P06B2 2016 Chevrolet Silverado Code - Sensor Supply Voltage Circuit High Voltage
Quick Answer
The P06B2 diagnostic trouble code (DTC) indicates that the Engine Control Module (ECM) has detected a high voltage condition in the sensor supply voltage circuit. Common causes include Faulty Wiring or Connectors: Damaged or corroded wiring in the sensor supply voltage circuit can lead to high voltage readings, Defective Voltage Regulator: A malfunctioning voltage regulator may allow excessive voltage to flow into the sensor circuit, Faulty Sensors: Sensors that are internally shorted can draw too much voltage, triggering the P06B2 code. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P06B2 2016 Chevrolet Silverado Description
The P06B2 diagnostic trouble code (DTC) indicates that the Engine Control Module (ECM) has detected a high voltage condition in the sensor supply voltage circuit. This circuit is responsible for providing power to various sensors throughout the vehicle, including those related to engine performance, emissions, and other critical systems. When the voltage exceeds the expected range, it can lead to erratic sensor readings, causing the ECM to make incorrect adjustments to fuel delivery, ignition timing, and other vital functions.
Common Causes of P06B2 2016 Chevrolet Silverado
- Faulty Wiring or Connectors: Damaged or corroded wiring in the sensor supply voltage circuit can lead to high voltage readings.
- Defective Voltage Regulator: A malfunctioning voltage regulator may allow excessive voltage to flow into the sensor circuit.
- Faulty Sensors: Sensors that are internally shorted can draw too much voltage, triggering the P06B2 code.
- ECM Malfunction: A failing ECM may misinterpret voltage levels, leading to erroneous readings and triggering the code.
- Aftermarket Modifications: Non-OEM parts or modifications to the electrical system can inadvertently cause high voltage issues.
Symptoms of P06B2 2016 Chevrolet Silverado
- Check Engine Light: The most immediate symptom is the illumination of the check engine light on the dashboard.
- Poor Engine Performance: Drivers may notice a decrease in power, acceleration, or overall engine responsiveness.
- Increased Fuel Consumption: Erroneous sensor readings can lead to improper fuel-air mixture, resulting in decreased fuel efficiency.
- Rough Idling: The engine may idle roughly or inconsistently due to incorrect sensor data affecting engine timing and fuel delivery.
- Emissions Issues: The vehicle may fail emissions tests due to improper readings from sensors that monitor exhaust gases.
How to Fix P06B2 2016 Chevrolet Silverado
- Diagnostic Scan: Begin with a thorough diagnostic scan to confirm the P06B2 code and check for any additional codes that may provide further insight.
- Visual Inspection: Inspect the wiring and connectors associated with the sensor supply voltage circuit for signs of damage, corrosion, or loose connections.
- Test Voltage Levels: Use a multimeter to measure the voltage levels in the circuit. Compare the readings to manufacturer specifications to identify any discrepancies.
- Replace Faulty Components: If any damaged wiring, connectors, or sensors are found, replace them as necessary. If the voltage regulator is faulty, it should also be replaced.
- ECM Reprogramming or Replacement: If the ECM is determined to be the source of the problem, it may need to be reprogrammed or replaced.
Cost to Fix P06B2 2016 Chevrolet Silverado
The cost of repairing the P06B2 code can vary widely based on the specific diagnosis and repairs needed. On average, you might expect to pay between $200 and $800 for repairs, which could include parts and labor. For instance, replacing a faulty sensor might cost around $100 to $300, while more extensive repairs involving wiring or the ECM could escalate costs significantly. Labor rates typically range from $80 to $150 per hour, depending on the shop's location and reputation. In metropolitan areas or dealerships, rates may be higher, while independent shops often offer more competitive pricing. It is advisable to consult local repair shops for a more precise estimate based on your specific situation.
