P1459 Audi Code - Exhaust Gas Temperature Sensor 2 Range/Performance
Quick Answer
The P1459 code for Audi vehicles refers to an issue with the Exhaust Gas Temperature (EGT) Sensor 2, indicating a range/performance problem. Common causes include Faulty EGT Sensor: The sensor itself may be defective or damaged, causing it to send incorrect temperature readings to the ECM, Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the EGT sensor can disrupt the signal transmission, Exhaust System Leaks: Leaks in the exhaust system can affect the sensor's ability to accurately measure the temperature of the gases. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1459 Audi Description
The P1459 code for Audi vehicles refers to an issue with the Exhaust Gas Temperature (EGT) Sensor 2, indicating a range/performance problem. This sensor is responsible for monitoring the temperature of the exhaust gases and providing this information to the engine control module (ECM). When the ECM detects that the sensor is not functioning within the expected range or is not performing optimally, it triggers the P1459 code. This can lead to a variety of performance issues and potentially cause long-term damage to the vehicle if left unresolved.
Common Causes of P1459 Audi
- Faulty EGT Sensor: The sensor itself may be defective or damaged, causing it to send incorrect temperature readings to the ECM.
- Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the EGT sensor can disrupt the signal transmission.
- Exhaust System Leaks: Leaks in the exhaust system can affect the sensor's ability to accurately measure the temperature of the gases.
- ECM Malfunction: A problem with the engine control module can also lead to the P1459 code being triggered.
Symptoms of P1459 Audi
- Check Engine Light: The most common symptom associated with the P1459 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A malfunctioning EGT sensor can cause the engine to run inefficiently, leading to decreased fuel economy.
- Decreased Engine Performance: The vehicle may experience a loss of power or acceleration due to incorrect temperature readings from the sensor.
- Rough Idling or Stalling: The engine may idle roughly or even stall if the EGT sensor is not providing accurate data to the ECM.
- Increased Emissions: A faulty EGT sensor can cause the vehicle to emit higher levels of harmful pollutants, leading to emissions test failures.
How to Fix P1459 Audi
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific error codes and determine the exact cause of the problem.
- Inspect EGT Sensor: Check the condition of the EGT sensor and its wiring for any signs of damage or corrosion.
- Replace EGT Sensor: If the sensor is faulty, it will need to be replaced with a new one that meets the manufacturer's specifications.
- Repair Wiring: Address any wiring issues by repairing or replacing damaged wires and ensuring proper connections.
- Clear Codes and Test Drive: After completing the repairs, clear the error codes from the ECM and take the vehicle for a test drive to confirm that the issue has been resolved.
Cost to Fix P1459 Audi
The cost of repairing a P1459 code related to the Exhaust Gas Temperature Sensor 2 range/performance issue can vary depending on the extent of the problem and the specific components that need to be replaced. On average, the parts cost for a new EGT sensor can range from $100 to $200, while labor costs may amount to $100 to $200 as well. Therefore, the total repair cost could be around $200 to $400. It's important to keep in mind that labor rates at auto repair shops can vary, so it's advisable to check with local shops for a more accurate estimate.
