DTC P0731 A/T 1ST GEAR FUNCTIONPFP:31940
DescriptionUCS005O8

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

This malfunction is detected when the A/T does not shift into first 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, etc.
On Board Diagnosis LogicUCS005O9

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0731 A/T 1ST GR FNCTN” with CONSULT-II is detected when A/T cannot be
shifted to the 1st gear position even if electrical circuit is good.

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 (1st) 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 either shift solenoid valve A is stuck open or shift solenoid valve B is
stuck open.

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 solenoid valve A stuck open: 2* , 2, 3 and 3 positions
In case of gear position with shift solenoid valve B stuck open: 4* , 3, 3 and 4 positions to each gear posi-
tion above
*: “P0731 A/T 1ST GR FNCTN” is detected.

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0732 A/T 2ND GR FNCTN” with CONSULT-II is detected when A/T cannot be
shifted to the 2nd gear position even if electrical circuit is good.

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 (2nd) 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 B is stuck open.

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 solenoid valve B stuck open: 4, 3* , 3 and 4 positions to each gear posi-
