Laymans terms

This code means that the car's computer has detected that the temperature of the exhaust gases on one side of the engine is not what it expects. It's like when you expect your soup to be hot, but it's cold instead.

Explanation

The P247D code indicates that the exhaust gas temperature sensor, located on Bank 2 Sensor 2, is reporting a temperature that is outside the expected range.

Technical description

The exhaust gas temperature sensor measures the temperature of the exhaust gases leaving the engine. Bank 2 refers to the side of the engine that does not contain cylinder 1. Sensor 2 is typically located further down the exhaust system, often after the catalytic converter. This sensor helps the engine control module (ECM) monitor and adjust the engine's performance for optimal efficiency and emissions control. If the sensor reports a temperature that is too high or too low, the ECM triggers the P247D code.

Symptoms

• Check Engine Light illuminated

• Poor fuel economy

• Reduced engine performance

Common Causes

• Faulty exhaust gas temperature sensor

• Wiring issues or poor electrical connections

• Exhaust leaks affecting sensor readings

Glossary

Bank 2: The side of the engine opposite Bank 1, which does not contain cylinder 1.

Sensor 2: The second sensor in the exhaust system, typically located after the catalytic converter.

Diagnosis steps

• Use an OBD-II scanner to confirm the code.

• Inspect the exhaust gas temperature sensor and its wiring for damage.

• Test the sensor's resistance and compare it to specifications.

Repair procedures

• Replace the faulty exhaust gas temperature sensor.

• Repair or replace damaged wiring or connectors.

• Fix any exhaust leaks.

Tools required

• OBD-II scanner

• Multimeter

• Wrench set

Estimated repair cost

$150 - $300

Difficulty level

Moderate

Commonly affected vehicles

• Ford F-150

• Chevrolet Silverado

• Ram 1500

Preventive measures

• Regularly inspect and maintain the exhaust system.

• Ensure timely replacement of faulty sensors.

• Check for exhaust leaks periodically.

Error code type

Sensor Issue

User experience recommendations

• Have a professional diagnose and repair the issue.

• Avoid driving with the Check Engine Light on for extended periods.

• Regular vehicle maintenance can prevent such issues.

Warranty information

Check with your vehicle manufacturer for warranty coverage on emissions-related components.

Historical data

Exhaust temperature sensor issues have been common in vehicles with advanced emissions systems, especially in models with multiple catalytic converters.

Urgency level

Moderate – This issue can affect vehicle performance and emissions, so it should be addressed promptly.

Testing conditions

• Engine at operating temperature

• Vehicle in a safe, stationary position

Component location

The exhaust gas temperature sensor is located on the exhaust pipe of Bank 2, typically after the catalytic converter.

FAQs

Q: Can I drive my car with a P247D code?
A: While you may be able to drive with this code, it's not recommended as it can affect your vehicle's performance and emissions.

Q: How do I know if my exhaust gas temperature sensor is faulty?
A: A faulty sensor may cause the Check Engine Light to come on, and you might notice poor fuel economy or reduced engine performance.
