Question about 2003 Ford Ranger Regular Cab
Would a defective heat sensor cause my truck to run very rough?
If you are referring to the coolant temp sensor and not the coolant temp switch,then yes,this sensor tells the ecm what temp the engine is at and the ecm delivers the correct amount of fuel to the vehicle.The switch in most cases just sends the signal to the guage or light.
