P0118 help

[Grettski03]

i have a 1999 SE 4 litre. my dash is throwing me a P0118 iv read online people saying there is only one coolant sensor but others say some older models can have two of these sensors? can anyone tell me if this is true? and is there a part number for this sensor from a reliable retailer online, Iv bought too many parts claiming to fit my TJ that didnt work out.

You have one. Changing the sensor will more than likely fix it (a quick resistance check would confirm) unless there's a wiring issue or a super rare PCM issue. Idk about fitment or finding a reputable dealer. If I can't find OEM, I just use whatever the stupid parts houses carry. It's too easy of a part to change to sweat too awful much.
