[SOLVED] P245B Code: Fix Your Egr Cooler Bypass Control Circuit Now!

The P245B fault code in automobiles indicates a problem with the Exhaust Gas Recirculation (EGR) Temperature Sensor. 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 to be around 1.0 hour.

To interpret the fault code, it is recommended to check the possible causes listed above and look for any broken, bent, pushed out, or corroded connector pins.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p245b fault code.

Here are the symptoms to look out for:

  • The P245B fault code in automobiles can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light, decreased fuel efficiency, reduced engine power, difficulty starting the engine, and increased emissions.
  • It can also cause the diesel particulate filter to become clogged, leading to a buildup of soot and ash in the filter.
  • If left untreated, this can cause serious damage to the engine and other components of the vehicle.
  • It is important to address this issue as soon as possible to avoid costly repairs and potential safety hazards.

The p245b automobile fault code can be caused by issues with the coolant system, EGR cooler, or EGR temperature sensor.

  • The automobile fault code P245B 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 p245b, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p245b, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and 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 P245B can be diagnosed and fixed within an estimated repair time of 1.0 hour.

The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.

Therefore, the total cost of fixing the P245B fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P245B 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, while the second portion monitors the EGR temperature.

If the EGR Cooler Bypass valve is in bypass mode incorrectly, the exhaust gas recirculation temperatures will exceed a temperature limit, triggering the fault. The ECM will light a MIL lamp immediately after this diagnostic runs and fails, and turn it off after the diagnostic passes in four consecutive drive cycles.

What are the possible causes of the P245B fault code in an automobile?

If the engine light is on and the P245B fault code is detected, it could be due to issues with the coolant system, EGR cooler, faulty EGR temperature sensor, or poor electrical connection in the EGR temperature sensor circuit. To fix this, inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.

How can one visually inspect the related wiring harness and connectors to fix the P245B fault code?

If you’re experiencing the P245B 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, faulty EGR temperature sensor, or poor electrical connection in the EGR temperature sensor circuit. 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.

What are the consequences of ignoring the P245B fault code in an automobile?

Ignoring the P245B 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. Failure to address the issue can result in reduced engine performance, decreased fuel efficiency, and potential damage to the engine. It is important to visually inspect the related wiring harness and connectors and check for damaged components to avoid further complications.
