[SOLVED] P245C Code: Low Egr Cooler Bypass Control – Fix Now!

The P245C automobile fault code indicates a problem with the Exhaust Gas Recirculation (EGR) Temperature Sensor circuit. This can cause the engine light to turn on, indicating a potential issue with the coolant system or EGR cooler. The cause of this fault code could be a faulty EGR temperature sensor, an open or shorted EGR temperature sensor harness, or a poor electrical connection in the EGR temperature sensor circuit.

It is important to visually inspect the wiring harness and connectors for any damage or corrosion.

The repair time for this fault code is estimated at 1.0. To interpret the fault code, it is recommended to check the “Possible Causes” listed above and perform a thorough inspection of the related components.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p245c fault code. Here are the symptoms to look out for:

  • The P245C fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light, decreased fuel efficiency, reduced engine power, difficulty starting the engine, rough idling, stalling, and increased emissions.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code p245c can be caused by issues related to the coolant system, EGR cooler, and EGR temperature sensor.

  • The automobile fault code P245C can be caused by several factors.
  • These include issues with the coolant system, a faulty EGR cooler, a faulty Exhaust Gas Recirculation (EGR) Temperature Sensor, an open or shorted EGR Temperature Sensor harness, and poor electrical connection in the EGR Temperature Sensor circuit.
  • It is important to address all of these potential causes in order to properly diagnose and fix the issue.

Below are the possible fixes for the automobile fault code p245c, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p245c, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P245C can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour. Therefore, the total cost of diagnosis and fixing the P245C fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time.

The P245C code is related to the Exhaust Gas Recirculation (EGR) Cooler bypass valve. It is used to bypass the EGR cooler during active regeneration mode to prevent fouling.

The diagnostic has two portions. The first portion monitors the correct status response of the control line. The second portion monitors the EGR temperature.

If the bypass valve is in bypass mode incorrectly, the EGR temperature will exceed a limit and trigger the fault. The ECM will light a MIL lamp immediately after the diagnostic fails and turn it off after four consecutive drive cycles.

What are the possible causes of the P245C fault code in an automobile?

If you see the engine light on or service engine soon warning light, it could be due to the P245C fault code. This code is related to the Exhaust Gas Recirculation (EGR) Temperature Sensor and can be caused by issues with the coolant system, EGR cooler, faulty EGR temperature sensor, or poor electrical connection. To fix this, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the P245C fault code?

If you’re experiencing the P245C fault code, which is indicated by the engine light or service engine soon warning light turning on, there are a few possible causes to consider. These include issues with the coolant system, EGR cooler, or a faulty exhaust gas recirculation (EGR) temperature sensor. To fix the issue, start by visually inspecting the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. This can help identify any issues with the EGR temperature sensor circuit’s electrical connection.

What are the consequences of ignoring the P245C fault code in an automobile?

Ignoring the P245C fault code in an automobile can lead to serious consequences. The engine light will remain on, indicating a problem with the coolant system, EGR cooler, or faulty exhaust gas recirculation temperature sensor. Ignoring this code can cause damage to the engine and result in costly repairs. It is important to visually inspect the related wiring harness and connectors and check for damaged components to avoid further damage.

p245c error fault code explained

If your engine light is on due to P245C fault code, check your coolant system, EGR cooler, and Exhaust Gas Recirculation (EGR) Temperature Sensor. Visually inspect the wiring harness and connectors for damage or corrosion. Look for broken, bent, pushed out, or corroded connector’s pins.
