So if the gauge reads low it is likely to be the sensor, if the gauge reads very hot, then it may be something else. But also check the filler cap pressure release. The fan may need about 100C to come on, which will need the system to be pressurised. A dodgy cap can let the water out before it reaches fan temperature. How do I replace the transmission temp sensor? I'm throwing code p1783. Engine: 3.0L. Transmission 6 speed semi automatic. Miles ~115k; Bought @ 53k. Had regular transmission flushes since then. Last one late 2015 @ maybe 70k. Have never replaced engine coolant but most mechanics have told me they don't even do that. peter scott. No, the MAP sensor is a diaphragm with a pressure sensor and temperature sensor behind it. It will not benefit from cleaning. (Unlike the MAF sensor which is in the air intake and does need to be clean to sense air flow correctly.) Your smoke could be due to a split in the hose that comes up from the MAP sensor and connects to the I have a 2007 ford focus 1.6 diesel TDCi. There was a recall last year which the main dealer rewired the cooling fan. This fan is staying on at all times when the engine is running even from cold.

I spoke to a local garage, the owners are ex-Ford main dealers and are pretty switched on. 3lXp. From the haynes manual i can find the following. - radiator fan resistor assembly – which is secured to the top of the fan shroud. - cyclinder head temperature (CHT) sensor.. located on the engine near the spark plugs.

Signs of a faulty sensor in a 2013 Ford Escape 1.6 Common signs of a faulty CHTS might include erratic temperature gauge readings, overheating, poor fuel economy, knock noises from the engine, or the Ford Focus 2012 - 2018 Thermostat Location/ Fault, "High Engine Temperature Stop Safely" Fault. (Copyright 2019) JasonH. I agree a modern car shouldn't have a fluctuating temperature gauge. If it does then the thermostat or temperature sensor are faulty. A faulty thermostat will cause the car to take longer to warm up and therefore increase fuel consumption. Running at low temps can clog up the DPF and soot up the EGR etc.
