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.
Removal
Discharge refrigerant from
refrigeration system (see page ac-172)
Disconnect cable from negative battery
terminal
Caution:
Wait at least 90 seconds after disconnecting the
cable from the negative (-) battery terminal to
prevent airbag and seat belt pretensioner activation.
Remove ...
Brake switch "b" circuit high
Description
The purpose of this circuit is to prevent the engine from stalling while
driving in the lock-up condition when
the brakes are suddenly applied.
When the brake pedal is depressed, this switch sends a signal to the ecm. Then
the ecm cancels the
operation of the lock-up clutch ...
Installation
Hint:
Use the same procedures for the rh side and lh side.
The procedures listed below are for the lh side.
Install front door belt moulding
assembly lh
Attach the claws to install the belt moulding.
Hint:
Confirm that the moulding is firmly installed.
Install outer r ...
