If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1e09 fault code.

Here are the symptoms to look out for:

  • The P1E09 fault code in an automobile 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, rough idling, stalling, and difficulty starting the engine.
  • Additionally, the vehicle may experience transmission shifting issues, and there may be a noticeable decrease in overall performance.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The P1E09 fault code in automobiles can be caused by various factors, including issues with the fuel delivery system, ECT sensor, MAP sensor, O2 sensor, engine mechanics, and PCM.

  • The automobile fault code P1E09 can be caused by various factors.
  • These include issues with the fuel delivery system, a faulty Engine Coolant Temperature (ECT) Sensor, a faulty Manifold Absolute Pressure (MAP) Sensor, a faulty Oxygen (O2) Sensor, engine mechanical problems, and a faulty Powertrain Control Module (PCM).
  • It is important to identify the specific cause of the fault code to ensure proper diagnosis and repair.

Below are the possible fixes for the automobile fault code p1e09, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P1E09, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any 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 P1E09 indicates an issue with the hybrid battery pack coolant pump.

The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour.

Other factors that may influence the cost include the location of the shop, the type of vehicle, and the severity of the issue.

The P1E09 code is related to the Oxygen (O2) Sensor in the automobile. The Powertrain Control Module (PCM) monitors the O2 Sensor and sets the code when it is not to factory specifications. The code specifically indicates that Closed Loop Fueling has not been achieved in Bank 1 Downstream.

This fault code can cause issues with the fuel efficiency and emissions of the vehicle. It is important to have this code diagnosed and repaired by a qualified mechanic to ensure proper functioning of the vehicle.

What are the possible causes of the P1E09 fault code?
