  • The P2771 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 harsh shifting, transmission slippage, decreased fuel efficiency, and decreased engine performance.
  • Additionally, the vehicle may experience difficulty shifting gears or may not shift gears at all.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code p2771 can be caused by a faulty switch, open or shorted harness, or poor electrical connection.

  • The automobile fault code P2771 can be caused by a faulty transfer case shift control switch.
  • It can also be caused by an open or shorted transfer case shift control switch harness.
  • Additionally, a poor electrical connection in the transfer case shift control switch circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code p2771, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p2771, 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 P2771 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 fixing the P2771 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P2771 code is related to the four-wheel drive low switch circuit in vehicles equipped with an active transfer case. It consists of the PCM, transfer case control module, and circuit wiring.

The transfer case control module controls the 4WD low signal on the low signal circuit. When the operator selects 4WD low, the transfer case control module grounds the signal circuit, and the 4WD low signal voltage on the circuit changes from ignition voltage to zero volts. The PCM then compensates for transfer case gear reduction in the transmission output shaft speed (OSS) sensor signal.

What are the possible causes of the P2771 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P2771 fault code. This code is caused by a faulty transfer case shift control switch, an open or shorted harness, or a poor electrical connection in the switch 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’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P2771 fault code?

If you’re experiencing the P2771 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may need to visually inspect the related wiring harness and connectors. This fault code is caused by a faulty Transfer Case Shift Control Switch, an open or shorted harness, or a poor electrical connection in the circuit. To fix the issue, check the possible causes listed above and inspect the wiring harness and connectors for any damage or corrosion. Look for broken, bent, pushed out, or corroded connector’s pins.
