P00AB - OBD Trouble Code

<<See All OBD Codes

If you are experiencing unusual response of the throttle, lack of power from the car engine, impact on the fuel economy and frequent illumination of the Check Engine Light, it might be an indication of the OBD Code P00AB error.

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

This diagnostic trouble code (DTC) is a generic powertrain code, which applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model. The IAT (Intake Air Temperature) sensor varies in resistance based upon the temperature of the engine intake air, typically located in the air intake ductwork and is usually a two wire sensor. 5 Volts is supplied to one wire from the PCM (Powertrain Control Module) and the other is a ground. The powertrain control module (PCM) monitors the change in the voltage supplied to determine air temperature to run the engine at the most efficient conditions possible at that given temperature.

What causes the problem with the IAT Sensor Circuit?

• Faulty Intake Air Temperature sensor and circuit
• Short or broken Wiring and harness related to the sensor
• Poor electrical connection to the Intake Manifold
• PCM being faulty and interpreting wrong readings

1. Air Temperature Sensor - The Air Temperature sensor detect the air entering the engine that directly affects the engine performance. It is important to replace faulty sensor immediately.
2. Air Intake Kits - Air intake system faults hamper the air to fuel ratio thus affecting the engine power. Buy quality air intake kits from us.
3. Engine Control Module - OBD Error Code P00AB can also be due to problem with the ECM. Get the faulty electricals replaced as soon as possible.
4. Powertrain Control Module - P00AB error code also relates to problems with the PCM. Find the right components with us.
5. MAF Sensor - Damaged/faulty Mass Air Flow sensor should be replaced immediately, as it hampers the engine performance.
6. Diagnostic Tool - Grab amazing deals on diagnostic tools to scan for all the OBD error flashing in the system.

Symptoms of a P00AB code may include:

• Reduced fuel efficiency
• Lack of power and response from the engine
• Lost response at idle or upon light acceleration
• PCM may store other OBD error codes too

Proper scan tools should be used to detect and diagnose the problems related to a particular OBD error code. After testing it is important to check that the error doesn’t reflect back anymore. Some of the common components that account to the major problems of the P00AB error code and their solutions are:

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

P00AB 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.
