The P2519 fault code in automobiles indicates an issue with the low side pressure sensor circuit. This can be caused by low or excessive refrigerant, a faulty sensor, or poor electrical connections. The most common symptom is the illumination of the engine light or service engine soon warning light.

It is important to address this issue promptly as it can lead to further damage to the vehicle. The repair process involves visually inspecting the wiring harness and connectors for any damage or corrosion. The difficulty level of this repair is considered to be moderate, with an estimated repair time of 1.0 hour.

To interpret the fault code, it is recommended to check the possible causes listed above and visually inspect the related components.

Repair Importance Level3.33 (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 p2519 fault code. Here are the symptoms to look out for:

  • The P2519 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, difficulty in starting the engine, and poor acceleration.
  • The vehicle may also experience stalling or hesitation during acceleration.
  • Additionally, the transmission may not shift properly, and the vehicle may experience reduced fuel efficiency.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code P2519 can be caused by a range of issues, including low or excessive refrigerant and faulty pressure sensors.

  • The automobile fault code P2519 can be caused by low refrigerant levels, excessive refrigerant levels, a faulty low side pressure sensor, an open or shorted low side pressure sensor harness, and poor electrical connections in the low side pressure sensor circuit.

Below are the possible fixes for the automobile fault code p2519, including a visual inspection of related wiring harness and connectors.

  • To fix the automobile fault code p2519, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage or corrosion.
  • Look 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 P2519 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 diagnosis and fixing the P2519 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The P2519 code is related to the Air Condition (AC) system in a vehicle.

It indicates that there is an issue with the AC Request ‘A’ Circuit. The Powertrain Control Module (PCM) monitors the refrigerant pressure through the AC Pressure Sensor.

If the signal from the sensor is out of factory specifications, the PCM sets the OBDII code. This code can cause the AC system to malfunction and may result in a lack of cool air in the vehicle.

What are the possible causes of the automobile fault code P2519 that triggers the engine light or service engine soon warning light?

If you see the engine light or service engine soon warning light with the fault code P2519, it could be due to low or too much refrigerant, a faulty low side pressure sensor, or a poor electrical connection in the low side pressure sensor circuit. To fix this issue, check the possible causes mentioned above, visually inspect the wiring harness and connectors, and look for any damaged components or corroded connector pins.

How can one fix the P2519 fault code in an automobile, and what steps should be taken to ensure a successful repair?

If you’re experiencing the P2519 fault code in your automobile, which is indicated by the engine light being on, it could be due to low or too much refrigerant, a faulty low side pressure sensor, or a poor electrical connection in the low side pressure sensor circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

Is it possible for the P2519 fault code to reoccur after fixing the low refrigerant, too much refrigerant, faulty low side pressure sensor, low side pressure sensor harness, or poor electrical connection?

Although fixing the possible causes of the P2519 fault code, such as low refrigerant, too much refrigerant, faulty low side pressure sensor, low side pressure sensor harness, or poor electrical connection, can clear the engine light or service engine soon warning light, it is still possible for the fault code to reoccur. It is important 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 to ensure a complete fix.
