1998 Ford F150 V8 Two Wheel Drive Automatic 171000 miles
Coolant Temp Guage on my 98 f150 2wd 4.6 auto is not working. Checked the sensor, replaced with new one and still nothing. Then checked ohms at sensor and was ok, did not show open circuit.
What volts should I see when checking the opposite end of pigtail that plugs into sensor?
What should I check next?
Getting heat in cabin but truck seems to have a rough idle. Dont think computer is getting correct engine temps.
ecm sensor 25000 ohms and going down as I take measurements. Gauge sensor 2700 ohm and going down as well. Seems like as I hold sensor in hand ohm go down but if I stand sensor upright ohm stay steady? 25k ohms seems kinds high. What do u think?
Will place sensors in pot of hot water and post findings.
