TROUBLESHOOTING (DTC P0753/P0758)
STEP
1 Was "A/T DIAG. FLOW TABLE" performed?
2 Is the vehicle equipped with monitor connector?
3 Is DTC NO.61 or 63?
4 Check Shift Solenoid Circuit for Open or Short.
1) Turn ignition switch OFF and disconnect PCM
connectors.
2) Check for proper connection to PCM at terminals
C51-1-2 for G16/J20 (C51-1-6 for H25) or C51-1-1.
3) If OK, then measure resistance between terminal
C51-1-2 for G16/J20 (C51-1-6 for H25) or C51-1-1
of disconnected PCM connector and ground.
Is it 11 – 15 f at 20_C, 68_F?
5 Check Shift Solenoid Circuit for Short.
1) Turn ignition switch ON.
2) Measure voltage between terminal C51-1-2 for
G16/J20 (C51-1-6 for H25) or C51-1-1 of
disconnected PCM connector and ground.
Is it about 0 V?
6 Check Shift Solenoid Circuit for Short.
1) Turn ignition switch OFF and disconnect PCM
connectors.
2) Check for proper connection to PCM at terminals
C51-1-2 for G16/J20 (C51-1-6 for H25) or C51-1-1.

C51-1-2 for G16/J20 (C51-1-6 for H25) or C51-1-1
of disconnected PCM connector and ground.
Is it 11 – 15 f at 20_C, 68_F?
