Question about 2000 Chevrolet Silverado 1500
Knock engine sensor light on, truck is hesitating/ losing pressure speed on highway. Had fuel pump replaced light has come back on. 2000 Chevy Silverado Shop wants around 450.00 to replace both sensors and said they don't know if that will fix the hesitation/ delay when pressing down on the gas ( especially on the highway). Took it in originally for this problem, that's when they replaced fuel pump, knock sensor came back on within 2 weeks
Did they replace the knock sensor?Check the wire going to the sensor(knock).Look for a bare place hiting up against something ,grounding it out.Make sure the plug to knock sensor is good.And make sure it is making a good connection,Knock sensors also ground a part of the computer to feed back imformation.This connection is a must,the truck will not perform at all,stumble,miss,and carry on.Sometimes even backfire.If they did not replace the knock sensor,replace it with high quality sensor from NAPA,or oem from dealer.This sensor has to be made perfect,no room for inperfection.The knock sensor is easy to replace,they just screw in a hole in the block.When removing the sensors,nothing will come out such as oil or water,this is a dry threaded hole.It is a bell shaped sensor.If you don`t know which sensor is bad,purchase one.replace one,and if there is no change,replace the other side with the old sensor you just took out,it will be a good one.I hope this helps you,Let us know if it does.
