No

1

Was “A/T System Check” performed?

Go to Step 2.

Go to “A/T System 
Check”.

2

Check input shaft speed sensor circuit
1) Disconnect TCM connectors with ignition switch OFF.
2) Check for proper connection to input shaft speed sensor 

at “E93-5” and “E93-14” terminals.

3) If OK, check resistance of sensor circuit.

Resistance of input shaft speed sensor circuit
Between terminals “E93-5” and “E93-14” of 
disconnected harness side TCM connector: 560 – 
680 

Ω at 20 °C (68 °F)

Between terminals “E93-14” of disconnected 
harness side TCM connector and ground: No 
continuity

Are check results satisfactory?

Go to Step 4.

Go to Step 3.

3

Inspection output shaft speed sensor
Inspect input shaft speed sensor referring to “Output Shaft 
Speed Sensor Inspection”.

Is check result satisfactory?

Output shaft speed 
sensor circuit is 
malfunction.

Go to Step 4.

4

Check visually Output shaft speed sensor and sensor 
rotor using mirror for following
• No damage
• No foreign material attached
• Correct installation

Are they in good condition?

Intermittent trouble. 
Check for intermittent 
trouble referring to 
“Intermittent and Poor 
Connection Inspection 
in Section 00”.

Clean, repair or replace.

solenoid to turn ON. (2 driving cycle detection logic)

• Mechanical malfunction of TCC pressure control 

solenoid valve.

• Malfunction of valve body assembly.
• Fluid passage clogged or leaking.
• Torque converter clutch malfunction.

DTC P0742:
When driving vehicle in “D” range, difference in revolution

DTC Confirmation Procedure

WARNING

!

 

• When performing a road test, select a place where there is no traffic or possibility of a traffic 

accident and be very careful during testing to avoid occurrence of an accident.

• Road test should be carried out with 2 persons, a driver and tester, on a level road.

 

1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTCs in TCM and ECM memories by using scan tool.
3) Start engine and warm it up to normal operating temperature.
4) Shift select lever to “N” and “D” range for each 10 seconds.
5) Drive vehicle with 4th in “D” range and lock-up ON for 20 seconds or longer referring to “Automatic Gear Shift 

Table”.

6) Drive vehicle with 2nd or 3rd gear in “D” range, 15 – 20% throttle opening and at vehicle speed of 40 km/h (25 

mile/h).

7) Stop vehicle and turn ignition switch OFF.
8) Repeat Step 3) to 6) one time.
9) Stop vehicle.

10) Check DTC, pending DTC and freeze-frame data.
