This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer found a problem with how it checks the amount of ethanol in the fuel. It's like the car is confused about the type of fuel it's using.
The control module monitors the ethanol content in the fuel to adjust engine performance. This code indicates an error in this monitoring process.
The P327B code is triggered when the control module detects a discrepancy in the ethanol content reading from the fuel system. This can affect how the engine adjusts for different fuel types, potentially leading to performance issues.
• Check Engine Light on
• Poor fuel economy
• Engine performance issues
• Faulty ethanol content sensor
• Wiring issues in the ethanol sensor circuit
• Software glitch in the engine control module
Ethanol: A type of alcohol used as fuel.
Control Module: The computer that manages engine operations.
• Use an OBD-II scanner to confirm the code.
• Inspect the ethanol content sensor and its wiring for damage.
• Check for software updates for the engine control module.
• Replace the ethanol content sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or update the engine control module software.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Silverado
• Ford F-150
• Toyota Camry
• Regularly check and maintain the fuel system.
• Use high-quality fuel.
• Ensure timely software updates for the control module.
Sensor Issue
• Avoid using low-quality fuel.
• Regularly service the vehicle to prevent sensor issues.
Check with the manufacturer for specific warranty coverage on emissions-related components.
This code has become more common with the increased use of ethanol-blended fuels in modern vehicles.
Moderate – It should be addressed soon to prevent potential engine performance issues.
Ignoring this code can lead to increased emissions and potential damage to the engine.
• Vehicle at operating temperature
• Stable fuel level
The ethanol content sensor is typically located near the fuel tank or along the fuel line.
Q: Can I drive with a P327B code?
A: It's possible to drive, but it's best to fix the issue soon to avoid performance problems.
Q: Does this code affect fuel economy?
A: Yes, incorrect ethanol readings can lead to poor fuel economy.
