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">.
| STEP | CHECK | YES | NO |
1.CHECK ENGINE COOLANT.
Check the following items:
• Amount of engine coolant
• Engine coolant freeze
• Contamination of engine coolant
Is the check result OK?

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.
2. COMPONENT DESCRIPTION
(A) | Resistance value (k?) | (B) | Temperature °C (°F) | ||
(1) | Connector | (2) | Thermistor element |
3. EXECUTION CONDITION
Secondary parameters | Execution condition |
Battery voltage | ≥ 10.9 V |
Engine speed | ≥ 500 rpm |
Engine coolant temperature at engine start | < −15 °C (5 °F) |
4. GENERAL DRIVING CYCLE
Perform the diagnosis only once after starting the engine from cold condition.
5. DIAGNOSTIC METHOD
If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.
Malfunction Criteria | Threshold Value |
Engine coolant temperature | < −15 °C (5 °F) |
Elapsed time after starting the engine | |
(At the time of (The smaller value of either Engine coolant temperature or Intake air temperature at engine start) ≥ −23.3°C (−9.9°F)) | ≥ 120 s |
or | |
(At the time of (The smaller value of either Engine coolant temperature or Intake air temperature at engine start) < −23.3°C (−9.9°F)) | ≥ 300 s |
Time needed for diagnosis: Less than 1 second
Malfunction indicator light illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
