If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2489 fault code. This code indicates a problem with the Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 5. The possible causes include a faulty sensor, open or shorted harness, poor electrical connection, exhaust leaks, or excessive particulate matter buildup on the sensor.

The repair importance is high as it can affect the engine’s performance and emissions. The repair difficulty is moderate, and it takes around 1.0 hour to fix. To interpret the fault code, check the possible causes and visually inspect the related wiring harness and connectors for any damage or corrosion.

Repair Importance Level6.67 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level6.67 (Out of 10)

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2489 fault code.

Here are the symptoms to look out for:

  • The P2489 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 reduced engine power, decreased fuel efficiency, and rough idling.
  • Additionally, the vehicle may experience stalling or difficulty starting, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code p2489 can be caused by a range of issues, including a faulty sensor, poor electrical connection, exhaust leaks, and particulate buildup.

  • The automobile fault code P2489 can be caused by a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 5.
  • It can also be caused by an open or shorted Exhaust Gas Temperature Sensor Bank 2 Sensor 5 harness.
  • A poor electrical connection in the Exhaust Gas Temperature Sensor Bank 2 Sensor 5 circuit can also trigger this fault code.
  • Additionally, exhaust leaks and excessive particulate matter buildup on the sensor can cause the P2489 fault code.

Below are the possible fixes for the automobile fault code p2489, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p2489, 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.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P2489 indicates a problem with the engine coolant thermostat. The estimated repair time for this fault code is 1.0 hour.

The cost of fixing this fault code is influenced by the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour.

Other factors that may affect the cost of fixing this fault code include the severity of the problem, the type of vehicle, and the availability of replacement parts.

The P2489 code is related to the Exhaust Gas Temperature Sensor (EGTS).

The EGTS detects exhaust gas temperature and converts it into a voltage. It feeds back to the PCM with the voltage signal to control engine conditions and reduce emissions.

The code is set when the EGTS is out of factory specifications. Specifically, it indicates an intermittent or erratic circuit in Bank 2 Sensor 5. The EGTS is located in front of the Diesel Oxidation Catalyst (DOC) andor in front of the Diesel Particulate Filter (DPF).

The PCM continuously monitors the EGTS for proper circuit continuity and high values.

What are the possible causes of the automobile fault code P2489?

If you see the engine light on or service engine soon warning light, it could be due to the P2489 fault code. This code is usually caused by a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 5, 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 P2489 fault code in my automobile?

If you’re experiencing the P2489 fault code in your automobile, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, it could be due to a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 5, an open or shorted Exhaust Gas Temperature Sensor Bank 2 Sensor 5 harness, a poor electrical connection in the Exhaust Gas Temperature Sensor Bank 2 Sensor 5 circuit, exhaust leaks, or excessive particulate matter buildup on the sensor. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

What should I visually inspect to troubleshoot the P2489 fault code?

If you’re troubleshooting the P2489 fault code, start by checking for an illuminated Engine Light or Service Engine Soon Warning Light. The cause of this issue could be a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 5, an open or shorted harness, poor electrical connection, exhaust leaks, or excessive particulate matter buildup on the sensor. To fix the issue, visually inspect the related wiring harness and connectors, checking for damaged components and broken, bent, pushed out, or corroded connector pins.
