DTC P0733 A/T 3RD GEAR FUNCTION
Revision: June 20062007 Versa
DTC P0733 A/T 3RD GEAR FUNCTIONPFP:31940
DescriptionUCS005O I

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 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 Diagnosis LogicUCS005OJ

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0733 A/T 3RD GR FNCTN” with CONSULT-II is detected when A/T cannot be
shifted to the 3rd 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 (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.

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 closed: 1, 1, 4* and 4 positions to each gear
position above
*: “P0733 A/T 3RD GR FNCTN” is detected.
