If the P0073 code does return, we will need to test the AAT sensor and its associated circuits. Typically, there are 2 wires at the AAT sensor. With the ignition switch off, disconnect the harness going to the AAT sensor. Turn the ignition switch on. With a scan tool accessing PCM data (provided that is the module receiving the AAT sensor input Location Of Coolant Temp Sensor. this question may have been asked before, sorry. where is the coolant temperature sensor located on a 2004 2.0 tdci mondeo (aka the cylinder head temp sensor, i think) and what would be the best way to go about replacing it myself as opposed to taking it to a garage. riikomi. 758 posts · Joined 2012. #2 · May 25, 2016. The sensor is located in the dome close to the windshield in the same unit which houses the sunlight sensor. In newer models (2010?->), the sensor is on the under side of the steering column. Gloves. 1. With the engine and coolant entirely cooled down, disconnect the battery. This is recommended for any electrical procedure. 2. Remove any plastic engine covers. Depending on the engine, you may have to remove part of the plastic air intake tubing. 3. Locate the coolant temp sensor. 77 - 80 with no thermostat sounds wrong. These engines run cool and shouldn't. really move off the cold zone with no thermostat. I think you have another issue. The thermostat you have should start to open at. 88 degrees C and be fully open at 102 degrees C. The area you need to look at is here -. Your looking at the area where the coil wires go to. Then if you feel under it you can feel the wiring which goes to the temperature sensor -. If it helps the rear of the sensor will face towards the car. Be aware thought that there are two types of fittings. One sensor screws in and the other is held in tgiG. If you have fog lights there will be a set of wires running to the drivers side fog light. There will be another wire running from the front of the body to the inside rear of the bumper. Follow this wire and the temperature sensor will be at the end of it inside the bumper. The sensor is held in place by a sprung piece of metal. Location Of Coolant Temp Sensor. this question may have been asked before, sorry. where is the coolant temperature sensor located on a 2004 2.0 tdci mondeo (aka the cylinder head temp sensor, i think) and what would be the best way to go about replacing it myself as opposed to taking it to a garage. But in my case the interior temperature sensor seems broken, because it shows 103 °C. Furthermore, my ford focus mk3 1.0 ecoboost is having P2188 code. The mechanic said that the faulty interior temparture creates the failure because interior temperature influences the ECU as well. In this video we go into detail of the code P2479: Limp ModePlease contact us on 01274 640028 for more enquiries If you're watching this I'm guessing you've come across issues where your ambient temperature reading was showing 0°F or -40°F and your A/C air conditioning O2 sensors comoly have 5 wires. 2 for a pre heater (this warms the sensor up to ge tit ot operating temperature). Once the ca ris wormed up the sensor may actually be working dueott the heat form the exhaust. The other 2 wires are for the sensor. I would expect to find an open circuit between the 2 heater wires.
