Can A Bad Coolant Temp Sensor Cause Rough Idle. After that, the idle is rough and there is a severe loss of power. The short answer is no.
Hey i have 2006 bmw e90 i replaced my water pump, thermostat, radiator, condenser, i did a bleed the system, fan and cooling seems to be working, i dont get the yellow. A4 2.0 tdi 170 rough idle and white smoke when warming up. A check engine light illuminating.
Possible Problems That Can Cause A Car To Overheat Range From A Cooling Hose Leak, Faulty Cooling Fan, Broken Water Pump, Or Bad Temperature Sensor.
The coolant temperature sensor can fail and transmit cold signals to the computer. A bad coolant temperature sensor can cause a car to overheat and potentially catch on fire. This sensor is in charge of signaling the car’s internal computer, the electronic control unit, when the engine's coolant liquid is running too cold or too hot, telling the computer to deliver either more or less fuel to the engine.
When The Engine Is Cold, There Is More Fuel Delivered;
Yes.let's pretend it's warm out in the 60° area.but the sensor in the engine thinks its 34° when you start that car, the computer will run rich on fuel to warm it up even thou naturally it's already warm all ready and only needs a short time to warm up, while in rich mode, its. The coolant temperature sensor is located on the water pump and transmits a signal to the ecu. The issue will eventually worsen as the pulley continues to wear not as big of a job as the timing belt but big enough , plug wires injectors, timing belt, serptine belt, tensioner, fuel filter,temp sensor, cooling fan switch, but as soon i can't see why one would replace a 62,000 mile 2001 r/t timing belt tensioner that was working properly there should be a gentle arm motion as.
