I have a 2007 Chevy Silverado 1500 5.3L (new body style)
code came up for P0335 (crankshaft sensor circuit)
We replaced the sensor and upon inspection, we needed to replace other parts (related or unrelated)
-Camshaft sensor
-Plugs and Wires
-Fuel Pump
-Timing Chain
The issue now is the check engine light still comes on, along with the stabilitrak/traction control off light.
The main problem is that when the stabilitrak/traction control lights come on it causes issues with the tach and the meter will either stop working and or it causes rough shifting from 1-2 gear. I will sometimes lose power when driving, or the rpm will randomly drop below 1000 and get stuck there for a few seconds and then spike back up. We've had the engine completely shut off while driving.
Every time the lights come on the symptoms are a bit different each time but usually some mix of the things listed above. Sometimes the lights will come on 5 minutes into a drive sometimes I can drive 5 days no issues
