Car ECM Trouble Code Solution Not Detected, Pls Help. by izaac23(m): 8:19am On Jul 06 |
I greet you all my people I drive a corolla 2004 model. I had a misfire problem earlier which I later resolve it by servicing the fuel line altogether and it was resolved. After that, my vehicle started having more power than it used to which I thought was a good sign, only for trouble code P0125 (insufficient coolant temperature for close loop fuel control) appeared. I have tested my ECT sensor alias cold switch, confirm that my thermostat is still working, I don't know how to test the O2 sensor, the electricians at my location are not digitally inclined. This has decreased my fuel economy by over 30%. The quantity of fuel that takes me for 100 miles distance is now taking me for 70 miles. Pls gurus in the house, I need your help, wat else can I do to this car in this cheap fuel era, who knows wat trigger this code in a corolla? Help me pls. |

If you drive the car long enough, maybe 15 minutes on the highway, and plug the scan tool, your coolant temperature should be reading about 190. After driving a while is your fan running? that switch controls the fan If your sensor is covered with rust and it is interfering with reading, or bad wiring. Solution is to drive and when the car is hot and fan is running you use a thermostat to confirm the temperature is same as the reading of the engine coolant |

02 sensors maybe good look at the exhaust net,check for any charcoal black stain against the body of the net,a leaking exhaust flex net throws a false code to 02 sensors |

sultaan: When the temperature is hot, the fan starts and stops when it deems fit. My OBD11 showed that the temperature is up to 190 after warming it for a while and the temperature indicated at the instrument cluster shows the temp rising to half of the measurement in less than 15mins of warming it sir |

Nomerci: It has always been like that from when I bought it 5 years ago, and it had no issue I diagnosed code P0125 as shown above on my first msg sir |
