lever from D to N, then from N to D, and check the shift actuator rod (A) operation.
Does the shift actuator rod move smoothly?
YES -
Repair the transmission internal failure.■
NO -
Go to Step 10 .
  1. Turn the ignition switch to LOCK (0).
  1. Disconnect the shift actuator motor 6P connector.
  1. Change the shift lever from D to N, then from N to D, and measure voltage between shift actuator motor 6P connector terminals No. 1 and No. 6.
Does the battery voltage change from positive (or negative) to negative (or positive) depending by the shift lever operation?
YES -
NO -
Go to Step 13 .
  1. Change the shift lever from D to N, then from N to D, and measure voltage between shift actuator motor 6P connector terminal No. 1 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?
YES -
Go to Step 14 .
NO -
Repair an open in the wire between the TCM and the transmission shift change actuator.■
  1. 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?
YES -
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. ■
NO -
Repair an open in the wire between the TCM and the transmission shift change actuator.■
