• Solutions

The P00AE code indicates an issue with the Intake Air Temperature (IAT) Sensor 1 circuit for Bank 2. This sensor measures the temperature of the air entering the engine, which is vital for optimal engine performance and efficiency. An intermittent or erratic signal from this sensor can cause poor fuel economy, increased emissions, and reduced engine power.

What are the symptoms of the P00AE code?

Drivers may experience a variety of symptoms when facing a P00AE code:

• Check Engine Light (CEL) illuminated on the dashboard.
• Decreased engine performance and acceleration.
• Noticeable decrease in fuel efficiency.
• Engine stalling or rough idling in some cases.
• Irregular engine behavior, particularly under load or acceleration.

What causes the P00AE code?

Several factors can lead to the P00AE fault code:

• A faulty Intake Air Temperature Sensor 1.
• Poor electrical connections or damaged wiring in the sensor circuit.
• Corrosion or contamination in the sensor connectors.
• Issues with the Engine Control Module (ECM) affecting sensor readings.
• Air intake leaks that create erroneous temperature readings.

How to fix P00AE?

To resolve the P00AE code, consider the following steps:

• Inspect and replace the Intake Air Temperature Sensor 1 if faulty.
• Check the wiring and connectors for any signs of damage, corrosion, or loose connections.
• Clean any corrosion from the electrical connectors and ensure they are securely connected.
• Test the sensor's resistance and voltage outputs to verify functionality.
• If all physical components are intact, a reprogramming or update to the ECM may be necessary.
