ENGINE (DIAGNOSTICS)(H4DO) > Diagnostic Procedure with Diagnostic Trouble Code (DTC)

DTC P0125 INSUFFICIENT COOLANT TEMPERATURE FOR CLOSED LOOP FUEL CONTROL

DTC detecting condition:

Detected when two consecutive driving cycles with fault occur.

Trouble symptom:

Engine does not return to idle.

CAUTION:

After servicing or replacing faulty parts, perform Clear Memory Mode Clear Memory Mode > OPERATION">, and Inspection Mode Inspection Mode > PROCEDURE">.

STEPCHECKYESNO

1.CHECK ENGINE COOLANT.

Check the following items:

Amount of engine coolant

Engine coolant freeze

Contamination of engine coolant

Is the check result OK?

Fill or replace the engine coolant. Engine Coolant > REPLACEMENT">

2.CHECK THERMOSTAT.

Does the thermostat remain opened?

Replace the thermostat. Thermostat">

Replace the engine coolant temperature sensor. Engine Coolant Temperature Sensor">

1. OUTLINE OF DIAGNOSIS

Detect the malfunction of engine coolant temperature output property.

Judge as NG when engine coolant temperature does not rise to the specified value after predetermined time has elapsed since engine start.
