When DTC P1104 is on display, check engine cooling sys-
tem.
CAUTION:
After repair or replacement of faulty parts, conduct
CLEAR MEMORY and INSPECTION MODES.
[T3D0] and [T3E0].>
NOTE:
If the vehicle, with the engine idling, is placed very close to
a wall or another vehicle, preventing normal cooling
function, the OBD system may detect malfunction.

—THROTTLE POSITION SENSOR CIRCUIT
MALFUNCTION FOR AUTOMATIC
TRANSMISSION (ATTH)—
DESCRIPTION:
The throttle position sensor provides electrical signals
corresponding to the throttle opening. The throttle opening
and accelerator depression speed are detected by this
throttle position sensor output.
Detects throttle opening and determines shift point, line
pressure and lockup vehicle speed according to engine
load.
SOR CIRCUIT MALFUNCTION—[T11G0]”.>
DTC DETECTING CONDITION:
Two consecutive trips with fault
TROUBLE SYMPTOM:
Shift point too high or too low; engine brake not effected
in“3”range; excessive shift shock; excessive tight corner
“braking”

1.Check harness connector between TCM and
throttle position sensor.
2.Check throttle position sensor.
3.Check input signal for TCM.
4.Check power supply to throttle position
sensor.
CAUTION:
After repair or replacement of faulty parts, conduct
CLEAR MEMORY and INSPECTION MODES.

DESCRIPTION:
Detects operation of cruise control, and expands“4th”
operating range.
DTC DETECTING CONDITION:
Two consecutive trips with fault
1.Check harness connector between TCM and
CCM.

1.CHECK HARNESS CONNECTOR BETWEEN
TCM AND CCM.
1) Turn ignition switch to OFF.
2) Disconnect connectors from TCM and CCM.
3) Measure resistance of harness connector between
TCM and CCM.
: Connector & terminal
(B56) No. 3—(B94) No. 3 / 10Ω, or less
: Repair open circuit of harness between TCM con-
nector and CCM connector.
: Go to next step.
OBD0515A
4) Measure resistance of harness connector between
TCM and body.
: Connector & terminal
(B56) No. 3—Body / 1 MΩ, or more
: Repair short circuit of harness between TCM con-
nector and CCM connector.
: Go to step 2.

CHECK INPUT SIGNAL FOR TCM.
1) Connect connector to TCM and CCM.
2) Lift-up the vehicle or set the vehicle on free rollers.
CAUTION:
On AWD models, raise all wheels off ground.
3) Start the engine.
4) Cruise control main switch to ON.
5) TCS OFF switch to ON. (with TCS models only)
6) Move selector lever to“D”and slowly increase vehicle
speed to 50 km/h (31 MPH).
7) Cruise control set switch to ON.
8) Measure voltage between TCM and body.
: Connector & terminal
(B56) No. 3—Body / 1 V, or less
: Check cruise control set circuit.
[T7A0].>
: Go to next.
: Is there poor contact in TCM connector?
: Repair poor contact in TCM connector.
: Replace TCM with a new one.
