DTC P0125: Insufficient Coolant Temperature for Closed Loop Fuel Control (FROM 12/2010): Description
WARNING: This page is about a different car, the 2011 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
A thermistor, whose resistance value varies according to the engine coolant temperature, is built into the engine coolant temperature sensor.
The structure of the sensor and its connection to the ECM are similar to those of the intake air temperature sensor.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0125 | Engine coolant temperature (ECT) does not reach closed-loop enabling temperature for 20 minutes (this period varies with ECT when engine start) (2 trip detection logic) |
