What does closed loop fuel control mean?
In a nutshell, closed loop is where the engine operates with a feedback loop. A sensor closes the loop. The sensor in question is a lambda sensor, also known as an oxygen sensor or air/fuel ratio mixture sensor. In closed loop mode, the engine listens to the lambda sensor to adjust fuel/air mixture.
What are examples of closed loop systems?
Given below are 10 examples of closed loop control systems.
- Thermostat Heater.
- Sunseeker solar system.
- Voltage stabilizer.
- Missile Launcher.
- Auto Engine.
- Inverter AC.
- Automatic toaster.
- Turbine Water Control System at power Station.
What does insufficient coolant temperature for closed loop fuel control mean?
Insufficient Coolant Temperature For Closed Loop Fuel Control What the P0125 code means P0125 is the OBD-II generic code for the engine computer, or Engine Control Module (ECM), not detecting enough heat in the cooling system before the fuel management system can take control.
What is the diagnostic code for insufficient coolant?
P0125 OBD-II Trouble Code: Insufficient Coolant Temperature for Closed Loop Fuel Control. Cost of diagnosing the P0125 code. P0125 is a diagnostic trouble code (DTC) for “Insufficient Coolant Temperature for Closed Loop Fuel Control”.
What is the DTC for insufficient coolant temperature?
The ECM will set a diagnostic trouble code (DTC) in memory and may or may not command the malfunction indicator lamp (MIL) to illuminate. DTC P0125 is defined as “Insufficient Coolant Temperature for Closed Loop Fuel Control.” What are the common causes of code P0125 ?
What happens if there is insufficient coolant in the engine?
If there is insufficient coolant in the system, the engine may not warm properly. If the ECT is not in contact with the coolant, it will not read the temperature. Similarly, if there is a problem with the ECT sensor or circuit, the ECM may not receive a true indication of the engine coolant temperature.
