So i changed the oil on my truck and it didnt fix the p0198 code... rubbish! So now i am thinking about replacing the sensor. i googled Oil temp sensor for rough prices and i didnt get anything... ? so i called autozone he didnt see that part anywhere. Then i called Ford, the parts guy said its called "coolant temp sensor" does this sound right? If it was called that why did the code say OIL TEMP not COOLANT temp? anyone else replace this? if so where is it? and how expensive is it? Thank You in advanced

Now i called O'Reily's and they said ti was the fuel rail pressure. then why is it saying OIL TEMP SENSOR!!!!!!!? ugh so again i turned to google. The code pulled up the Oil Temp Sensor and that there may be an open circuit. what do i do. i feel like i can't trust anyone here!!! Ford wants $90 to just diagnose it!
