How do I fix error P0125?
How do I fix trouble code P0125?
- Verify the coolant level.
- Check the thermostat to ensure it is opening properly.
- Inspect the coolant system for leaks and bad wiring.
- Use a voltage meter or infrared thermometer to continue diagnosing the problem.
- Replace faulty components.
What does insufficient coolant temperature mean?
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. The ECM has a predetermined value after you start your vehicle to expect a certain coolant temperature.
What is closed loop fueling?
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 signs of a bad thermostat?
Symptoms of a Failing Car Thermostat
- The temperature gauge reads high and the engine overheats.
- The temperature changes erratically.
- The vehicle’s coolant leaks around the thermostat or under the vehicle.
What causes closed loop fault?
On a two bank vehicle Closed Loop – Fault is when one bank O2 sensor or A/F sensor has a fault. This can be caused by a bad sensor or by one bank being extremely rich or extremely lean. The vehicle will then substitute fuel trim corrections from the “good” bank to the bank it believes has a fault.
What is open-loop vs Closed Loop?
The main difference between an open-loop system and a closed-loop system is that the closed-loop system has the ability to self-correct while the open-loop system doesn’t. Consequently, closed-loop systems are often called feedback control systems while open-loop systems are also known as non-feedback controls.
Is it safe to drive with coolant light on?
So, can you drive safely with your Coolant Pressure Light on? The short answer is that it probably won’t get you killed, but it could mean death to your car engine. An overheated engine can cause incredible damage – failed head gaskets, damaged pistons and valve stems, and distortion or cracks in the cylinder heads.
How much does it cost to replace coolant sensor?
The average price for an engine temperature sensor replacement is between $150 and $193. Labor costs are between $82 and $105 while parts are between $66 and $88.
How can you tell if your thermostat is open?
Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
What does the p0125 code on an engine mean?
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 p0125 code on a Toyota Matrix?
Discovered that a new clue might be that the sputter, under… I’m also getting a recurring P0125 code on a 2003 Toyota Matrix. The engine remains in open loop and the CTS reading from the scanner shows approximately 180 deg F while running.
What kind of check engine light is po125?
I reconnected them… My car developed with check engine light and faulty code was PO125, Toyota agents here replaced ECT sensor, 2 Oxygen sensors, but when I drove it naerly 10 kms, it came up again, Can you help me out to sort the issue….
