P0734 4GR INCORRECT RATIO
Description
INFOID:0000000005258024
This malfunction is detected when the A/T does not shift into 4GR position as instructed by TCM. This is not
only caused by electrical malfunction (circuits open or shorted) but also by mechanical malfunction such as
control valve sticking, improper solenoid valve operation.
On Board Diagnosis Logic
INFOID:0000000005258025
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0734” with CONSULT-III or 21th judgment flicker without CONSULT-III is detected
when TCM detects any inconsistency in the actual gear ratio.
Possible Cause
INFOID:0000000005258026
• Harness or connectors
(Solenoid circuits are open or shorted.)
• Input clutch solenoid valve
• Front brake solenoid valve

by the TCM in response to
signals sent from the output speed sensor and accelerator pedal position sensor (throttle position sensor).
Torque converter clutch piston operation will then be controlled.
• Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
• When the accelerator pedal is depressed (less than 1/8) in lock-up condition, the engine speed should not
change abruptly. If there is a big jump in engine speed, there is no lock-up.
