P0734 4GR INCORRECT RATIO
DescriptionINFOID:0000000005928158
• This malfunction will not be detected while the OD OFF indicator lamp is indicating another self-diagnosismalfunction.
• This malfunction is detected when the A/T does not shif t into fourth gear position or the torque converter
clutch does not lock up as instructed by the TCM. This is not caused by electrical malfunction (circuits open
or shorted) but by mechanical malfunction such as c ontrol valve sticking, improper solenoid valve operation,
malfunctioning oil pump or torque converter clutch, etc.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000005928159
Remarks: Specification data are reference values.
On Board Diagn osis LogicINFOID:0000000005928160
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0734 4GR INCORRECT RATIO” with CONSULT-III is detected when A/T cannot
be shifted to the 4GR position even if electrical circuit is good.
• This diagnosis monitors actual gear position by checki ng the torque converter slip ratio calculated by TCM
as follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from output speed 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 pos ition (4th) supposed by TCM, the slip ratio will be much
less than normal. In case the ratio does not reach t he specified value, TCM judges this diagnosis malfunc-
tion.
This malfunction will be caused when shift solenoid valve A is stuck open or shift solenoid valve B is stuck
closed.
• Gear positions supposed by TCM are as follows.
In case of gear position with no malfunctions: 1, 2, 3 and 4 positions
In case of gear position with shift so lenoid valve A stuck open: 2, 2, 3 and 3* positions
In case of gear position with shift sol enoid valve B stuck closed: 1, 2, 2 and 1* positions to each gear position
above
*: “P0734 4GR INCORRECT RATIO” is detected.
Possible CauseINFOID:0000000005928161
• Shift solenoid valve A
• Shift solenoid valve B
• Line pressure solenoid valve
• Each clutch
• Hydraulic control circuit
