DTC P0734 A/T 4TH GEAR FUNCTION

DTC P0734 A/T 4TH GEAR FUNCTIONPFP:31940
DescriptionECS004RM

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 fourth gear position or line pressure is low 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
oil pump or torque converter clutch, etc.
CONSULT-II REFERENCE VALUE IN DATA MONITOR MODE
Remarks: Specification data are reference values.
On Board Diagnosis LogicECS00CU1
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 much lower than the position (4th) supposed by TCM, the slip ratio will be much
less than normal. In case the ratio does not reach the specified value, TCM judges this diagnosis malfunction.
This malfunction will be caused when shift solenoid valve A is stuck open or shift solenoid valve B is stuck
closed.
*: P0734 is detected.
And also, this malfunction will be caused when line pressure is lower than normal same as line pressure sole-
noid valve stuck open.
