This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with a sensor in your car that measures air pressure. It's like when a balloon is too full of air, and the sensor is saying, 'Hey, there's too much pressure!'
The P11AE code indicates that the voltage signal from the manifold absolute pressure (MAP) or barometric pressure sensor on bank 2 is higher than expected.
The MAP sensor measures the pressure inside the intake manifold, while the barometric pressure sensor measures the atmospheric pressure. A high circuit reading suggests an electrical issue, such as a short circuit or a faulty sensor, which can affect engine performance.
• Check Engine Light is on
• Poor engine performance
• Decreased fuel efficiency
• Faulty MAP sensor
• Wiring issues, such as a short to voltage
• Faulty barometric pressure sensor
MAP Sensor: Manifold Absolute Pressure Sensor, measures the pressure in the intake manifold.
Bank 2: Refers to the side of the engine opposite Bank 1, typically on V-type engines.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the MAP sensor voltage output with a multimeter.
• Replace the faulty MAP sensor.
• Repair or replace damaged wiring or connectors.
• Replace the barometric pressure sensor if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect and maintain sensor wiring.
• Ensure sensors are clean and free from debris.
• Perform routine diagnostic checks.
Sensor Issue
• Address the issue promptly to avoid further engine problems.
• Consult a professional mechanic if unsure about the diagnosis.
Check with your vehicle's manufacturer for specific warranty coverage on sensors.
This code has been associated with issues in vehicles with aging sensors or those exposed to harsh environmental conditions.
Moderate – It should be addressed soon to prevent potential engine performance issues.
Driving with a faulty sensor can lead to increased emissions and may not comply with local emissions regulations.
• Engine at operating temperature
• Vehicle in a safe, stationary position
The MAP sensor is typically located on or near the intake manifold of the engine.
Q: Can I drive my car with a P11AE code?
A: It's possible, but not recommended as it can lead to poor engine performance and increased emissions.
Q: Will a P11AE code affect fuel efficiency?
A: Yes, a faulty sensor can cause incorrect air-fuel mixture, reducing fuel efficiency.
