Code P0697 2016 Chevrolet Silverado Description
The P0697 code in a 2016 Chevrolet Silverado refers to a "5 Volt Reference 3 Circuit" issue. In modern vehicles, the Engine Control Module (ECM) provides a 5-volt reference signal to various sensors and components throughout the vehicle. This reference voltage is used by these sensors to provide feedback to the ECM, helping it to accurately control engine performance, emissions, and other critical functions. When the ECM detects that the voltage in the 5 Volt Reference 3 Circuit is outside of the normal range, it triggers the P0697 diagnostic trouble code (DTC).
Common Causes of P0697 2016 Chevrolet Silverado
- Wiring harness issues
- Damaged connectors
- Faulty ECM
- Short circuit in the 5-volt reference circuit
- Corrosion in the electrical connections
Symptoms of P0697 2016 Chevrolet Silverado
- Engine misfires
- Rough idling
- Stalling
- Poor fuel efficiency
- Check Engine Light illuminated
