7A–36 AUTOMATIC TRANSMISSION (AW30-40LE)
DTC P0722 (FLASHING CODE 11) OUTPUT REVOLUTION SENSOR FAILURE (SP2)
D07RY00018Circuit description:
Vehicle speed information is provided to the TCM by the
output revolution sensor. This sensor is located in the
transmission adapter housing. The output revolution
sensor is an electromagnetic pulse pickup type that
generates a speed signal according to the revolution of
the transmission output shaft. As a result, the sensor
sends a sine wave signal (AC) to the TCM, which
converts this sine wave signal (pulse voltage) to a km/h
signal.
Fail-safe control:
The TCM controls fail-safe by detecting output revolution
sensor failure.
Failure detection:
• When not even 1 pulse is input in the output
revolution sensor during the time 4 pulses are input
in the speed meter sensor.
• When the failure criteria is continuously 500 times
from the time ignition is turned ON until it is turned
OFF.
• Detection inhibit condition:
When speed meter sensor revolution is less than 80
rpm.
Contents of control:
At failure detection
• Uses the vehicle speed calculated by speed meter
sensor for shift control
• Keeps the condition of transfer (High/Low judgment)
just before detection until vehicle speed is 0km/h,
and changes shift map to L4 map (3
4UP None) at
vehicle speed 0km/h.
• Use high oil temperature map according to shift map
priority at correct oil temperature control.
• Squat control inhibit
• Up hill and down hill control inhibit
• Reverse lockout control inhibit• Stores the failure information in failure-memory
At failure decision
Executes following items in addition to above control
items at failure detection.
•Blinks "CHECK TRANS" lamp
Conditions of turning "CHECK TRANS" off:
Turns "CHECK TRANS" lamp off when judged 0km/h by
speed meter sensor after more than 1 pulse input in the
output revolution sensor and finished vehicle speed
calculation during the time 4 pulse are input in the speed
meter sensor.
Reversion conditions from fail-safe:
Recovers at the same time as the conditions of turning
“CHECK TRANS” lamp off are satisfied.
Test description:
The following numbers correspond to circled numbers on
the diagnostic char t.
(1) When the vehicle is running, a speed signal is input
from the output revolution sensor to the TCM.
(2) At this test, the continuity of circuit wiring and the
output revolution sensor is checked.
(3) At this test, the continuity of the output revolution
sensor is checked.
Diagnostic aids:
An intermittent may be caused by a poor connection,
rubbed through wire insulation or a wire broken inside
the insulation. Inspect related harness connector for
backed out terminals, improper mating, broken locks,
improperly formed or damaged terminals, poor terminal
to wire connection and damaged harness.

TCM VOLTAGE CHECK
TCM voltage check is done to check for transmission and
transmission control module (TCM) problems which cannot be
detected by self-diagnosis.
Additionally, it serves as a back-up check for self-diagnosis.
Measure the voltage drop and make a continuity test for each
of the sensors, solenoids, and switches.
If the voltage is within the specified range and continuity exists,
that particular area of the TCM and automatic transmission
assembly is normal.
If voltage deviation or lack of continuity is discovered,
disconnect the applicable parts and check each of them
individually.
This will allow you to determine the trouble location (TCM,
automatic transmission unit, or another area of the vehicle).
Inspection Tool
Use a circuit tester to measure voltage and circuit continuity.
Inser t the test probes from the connector wiring side. TCM
terminals are extremely small.
Wrap a piece of thin wire around the probe of tester.
This will make measurement easier.
TCM Voltage Check Procedure
1. Remove the TCM.
2. Turn the ignition switch on. Do not start the engine.
3. Measure the voltage at the terminal. Refer to
the following
table for the specified voltage ranges.

SELECTOR LEVER
INSPECTION
1. Make sure that when the selector lever is shifted from "P" to
"L", a "clicking" can be felt at each shift position. Make sure
that the gear corresponds to that of the position plate
indicator.
2. Check to see if the shifter lever can be shifted as shown.
REMOVAL
Preparation:
Diconnect negative (–) battery cable.
1. Transfer Control Lever Knob
2. Front Console
Disconnect wiring harness connectors.
3. Selector Lever Assembly
1) Disconnect shift lock cable from the selector lever
assembly side.
2) Disconnect wiring harness connectors.
3) Disconnect shift control rod from the selector lever
assembly side.

3) Make sure of proper operation of shift lock through checks
as follows:
a. Selector lever shall not be moved out of "P" position with
ingition key in "Lock" position.
b. Selector lever can be moved out of "P" position with
ignition key in "ON" position only when brake pedal is
depressed.
c. Ignition key can be turned to "LOCK" position only when
selector lever is in "P" position (key can be pulled out).
If (a) and (c) fail, readjust cable. If (b) fails, readjust
connector wiring and brake pedal switch.
