P1919
Engine coolant
temperature signal error
•
If the engine coolant temperature
signal from the PCM, which is
transmitted using the CAN
communication, is invalid and the
condition has continued for
500 ms or
more .
•
inhibits TCC, slip control
•
Fixes the engine coolant
temperature signal at
80
°
C {176
°
F}
Enabled
P2544
Engine torque signal error
(invalid signal)
•
If the engine torque signal or engine
torque-loss signal from the PCM,
which is transmitted using the CAN
communication, is invalid and the
condition has continued for
500 ms or
more .
•
Emergency mode 1
•
Fixes the engine torque
signal at the maximum Enabled
P2757
Torque converter clutch
(TCC) (stuck off)
•
Difference of 100 rpm or more
between engine and counter drive
gear (output) speeds is detected
when driving in D range, engine
speed is
less than 400 rpm , TCC
control solenoid is on, and ATF
temperature is
20
°
C {68
°
F} .
•
Inhibits self learning
control

Inhibits TCC control
•
Inhibits TCC, slip control
Disabled
P2758
Torque converter clutch
(TCC) (stuck on)
•
Difference of less than 30 rpm
between engine and turbine speeds is
detected when driving in D range,
engine speed is
within 1,000—3,000
rpm , TCC control solenoid is off, and
ATF temperature is 20

C {68
°
F} .
•
Inhibits self learning
control
•
Inhibits TCC control
•
Inhibits TCC, slip control
•
Inhibits driver adaptive
shift control
•
Engine stall avoidance
control (Engine braking is
applied in 1GR when

Emergency mode 1 Disabled
P2763
TCC control solenoid
circuit malfunction (short to
power)
•
Short circuit in TCC control solenoid
signal system (when TCM monitors
solenoid output voltage, voltage that
differs from signal output by CPU in
TCM is detected).

Disabled
P2764
TCC control solenoid
circuit malfunction (short to
ground/open circuit)
•
Open or short circuit in TCC control
solenoid signal system (when TCM
monitors solenoid output voltage,
voltage that differs from signal output
by CPU in TCM is detected).
