Coolant temp sensor and coolant temp sender?

[Bonecollector]

Do these trucks have a coolant temp sensor and the coolant temp sender like my 94? I think I'm having issues with the coolant temp sensor, sometimes it will show up in my cluster saying reduced engine power and I can't do better than 50 km/hr

whens the last time you changed your coolant? keep an eye on the temp. could just be getting too hot....my truck did that last summer, especially when its really warm out. changed my coolant when i did my water pump in november and havent had any problems since.

I think the last time i looked up rep it was due to a throttle body wire was broken inside the wire casing check that to maybe that will fix the rep

Hmmm owners manual tells me that code means engine is trying to protect itself from damage, i probably do need to change my coolant tho...

Also, it doesn't happen all the time, it'll happen a couple of times then not happen for a while, that makes me think it's an electrical issue/sensor that's dying

Guess I'll have to check grounds for my computer if it happens again
