P242E Ford Code - Exhaust Gas Temperature Sensor Circuit Intermittent/Erratic Bank 1 Sensor 3
Quick Answer
The P242E Ford code indicates a problem with the Exhaust Gas Temperature (EGT) Sensor Circuit for Bank 1 Sensor 3. Common causes include Faulty EGT Sensor: The EGT sensor itself may be malfunctioning, sending intermittent or erratic signals to the ECM, Wiring or Connector Issues: Damaged or corroded wiring or connectors in the sensor circuit can disrupt the signal transmission, ECM Malfunction: A problem with the engine control module (ECM) can also cause issues with the EGT sensor circuit. 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 P242E Ford Description
The P242E Ford code indicates a problem with the Exhaust Gas Temperature (EGT) Sensor Circuit for Bank 1 Sensor 3. This sensor is responsible for monitoring the exhaust gas temperature in the exhaust system. The EGT sensor helps the engine control module (ECM) to adjust fuel injection timing and quantity to optimize engine performance and reduce emissions.
Common Causes of P242E Ford
- Faulty EGT Sensor: The EGT sensor itself may be malfunctioning, sending intermittent or erratic signals to the ECM.
- Wiring or Connector Issues: Damaged or corroded wiring or connectors in the sensor circuit can disrupt the signal transmission.
- ECM Malfunction: A problem with the engine control module (ECM) can also cause issues with the EGT sensor circuit.
- Exhaust System Leaks: Leaks in the exhaust system can affect the EGT sensor readings, triggering this code.
- Exhaust Gas Recirculation (EGR) System Problems: Issues with the EGR system can also impact the EGT sensor's performance.
Symptoms of P242E Ford
- Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the dashboard.
- Reduced Engine Performance: The vehicle may experience a decrease in power and acceleration due to incorrect fuel injection calculations.
- Increased Fuel Consumption: A faulty EGT sensor can lead to inefficient fuel combustion, resulting in higher fuel consumption.
- Rough Idle: The engine may idle roughly or inconsistently, indicating a problem with the fuel injection timing.
How to Fix P242E Ford
- Diagnostic Scan: Begin by using a diagnostic scanner to retrieve the specific fault codes and identify the problem with the EGT sensor circuit.
- Inspect Wiring and Connectors: Check the wiring and connectors in the sensor circuit for any damage or corrosion. Repair or replace as necessary.
- Replace EGT Sensor: If the sensor is faulty, replace it with a new, OEM-quality sensor to ensure accurate readings.
- Clear Fault Codes: Once the issue has been resolved, clear the fault codes from the ECM and test drive the vehicle to ensure the problem has been fixed.
Cost to Fix P242E Ford
The typical repair costs for addressing the P242E Ford code can vary depending on the specific cause of the issue. In general, replacing the EGT sensor can cost between $100 and $200, while labor costs can range from $80 to $150 per hour. Additional costs may apply if wiring or connectors need to be repaired or replaced. It's advisable to consult with a trusted mechanic or auto repair shop to get a more accurate estimate based on your vehicle's make and model, as well as local labor rates.
