Smart Coolant Temperature Sensor System Circuit With A Closed Looped Download scientific diagram | smart coolant temperature sensor system circuit with a closed looped loop. from publication: utilization of shape memory alloy (sma) for temperature detection and. If anything in the fan control circuit including the fan itself fails, your modification will not matter. alteration of the coolant temperature sensor output voltage will also alter the fuel map modification for engine temperature. the system will self correct if it stays in closed loop operation.
Smart Coolant Temperature Sensor System Circuit With A Closed Looped The same goes for the p0125 code. if you encounter this code, you might be looking at problems relating to the engine cooling system, particularly the ect sensor or thermostat. below are the possible causes of this trouble code: defective or damaged ect sensor; damaged coolant temperature sensor wiring or connection; low coolant levels; coolant. Depending on year, make, and model, dtc p0125 may have number of causes. here are some of the most common. afr sensor – if the afr sensor is stuck lean, has a faulty heater, or is exposed to an exhaust leak, this can trick the ecm into thinking that the engine has not reached operating temperature. typical afr signal. When it comes to the causes of a p0125 code, it can be something simple, like an ect (engine coolant temperature sensor) plug that got disconnected, or something more serious, like a coolant leak. in the case of a disconnected ect plug, you can reconnect the plug to fix the issue, but the plug or wires connected to the plug can be damaged. Here is a more detailed list of the signs of a bad or failing coolant temperature sensor to look for: 1. check engine light. one of the first signs of all coolant temperature sensor symptoms you will probably notice is that the check engine light will show up on your dashboard. if the computer detects any problem with the sensor’s circuit, it.
