The P2477 fault code in automobiles indicates a problem with the Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 4. The most common symptom is the illumination of the Engine Light or Service Engine Soon Warning Light.

The cause of this fault code could be a faulty EGTS, open or shorted harness, poor electrical connection, exhaust leaks, or excessive particulate matter buildup on the sensor. The importance of repairing this issue lies in the fact that it affects the vehicle’s emissions and performance. The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins.

The repair time is estimated to be around 1.0 hour.

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the p2477 fault code. Here are the symptoms to look out for:

  • The P2477 fault code in an automobile can cause several symptoms.
  • The most common symptom is the illumination of the engine light or service engine soon warning light.
  • Other symptoms include a decrease in engine power, poor acceleration, and reduced fuel efficiency.
  • The vehicle may also experience difficulty shifting gears, and the transmission may slip or fail to engage.
  • Additionally, the driver may notice a burning smell or hear unusual noises coming from the engine or transmission.
  • If you experience any of these symptoms, it is important to have your vehicle inspected by a qualified mechanic as soon as possible.

The automobile fault code P2477 can be caused by various factors, including a faulty sensor, open or shorted harness, poor electrical connection, exhaust leaks, and particulate matter buildup.

  • The automobile fault code P2477 can be caused by a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 4.
  • It can also be caused by an open or shorted Exhaust Gas Temperature Sensor Bank 2 Sensor 4 harness.
  • A poor electrical connection in the Exhaust Gas Temperature Sensor Bank 2 Sensor 4 circuit can also trigger this fault code.
  • Additionally, exhaust leaks and excessive particulate matter buildup on the sensor can cause the P2477 fault code.

Below are the possible fixes for the automobile fault code p2477, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P2477, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • Ensure that all the connections are secure and free from corrosion.
  • This repair process takes an estimated time of 1.0 hour.

The automobile fault code P2477 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 P2477 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P2477 code is related to the Exhaust Gas Temperature Sensor (EGTS) circuit.

The EGTS is responsible for detecting exhaust gas temperature and converting it into a voltage signal.

The PCM monitors the EGTS for proper circuit continuity and out of range high values. If the EGTS is out of factory specifications, the PCM sets the P2477 OBDII code.

This code specifically refers to an intermittent or erratic circuit issue in Bank 2 S.

What are the possible causes of the automobile fault code P2477?

If you see the engine light on or service engine soon warning light, it could be due to the P2477 fault code. This code is usually caused by a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 4, an open or shorted harness, poor electrical connection, exhaust leaks, or excessive particulate matter buildup on the sensor. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector’s pins.
