DTC P1217 ENGINE OVER TEMPERATURE
*2: Engine running at 3,000 rpm for 10 minutes.
*3: Drive at 90 km/h (55 MPH) for 30 minutes and then let idle for 10 minutes.
*4: After 60 minutes of cool down time.
For more information, refer to “Overheating Cause Analysis”, LC-20.
Component Inspection

COOLING FAN RELAY-1
1.
Apply 12V direct current between relay terminals 1 and 2.
2.
Check continuity between relay terminals 3 and 5, 6 and 7.
3.
If NG, replace cooling fan relay.
COOLING FAN MOTORS-1 AND -2
1.
Disconnect cooling fan motor harness connectors.
2.
Supply cooling fan motor terminals with battery voltage and
check operation.
Cooling fan motor should operate.
If NG, replace cooling fan motor.

DTC P1223, P1224 TP SENSOR
PFP:16119
Component Description
EBS00R0C
Electric Throttle Control Actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement.
The throttle position sensor has the two sensors. These sensors are
a kind of potentiometers which transform the throttle valve position
into output voltage, and emit the voltage signal to the ECM. In addi-
tion, these sensors detect the opening and closing speed of the
throttle valve and feed the voltage signals to the ECM. The ECM
judges the current opening angle of the throttle valve from these sig-
nals and the ECM controls the throttle control motor to make the
throttle valve opening angle properly in response to driving condi-
tion.
CONSULT-II Reference Value in Data Monitor Mode
EBS00R0D
Specification data are reference values.
*: Throttle position sensor 2 signal is converted by ECM internally. Thus, it differs from ECM terminal voltage signal.
On Board Diagnosis Logic
EBS00R0E
These self-diagnoses have the one trip detection logic.
FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MI lights up.
DTC Confirmation Procedure
EBS00R0F
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10V at idle.

Trouble diagnosis name
DTC detecting condition
Possible cause
P1223
1223
Throttle position sensor 2
circuit low input
An excessively low voltage from the TP sensor 2
is sent to ECM.
●
Harness or connectors
(The TP sensor 2 circuit is open or
shorted.)
●
Electric throttle control actuator
(TP sensor 2)
P1224
1224
Throttle position sensor 2
circuit high input
An excessively high voltage from the TP sensor 2
is sent to ECM.
Engine operation condition in fail-safe mode
The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle position to be within +10
degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal condition.
So, the acceleration will be poor.

DTC P1223, P1224 TP SENSOR
WITH CONSULT-II
1.
Turn ignition switch “ON”.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Start engine and let it idle for 1 second.
4.
If DTC is detected, go to
EC-794, "Diagnostic Procedure"
.
WITHOUT CONSULT-II
1.
Start engine and let it idle for 1 second.
2.
Turn ignition switch “OFF”, wait at least 10 seconds and then turn “ON”.
3.
Perform “Diagnostic Test Mode II (Self-diagnostic results)” with ECM.
4.
If DTC is detected, go to
EC-796, "Component Inspection"
.
