P245C Fault Code

Exhaust Gas Recirculation Cooler Bypass Control Circuit Low

• What does that mean?
• Symptoms
• Causes
• Solutions

The P245C fault code indicates that there is an issue with the Exhaust Gas Recirculation (EGR) Cooler Bypass Control Circuit being low. This component plays a vital role in reducing emissions by recirculating a portion of the exhaust gases back into the engine. When the control circuit experiences a low signal, it can lead to inefficiencies in the EGR system, impacting engine performance and emissions levels.

What are the symptoms of the P245C code?

Drivers may notice several symptoms related to the P245C code:

• Decreased engine performance or efficiency
• Increased exhaust emissions, possibly leading to failed emissions tests
• Changes in fuel consumption patterns
• Engine warning light illuminated on the dashboard
• Possible rough idling or stalling in some situations.

What causes the P245C code?

Common causes for the P245C code include:

• Faulty EGR cooler bypass control valve
• Damaged wiring or connectors in the EGR system
• Short circuits or open circuits in the bypass control circuit
• A malfunctioning EGR control module or sensor
• Clogging in the EGR passages that could affect readings.

How to fix P245C?

To address the P245C error code, consider the following steps:

• Inspect and repair any damaged wiring or connectors related to the EGR cooler bypass control circuit.
• Test the EGR cooler bypass control valve for proper functionality and replace it if faulty.
• Ensure that the EGR passages are clear of debris or carbon buildup.
• If necessary, reprogram or replace the EGR control module, following your vehicle manufacturer's guidelines.
• Clear the trouble codes and perform a test drive to ensure the issue is resolved.
