If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2429 fault code. This code indicates a problem with the Exhaust Gas Temperature (EGT) system. The possible causes include a faulty EGT, an open or shorted EGT harness, poor electrical connection in the EGT circuit, or extreme changes in ambient temperature soon after key ON, engine running.

The repair importance is moderate, and the difficulty level is low. To fix the issue, you need to visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

The repair time is estimated to be around 1.0 hour.

Repair Importance Level10.0 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level10.0 (Out of 10)

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2429 fault code.

Here are the symptoms to look out for:

  • The P2429 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 performance, reduced fuel efficiency, and difficulty starting the engine.
  • Additionally, the vehicle may experience rough idling or stalling, and there may be a noticeable odor of fuel.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code p2429 can be caused by a range of factors, including faulty EGT, open or shorted EGT harness, poor electrical connection, and extreme changes in ambient temperature.

  • The automobile fault code P2429 can be caused by a faulty Exhaust Gas Temperature (EGT).
  • It can also be caused by an open or shorted Exhaust Gas Temperature (EGT) harness.
  • Poor electrical connection in the Exhaust Gas Temperature (EGT) circuit can also trigger this fault code.
  • Additionally, extreme changes in ambient temperature soon after key ON, engine running can also be a cause of the P2429 fault code.

To fix the p2429 fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2429, 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 automobile fault code P2429 is related to the evaporative emission system.

The diagnosis of this code involves checking the fuel tank pressure sensor, the purge valve, and the wiring connections. The fixing cost of this code depends on the estimated repair time, which is 1.0 hour. Most auto repair shops charge between $75 and $150 per hour, which means the fixing cost can range from $75 to $150.

Other factors that can influence the fixing cost include the location of the repair shop, the type of vehicle, and the severity of the problem.

The P2429 code is related to the Exhaust Gas Temperature (EGT) sensor.

The Powertrain Control Module (PCM) monitors the EGT sensor for a biased signal value.

The PCM records the EGT sensor temperature value at key ON, engine OFF after an 8-hour soak. The PCM calculates an expected key ON, engine OFF value after several minutes of vehicle operation at speeds greater than 40.2 kmh (25 mph).

The test fails when the difference between the expected calculated value and the actual recorded value is greater than 40°C (72°F).

The code indicates that the exhaust gas temperature is too high in the bank.

What are the possible causes of the automobile fault code P2429?

If you see the engine light on or service engine soon warning light, it could be due to the P2429 fault code. This code is usually caused by a faulty Exhaust Gas Temperature (EGT), an open or shorted EGT harness, poor electrical connection in the EGT circuit, or extreme changes in ambient temperature soon after key ON, engine running. 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.

How can I visually inspect the related wiring harness and connectors to fix the P2429 fault code?

If you’re experiencing the P2429 fault code, which is indicated by the engine light or service engine soon warning light being on, there are a few things you can do to fix it. The cause of this issue could be a faulty Exhaust Gas Temperature (EGT), an open or shorted EGT harness, a poor electrical connection in the EGT circuit, or extreme changes in ambient temperature soon after key ON, engine running. To fix this, you should check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

What should I do if I find broken, bent, pushed out, or corroded connector’s pins while fixing the P2429 fault code?

If you find broken, bent, pushed out, or corroded connector’s pins while fixing the P2429 fault code, you should replace or repair the damaged pins. This is because faulty Exhaust Gas Temperature (EGT) harness or poor electrical connection can cause the engine light to turn on. Visually inspect the related wiring harness and connectors for any damage and replace or repair any damaged components. Checking for damaged pins is crucial as it can cause a poor electrical connection and lead to the same fault code.
