Code P106B Toyota Description
The P106B diagnostic trouble code (DTC) for Toyota vehicles specifically refers to a problem with the Evaporative Emission System Pressure Sensor and Secondary Air Injection Pressure Sensor correlation. This code indicates that there is a discrepancy between the readings from these two sensors, which are crucial components of the vehicle's emissions control system. The Evaporative Emission System (EVAP) is responsible for capturing and storing fuel vapors from the fuel tank to prevent them from being released into the atmosphere. The Secondary Air Injection system injects fresh air into the exhaust system to help reduce emissions.
Common Causes of P106B Toyota
- Faulty Evaporative Emission System Pressure Sensor
- Faulty Secondary Air Injection Pressure Sensor
- Wiring or connector issues
- Vacuum leaks in the EVAP system
- Software or programming issues
Symptoms of P106B Toyota
- Check Engine Light illuminated
- Reduced fuel efficiency
- Rough idling or stalling
- Increased emissions output
- Failed emissions test
How to Fix P106B Toyota
- Diagnose the specific cause of the issue using a scan tool to determine which sensor is faulty.
- Inspect the wiring and connectors for any damage or corrosion, and repair or replace as necessary.
- Test the sensors using a multimeter to ensure they are functioning correctly.
- Replace the faulty sensor(s) with OEM or high-quality aftermarket parts.
- Clear the DTC and perform a test drive to ensure the issue has been resolved.
Cost to Fix P106B Toyota
