The truck is in mint condition and seems to run fine. But the code reader is reading a code and it say "knock sensor 1 circut high input(bank 1 or single sensor). Is this something I should worry about before buying the vehicle,or is it and easy fix.

The Knock sensor is important, it keeps your pistons from burning up due to detonation(the pinging you hear on hills) it should be an easy fix though. It is a one wire circuit, and could just be disconected, or a bad sensor, and its not hard to replace. I would see if the seller will take care of it for you though....

This code is as important as all the others. This usually a fault with the sensor or the connection to it. The problem is some of these trucks motors have the sensors under the intake plenum which makes it difficult to get at. Nothing money can't fix, but it is a lot of money to fix a simple problem. You decide, get a quote for how much and you will have your answer. Good luck.

probabaly just a bad sensor or un plugged unless you can hear knocking while the motor is running. I would use it to help me negoiate on price. get some kind of a mark down and then replace yourself

you don't have to pay for a repair at all on it,its new,take it back to the dealer and let them fix it,it has a warranty on it ,use it while you can,you,ll miss it when its gone ,and you do have to pay for repairing it,good luck on it.
