DTC P0733 A/T 3RD GEAR FUNCTION
Description
INFOID:0000000001724390
This malfunction is detected when the A/T does not shift into 3rd gear 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:0000000001724391
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0733 A/T 3RD GR FNCTN” with CONSULT-III or 20th judgment flicker without
CONSULT-III is detected when TCM detects any inconsistency in the actual gear ratio.
Possible Cause
INFOID:0000000001724392
• Harness or connectors
(Solenoid circuits are open or shorted.)
• Input clutch solenoid valve
• Front brake solenoid valve
• Direct clutch solenoid valve

by the TCM in response to
signals sent from the vehicle 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.
