Hi, hoping for some help. My TL have close to 120K and a check engine light came on due to an error code of p0118. From what I have read it seems like I need to replace the sensor to have this fixed. Can anyone tell me for sure if that is what I need to do or could this code be due to a different problem. If all I need is the new sensor, can someone tell me what this sensor is called and also give me some suggestion on how to change it, I am hoping to avoid going the dealership for this.

codes are clues to the problem- not a diagnosis themself--
have to put the clues together to find the real issue
