DTC P0733 A/T 3RD GEAR FUNCTIONPFP:31940
DescriptionECS004RI

This malfunction will not be detected while the O/D OFF indicator lamp is indicating another self-diagnosis
malfunction.

This malfunction is detected when the A/T does not shift into third gear position as instructed by the TCM.
This is not caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such
as control valve sticking, improper solenoid valve operation, malfunctioning servo piston or brake band,
etc.
On Board Diagnostic LogicECS00CTY
This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by TCM as
follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from ECM
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is higher than the position (3rd) supposed by TCM, the slip ratio will be more than
normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.
This malfunction will be caused when shift solenoid valve A is stuck closed.
*: P0733 is detected.
Possible CauseECS00CTZ
Check the following items.

Shift solenoid valve A

Each clutch

Hydraulic control circuit
DTC Confirmation ProcedureECS00CU0
CAUTION:

Always drive vehicle at a safe speed.

Be careful not to rev engine into the red zone on the tachometer.
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch OFF and
wait at least 5 seconds before conducting the next test.
TESTING CONDITION:
Always drive vehicle on a level road to improve the accuracy of test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
Gear position 1 2 3 4
Shift solenoid valve A ON (Closed) OFF (Open) OFF (Open) ON (Closed)
Shift solenoid valve B ON (Closed) ON (Closed) OFF (Open) OFF (Open)
Gear position supposed by TCM 1 2 3 4
In case of gear position with no malfunctions 1 2 3 4
In case of gear position with shift solenoid valve A stuck closed 1 1 4* 4
Diagnostic trouble code Malfunction is detected when... Check items (Possible cause)

A/T cannot be shifted to the 3rd gear posi-
tion even if electrical circuit is good.
