[SOLVED] P2671 Code: High Voltage Fix For Actuator Supply Circuit

The P2671 automobile fault code indicates a problem with the transmission solenoids or the Powertrain Control Module (PCM). The most common symptom is the Engine Light ON or Service Engine Soon Warning Light.

The cause of this fault code could be a faulty transmission solenoid, an open or shorted solenoid harness, a poor electrical connection in the solenoid circuit, or a faulty PCM.

The importance of repairing this issue lies in the fact that it affects the transmission’s performance and can lead to further damage. The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins.

The repair time is estimated to be around 1.0 hour.

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the p2671 fault code. Here are the symptoms to look out for:

  • The P2671 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 a decrease in engine power, poor acceleration, and difficulty shifting gears.
  • The vehicle may also experience transmission slippage, harsh shifting, or even stalling.
  • Additionally, the car may have trouble starting or may not start at all.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code P2671 can be caused by a range of issues, including faulty transmission solenoids and a faulty Powertrain Control Module (PCM).

  • The automobile fault code P2671 can be caused by several factors.
  • These include faulty transmission solenoids, an open or shorted transmission solenoid harness, poor electrical connection in the transmission solenoid circuit, and a faulty Powertrain Control Module (PCM).
  • It is important to identify and address these causes promptly to prevent further damage to the vehicle.

Below are the possible fixes for the automobile fault code p2671, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P2671, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • 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 P2671 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 P2671 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P2671 code is related to the transmission solenoid circuits. The Powertrain Control Module (PCM) monitors these circuits by supplying voltage to the solenoids and checking for voltage returning from them. If the solenoid return circuit does not have the correct voltage returning to the PCM, the code for that solenoid will be set.

The P2671 code specifically refers to the Actuator Supply Voltage ‘B’ Circuit being high.

What are the possible causes of the P2671 automobile fault code?

If you’re experiencing the P2671 fault code, your engine light may be on. This could be due to a few different causes, including faulty transmission solenoids, an open or shorted transmission solenoid harness, a poor electrical connection in the transmission solenoid circuit, or a faulty powertrain control module. To fix the issue, it’s important to visually inspect the wiring harness and connectors, checking for any damaged components or broken, bent, pushed out, or corroded connector pins.

How can one visually inspect the related wiring harness and connectors to fix the P2671 fault code?

If you’re experiencing the P2671 fault code, which is indicated by the engine light or service engine soon warning light being on, there are a few possible causes. These include faulty transmission solenoids, an open or shorted transmission solenoids harness, poor electrical connection in the transmission solenoids circuit, or a faulty powertrain control module (PCM). 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.

Is a faulty Powertrain Control Module (PCM) a common cause of the P2671 fault code?

While a faulty Powertrain Control Module (PCM) can be a possible cause of the P2671 fault code, it is not a common one. The most common causes of this code are faulty transmission solenoids, an open or shorted transmission solenoid harness, or poor electrical connections in the transmission solenoid circuit. To fix the issue, one should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.
