Description
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.
Open in abs solenoid relay circuit
Description
The solenoid relay supplies power to the abs solenoid and trc solenoid.
After the ignition switch is turned on, the vehicle speed has reached 6 km/h (4
mph) and the solenoid is
determined to be normal by the initial check self-diagnosis, the relay switches
on. If any open or ...
Oxygen (a/f) sensor pumping current circuit
Description
Refer to dtc p2195 (see page es-292).
Monitor description
The air-fuel ratio (a/f) sensor varies its output voltage in proportion to
the air-fuel ratio. If the a/f sensor
impedance (alternating current resistance) or output voltage deviates greatly
from the standard range ...
