• Electric throttle control actuator

(TP sensor 2)

P0123

TP SEN 2/CIRC-B1
(Throttle position sensor 
2 circuit high input)

An excessively high voltage from the TP sensor 
2 is sent to ECM.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

>> GO TO 2.

2.

CHECK ENGINE COOLANT TEMPERATURE SENSOR FUNCTION

With CONSULT

1. Turn ignition switch ON.

2. Select “DATA MONITOR” mode of “ENGINE” using CONSULT.

3. Check that “COOLAN TEMP/S” is above 10

°C (50°F).

With GST

Follow the procedure “With CONSULT” above.
Is it above 5

°C (41°F)?

YES

>> INSPECTION END

NO

>> GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

1. Start engine and run it for 65 minutes at idle speed.

2. Check 1st tip DTC.

If “COOLAN TEMP/S” indication increases to more than 10

°C (50°F) within 65 minutes, stop engine

because the test result will be OK.

CAUTION:

Be careful not to overheat engine.

With GST

Follow the procedure “With CONSULT” above.
Is 1st trip DTC detected?

YES

EC-257, "Diagnosis Procedure"

.

NO

>> INSPECTION END

DTC No.

(Trouble diagnosis con-

tent)

DTC detecting condition

Possible cause

P0125

ECT SENSOR
(Insufficient engine coolant 
temperature for closed 
loop fuel control)

• Voltage sent to ECM from the sensor is not 

practical, even when some time has passed 
after starting the engine.

• Engine coolant temperature is insufficient for 

closed loop fuel control.

• Harness or connectors

(High resistance in the circuit)

• Engine coolant temperature sensor
