If you’re experiencing an illuminated Engine Light or Service Engine Soon Warning Light, it could be due to the P2027 fault code.

This code indicates a problem with the Natural Vacuum Leak Detection (NVLD) module, which could be faulty or have a poor electrical connection. Additionally, the NVLD module harness may be open or shorted, or there could be a problem with the Powertrain Control Module (PCM).

The repair time for this fault code is estimated at 1.0, and it’s important to visually inspect the wiring harness and connectors for any damage or corrosion.

To interpret the fault code, check the “Possible Causes” listed above and follow the recommended fix.

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 p2027 fault code.

Here are the symptoms to look out for:

  • The P2027 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, rough idling, stalling, and poor acceleration.
  • The vehicle may also experience misfires, reduced fuel efficiency, and difficulty starting.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

P2027 fault code can be caused by a faulty NVLD module, open or shorted NVLD module harness, poor electrical connection, or a faulty PCM.

  • The automobile fault code P2027 can be caused by a faulty Natural Vacuum Leak Detection (NVLD) module.
  • It can also be caused by an open or shorted NVLD module harness.
  • Another cause can be a poor electrical connection in the NVLD module circuit.
  • Lastly, a faulty Powertrain Control Module (PCM) can also trigger this fault code.

To fix the p2027 fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p2027, 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.
  • Ensure that all the connections are secure and free of corrosion.
  • This repair should take approximately 1.0 hour.

The fault code P2027 indicates a problem with the evaporative emission control system. The most common causes of this code are a faulty fuel cap, a leak in the fuel tank or fuel lines, or a malfunctioning purge valve. The estimated repair time for this code is 1.0 hour, and the cost of fixing it can range from $75 to $150 per hour depending on the auto repair shop.

Other factors that may affect the cost include the severity of the problem, the type of vehicle, and the location of the repair shop.

The P2027 code is related to the Evaporative Emissions Fuel Vapor Temperature Sensor Circuit. The Powertrain Control Module (PCM) monitors the Natural Vacuum Leak Detection (NVLD) module input for expected NVLD ambient temperature sensor values. If the input is outside a calibrated set of limits, the P2027 code sets.

This code indicates that the fuel vapor temperature sensor circuit is experiencing high voltage.

What are the possible causes of the P2027 automobile fault code?

If you’re experiencing the P2027 fault code, your engine light may be on. This could be due to a faulty Natural Vacuum Leak Detection (NVLD) module, an open or shorted NVLD module harness, a poor electrical connection in the NVLD module circuit, or a faulty Powertrain Control Module (PCM). To fix the issue, 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 pins.
