What is P242B : Engine Error code Causes Explained
When the diesel particulate filter (DPF) temperature sensor reads abnormally, the P242B engine error code indicates a problem. This issue can compromise DPF regeneration, engine performance, and emissions.
How to Identify a DTCs Number
The P242B engine error code typically refers to a problem related to the evaporative emission system, specifically the “Evaporative Emission System Pressure Sensor A Circuit Range/Performance.”
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 a DTC (Diagnostic Trouble Code) number, you will typically use an OBD-II scanner. When you connect the scanner to your vehicle’s OBD-II port, it will read and display any stored codes, including the P242B code, along with other relevant diagnostic information.
Causes of P242B Error Code:
- Faulty Exhaust Gas Temperature Sensor.
The sensor may be damaged, dirty, or malfunctioning. - Wiring or Connector Issues:
Corrosion, loose connections, or damaged wires in the EGT sensor circuit. - Excessive Carbon Buildup:
Buildup in the exhaust system affecting sensor function. - Exhaust System Issues:
Leaks or damage affecting sensor readings. - ECU/PCM Malfunction:
Incorrect processing of EGT sensor data.
Risk Level of P242B Error Code:
A high-risk level associated with this error suggests that there could be a serious problem, potentially affecting the vehicle’s performance, fuel efficiency, and emissions control.
Regular diagnostics and immediate repairs are recommended to avoid long-term damage and ensure safe vehicle operation

FAQ’s
What is the P242B Engine Error Code?
The P242B engine error code indicates a problem with the diesel particulate filter (DPF) regeneration process. Specifically, it points to an issue with the DPF temperature sensor or the filter’s ability to complete the regeneration cycle.
What are the Causes of the P242B Error Code?
Common causes of the P242B error code include a malfunctioning DPF temperature sensor, clogged or damaged DPF, or issues with the engine’s exhaust system. These issues prevent the proper regeneration of the filter.
What is the Risk Level of the P242B Code?
The P242B code is considered high-risk because it can lead to reduced engine performance, increased fuel consumption, and potential engine damage if the DPF continues to clog without proper regeneration.
Which Vehicles are Affected by the P242B Error Code?
Vehicles equipped with a diesel engine and a DPF system, including models from manufacturers like Ford, Volkswagen, Jeep, Chevrolet, BMW, Audi, and Dodge are most commonly affected by this error code.
