What is P242D : Engine Error code Causes Explained
The P242D engine trouble code indicates a low-temperature diesel particulate filter (DPF) malfunction. Poor vehicle performance and higher emissions may result from filter regeneration interference.
How to Identify a DTCs Number
The P242D engine error code typically indicates a problem with the diesel particulate filter (DPF) pressure sensor circuit.
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
To identify the DTC number for this error code, you would typically use an OBD-II scanner or diagnostic tool. Plug the scanner into your vehicle’s OBD-II port, which is usually located near the driver’s seat under the dashboard. The scanner will then read the DTCs (Diagnostic Trouble Codes) stored in the vehicle’s ECU, displaying the specific error code, including P242D.
Causes of P242D Error Code:
- Faulty Exhaust Gas Temperature Sensor.
The most common cause is a faulty sensor due to damage, contamination, or aging. - Damaged sensor wiring:
Damaged or corroded wires to the EGT sensor can disrupt the PCM signal. - Poor electrical connection:
Loose connections at the sensor or connector can cause intermittent issues. - Powertrain Control Module (PCM) malfunction:
In rare cases, the PCM itself may be faulty and misinterpreting the EGT sensor data. - Exhaust system leaks:
Significant exhaust leaks near the EGT sensor can affect its readings.
Risk Level of P242D Error Code:
The P242D engine error code indicates a High risk Level. It is important to address this error immediately to prevent more severe engine or emissions system damage.
Common Car Brands Affected by P242D Code:
The P242D engine error code is commonly found in the following list.
- Ford
- Volkswagen
- Jeep
- Chevrolet
- BMW
- Audi
- Dodge

FAQ’s
What is the P242D Engine Error Code?
The P242D error code indicates a problem with the diesel particulate filter (DPF) temperature sensor. This code typically triggers when the sensor’s readings are out of range, signaling potential issues with exhaust filtration.
What Causes the P242D Engine Error Code?
The P242D error code is often caused by a malfunctioning DPF temperature sensor, damaged wiring, or issues with the vehicle’s exhaust system. Poor sensor calibration or soot buildup can also trigger the code.
What is the Risk Level of the P242D Error Code?
The risk level for this error code is considered high. Ignoring it can lead to engine performance issues, reduced fuel efficiency, and potential damage to the DPF system, which may require expensive repairs.
Which Vehicles are Affected by the P242D Error Code?
The P242D error code typically affects vehicles with diesel engines, like Ford, Volkswagen, Jeep, Chevrolet, BMW, Audi and Dodge.
