Refer to dtc p0115 (see page es-105).
Monitor description
The resistance of the ect sensor varies in proportion to the actual ect. The ect supplies a constant voltage to the sensor and monitors the signal output voltage of the sensor. The signal voltage output varies according to the changing resistance of the sensor. After the engine is started, the ect is monitored through this signal. If the ect sensor indicates that the engine is not yet warm enough for closed-loop fuel control, despite a specified period of time having elapsed since the engine was started, the ecm interprets this as a malfunction in the sensor or cooling system and sets the dtc.
Example: the ect is 0°c (32°f) at engine start. After about 1 minute running time, the ect sensor still indicates that the engine is not warm enough to begin closed-loop fuel (air-fuel ratio feedback) control. The ecm interprets this as a malfunction in the sensor or cooling system and sets the dtc.

Inspection procedure
Hint:
Hint:
If any dtcs other than p0125 are output, troubleshoot those dtcs first.
Standard value: 80 to 84°c (176 to 183°f)
Hint:
In addition to the above check, confirm that the valve is completely closed when the temperature is below the standard.
Replacement
Replace intake valve guide bush
Heat the cylinder head to 80 to 100°c (176 to
212°f).
Place the cylinder head on wooden blocks.
Using sst and a hammer, tap out the guide bush.
Sst 09201-10000 (09201-01050), 09950-70010
(09951-07100)

Solenoid circuit
Description
This solenoid is turned on in accordance with signals from the skid control
ecu and controls the pressure
on the wheel cylinders to control the braking force.
The solenoid and solenoid relay are built into the abs and traction actuator.
