Troubleshooting Power Loss and Spark Issues in a 2008 Chevy Aveo

Experiencing a sudden loss of power in your 2008 Chevy Aveo can be frustrating, especially when you've already checked some common issues. In your case, the fact that the vehicle cranks but does not start indicates that the engine is not receiving a spark. Let’s break down the troubleshooting steps based on the diagnostic trouble codes (DTCs) you retrieved and provide a comprehensive approach to resolve this issue.

Understanding the Diagnostic Trouble Codes (DTCs)

You mentioned several DTCs that were retrieved from your vehicle's scanner:

• P0031: H02S Heater Control Circuit Low (Bank 1, Sensor 1)
• P0351: Ignition Coil A Primary/Secondary Circuit
• P0352: Ignition Coil B Primary/Secondary Circuit
• P2106: Throttle Actuator Control System – Forced Limited Power
• P2110: Throttle Actuator Control System – Forced Limited RPM
• P0137: O2 Circuit Low Voltage (Bank 1, Sensor 2)
• P0458: Evaporative Emission System Purge Control Valve Circuit Low

While all these codes provide insight into potential issues, the ignition coil circuit codes (P0351 and P0352) are particularly relevant as they directly indicate a problem with the ignition system, which is crucial for generating spark.
