[SOLVED] P2473 Code: Fixing Exhaust Gas Temperature Sensor Circuit

The P2473 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 fuel efficiency.

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.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2473 fault code. Here are the symptoms to look out for:

  • The P2473 fault code in automobiles can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include a decrease in engine power, reduced fuel efficiency, and difficulty shifting gears.
  • Additionally, the vehicle may experience a decrease in acceleration, a rough idle, or a complete failure to start.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code P2473 can be caused by a range of issues, including faulty sensors, poor electrical connections, exhaust leaks, and particulate buildup.

  • The automobile fault code P2473 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 P2473 fault code.

Below are the possible fixes for the automobile fault code p2473, including inspecting wiring harness and connectors for damage.

  • To fix the automobile fault code P2473, 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 P2473 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 P2473 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P2473 code is related to the Exhaust Gas Temperature Sensor (EGTS). The EGTS is responsible for detecting exhaust gas temperature and converting it into a voltage. The PCM monitors the EGTS for proper circuit continuity and out of range high values.

The code is set when the EGTS is out of factory specifications. The EGTS is located in front of the Diesel Oxidation Catalyst (DOC) andor in front of the Diesel Particulate Filter (DPF). The P2473 code specifically refers to the Exhaust Gas Temperature Sensor Circuit Bank 2 S.

What are the possible causes of the automobile fault code P2473?

If you see the engine light on or service engine soon warning light, it could be due to the P2473 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.

How can I fix the P2473 fault code in my automobile?

If you’re experiencing the P2473 fault code in your automobile, you may notice the engine light or service engine soon warning light is on. This is likely due to 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, visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
