P245C - OBD Trouble Code

<<See All OBD Codes

Do you find the ECM to be faulty? Are the connectors broken? Then there is a high probability that the P245C error is stored in the vehicle. The PCM fault is generally known as the exhaust gas recirculation cooler bypass control circuit low. The exhaust gas is sent back to the engine by the EGR valve so that the unburnt fuel which is leftover will be burnt completely. The PCM is automated to go around the EGR cooler under a specific driving environment. The monitoring of the system is done by the ECM to ensure that the bypass valve functions as expected. Failure of the EGR bypass valve to function correctly will result in the storing of the P245C error code.

During active regeneration mode, the EGR cooler bypass valve will evade the EGR cooler. Further pollution of the EGR cooler will be prevented. For this diagnostic procedure, there are 2 portions. The ECM will drive the control line between low and high and check the accurate status response when the key is on. The correct status response voltage is set between 5-8 volts throughout the engine operation. The EGR cooler bypass valve will send 1.0 and 1.7 voltage signal. When this takes place, an error will be stored. The incorrect bypass mode of the EGR cooler bypass valve will make the EGR temperature to exceed the limit which also triggers a fault during this situation. Illumination of the MIL will be set by the ECM, once the diagnostic process fails. The Mil will be turned off, once the diagnostic process turns successful in all 4 consecutive drive cycles by the ECM.

What causes this problem with the Exhaust Gas Recirculation Cooler Bypass Control Circuit Low?

• Faulty EGR cooler bypass valve.
• Blocked or faulty EGR cooler.
• Temperature switch might be broken.
• Unnecessary carbon buildup.
• The electrical wires might be broken or defective.
• Rusted, broken or unattached connectors.
• Malfunctioning ECM.

1. Exhaust Gas Recirculation Cooler - To get rid of the P245C error in the vehicle the faults in the exhaust gas recirculation cooler has to be fixed or replaced instantly.
2. Exhaust Gas Recirculation Cooler Bypass Valve - Are you looking to replace the faulty exhaust gas recirculation cooler bypass valve? Then get it from Parts Avatar at the best prices online.
3. Powertrain Control Module - The PCM will monitor and compensate for any change in altitude and looks after the overall health of your car. The right replacement for your faulty powertrain control module can be found at Parts Avatar at the best prices.
4. Engine Control Module - You can easily find out that the engine control module in your vehicle is damaged if your vehicle faces issues like stalling or misfiring. Additionally, the behavior of the engine can be erratic. In one such scenario, it is always best to replace the faulty engine control module.
5. Coolant Temperature Sensor - Illumination of the check engine light will take place if the coolant temperature sensor is damaged. Avoid the P245C error by replacing it instantly.
6. Coolant System - The coolant system will start malfunctioning if the water pump overheats and stop working. Replace it as soon as possible.

Willing to know some common symptoms of OBD Code P245C? Your wish is our demand. Have a look at them below:

Common Symptoms

• Failure of the emission test by the engine.

If you want to easily diagnose this fault code P245C, then all you have to do is to follow the steps which are mentioned below:

• Start with the help of a troubleshooting procedure, and check for the correct Technical Service Bulletins (TSB's) specifically designed for your vehicle by year, model and transmission. You can save enough time in the long run as it guides you in the right path.
• Locating the components linked with EGR cooler bypass circuit and checking for damages is the second step.
• The circuit will include several parts like temperature switch, bypass valve, EGR valve, EGR cooler, and the ECM depending on the particular vehicle.
• Now, perform a visual inspection of the wires for injuries like scraping, rubbing, or burn spots.
• Check for the connector as well as its connection if they are properly secured and if there is any corrosion or damaged pins.
• You may also have to visually examine the connectors and its associated connections for protection, erosion and damaged pins.
• In this process, you must inspect all the wires and its connections to components which also contains the EGR temperature switch and the ECM.
• Validate the configuration of the EGR cooler bypass valve control circuit by verifying the particular tech data and make sure that every part is included in the circuit which may also contain the fuse or a fuse-able link in some applications.

Advanced Steps

• The advanced procedure varies for every vehicle as they are specific and need proper diagnostic tools to carry out the diagnosis.
• Use a digital multimeter and appropriate technical references for your vehicle to start the process.

Voltage checks

• Depending on the vehicle and the configuration of the circuit, the permitted range and reference voltage will vary.
• The correct order and troubleshooting charts are included in the specific technical data to help in the proper diagnosis.
• If there is no power source and ground during the process, the continuity test must be done to verify the reliability of the wires, connectors, and other components.
• Whenever the continuity test is done, the normal readings for wires and connectors should be set to 0 ohms resistance and the power must be detached from the circuit.
• Wires which are open, shorted or corroded is an indication for no resistance or continuity and it must be quickly fixed.

Common Mistakes When Diagnosing the P245C Code

• The EGR cooler assembly might be defective.
• Defective EGR cooler bypass valve.
• Failure of the PCM.
