Toyota Tundra. Manual — part 2805

If a circuit related to the ATF temperature sensor becomes open, P0713 is immediately set (in 0.5
seconds). When P0713 is set, P0711 cannot be detected. It is not necessary to inspect the circuit
when P0711 is set.

1. INSPECT NO. 1 TRANSMISSION WIRE (NO. 1 ATF TEMPERATURE SENSOR)

a. Disconnect the D63 No. 1 transmission wire connector.

b. Measure the resistance according to the value (s) in the table below.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION TABLE

HINT:

If the resistance is out of the specified range at one of the ATF temperatures shown in the table
below, the driveability of the vehicle may decrease.

DESCRIPTION

This sensor detects the rotation speed of the turbine which shows the input revolution of the transmission. By
comparing the input turbine speed signal NT with the counter gear speed sensor signal SP2, the ECM detects
the shift timing of the gears and appropriately controls the engine torque and hydraulic pressure according to
various conditions. As a result, the gears shift smoothly.

MONITOR DESCRIPTION

This DTC indicates that a pulse is not output from the speed sensor NT (turbine (input) speed sensor) or is
output only a little. The NT terminal of the ECM detects the pulse signal from the speed sensor NT (input
RPM). The ECM outputs a gear shift signal comparing the input speed sensor NT with the output speed sensor
SP2.

While the vehicle is operating in 4th, 5th or 6th gear in the shift position of D, if the input shaft revolution is
less than 300 RPM*1 although the output shaft revolution is 1000 RPM or more*2, the ECM detects the
trouble, illuminates the MIL and stores the DTC.

HINT:



*1: A pulse is not output or is irregularly output.



*2: The vehicle speed is approximately 50 km/h (30 MPH) or more.
