Oftentimes, Engine Warning Light turns up almost immediately it senses the OBD code P00AE error. This directly impacts the engine performance as it struggles with power and acceleration as well as failed fuel system causing increased consumption of fuel by the engine.

OBD-II Code Decreased engine performance is defined as an Intake Air Temperature Sensor 1 Circuit Intermittent

This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model. The powertrain control module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor The IAT is a thermistor that varies resistance based on temperature. As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts for the #2 IAT sensor, it sets this P00AE check engine light code. Bank 2 is the side of the engine that does not contain cylinder #1.

What causes the problem with the IAT Sensor Circuit?

• Problematic IAT (Intake Air Temperature) Sensor
• Faulty wiring/ connections to the IAT sensor and circuit
• PCM (Powertrain Control Module) fault in sensor
• Break in the intake/inlet pipe
• Intake/inlet pipeline getting clogged
• MAF (Mass Airflow Sensor) damaged

1. Engine Control Module - OBD Error Code P00AE can also be due to faulty ECMs. This may lead to engine stalling or not starting, and check engine lights being on. Replace faulty electrical components now!
2. Powertrain Control Module - P00AE error code can also relate to PCM related problems. Find and replace all the Powertrain related parts with us.
3. Diagnostic Tool - Choose from our wide variety of professional diagnostic tools to detect and correct the OBD code error.
4. Auto Switches & Sensors - Common causes behind OBD error code can be defective switches or faulty sensors. Thus, check and replace damaged switches and sensors now.
5. Air Temperature Sensor - The Air Temperature sensor plays an important role in the engine performance and response. Replace faulty sensor now!
6. Air Intake Kits - Air intake system and important to maintain the proper air to fuel ratio. Buy quality air intake kits from us.
7. MAF Sensor - Faulty Mass Air Flow sensor can cause engine stalling and not starting as well as lost accelerations and power. Thus, replace the faulty one now! 

Since this code is likely points to the problem on the IAT circuit, there may not be any noticeable big symptoms at present and even if there are any can we considered as general problems by the driver. However, the MIL will likely be on and the car may exhibit some drivability problems.

Symptoms of a P00AE code may include:

• Slightly Increased fuel consumption
• Declined engine performance
• Loss of engine power & acceleration
• Other drivability codes stored in PCM

• Replace faulty Intake Air Temperature Sensor and Circuit
• Repair or replace damaged wiring/connections to the IAT Sensor
• Replace PCM (Powertrain Control Module) if damaged and can also be reprogrammed if found faulty and tested again if the error reappears or not

P00AE is properly diagnosed with an advanced scan tool capable of factory sensor readings (not just one from an auto parts store). A qualified technician can read the data from the advanced scan tool to determine when the problem occurred, or if it is still occurring. They may clear the code/light and test drive the vehicle while monitoring the scan tool data to see if the fault returns or is present.Based upon the conditions of the test, possibly clearing the code, and road testing the car while monitoring the data, further diagnosis may be required. Diagnosis may require multiple tools such as:

• IAT (Intake Air Temperature) Sensor replacement if found faulty
• Replacement of Damaged wiring/connections to the IAT (Intake Air Temperature) Sensor
• Repair faulty PCM sensor that may require reprogramming
• Replace Leaky and damaged intake/inlet pipe immediately
• Faulty MAF (Mass Airflow Sensor) needs replacement as it directly hampers the engine performance

Common Mistakes When Diagnosing OBD Code P00AE

Some of the common mistakes done while changing diagnosing the OBD code P00AE are:

• Improper assessment of the IAT sensor failure
• Simply replacing the Powertrain Control Module (PCM) without considering other possibilities of problem
• Not noticing the damaged or loosened wiring and circuit problems
