I have been to a local shop for the same problem on my 2003 silverado. It is a worn out sensor, it will have to be replaced. In my case I replaced the seat and seatbelt catch and all the sensors from a wreaked 04 silverado.
It's the sensor after the cat on the passenger side
It is screewed into the passenger side of the engine, just in front of the starter.
how do you change the knock sensor in a 2003 Chevy silverado 5.3
It is screewed into the side of the engine block on the passenger side just in front of the starter.
Bank 2 is the side of the engine where the #2 spark plug is. On my 99 Silverado it's on the passenger side.
That would be the passenger side of the engine and it will be the first oxygen sensor that's screewed into the exhaust pipe on that side.
were is the cam shaft sensor
The 1995 Chevy Silverado coolant sensor is located on the front of the engine. The coolant sensor will be a few inches above the thermostat housing.
It is mounted in the passenger side of the engine block right behind the starter. You will have to remove the starter to get to it.
NO it does not.
unscrew it
Behind the starter.
