**_I Don’t Know A 97 Sonoma 4.3L From A Hay Bale, But According To My Info:  
On Models Equipped With HVS (High Voltage Switch) Systems Or With A DI (Distributor Ignition System) The Camshft Position Sensor Is Located Inside The Distributor Assembly._**

Disconnect the negative battery cable.  
Remove cap and rotor.  
Unplug the sensor connector.  
Remove sensor screws.

That code often turns on the CEL in cars / trucks and there are lots of causes. Professional diagnosis to pinpoint the exact cause(s) could be less expensive than replacing engine parts, one or two at a time. Although, any items like plugs, wires, etcetera, that need replacing because they’re due (mileage, age) won’t hurt.

A compression check would be helpful as a starting point.

I don’t think a bad cam sensor will cause a miss, but it will give you lousy economy and performance, and if it is intermittently failing, it may cause the car to jerk or buck.
