[SOLVED] P2670 Code: Low Actuator Supply Voltage – How To Fix

The P2670 fault code in automobiles refers to a problem with the transmission solenoids, which can cause the engine light to turn on.

The symptoms of this fault code include the service engine soon warning light turning on. The cause of this issue can be a faulty transmission solenoid, an open or shorted solenoid harness, a poor electrical connection in the solenoid circuit, or a faulty powertrain control module. The importance of repairing this issue lies in the fact that it can affect the performance of the transmission.

The repair difficulty is moderate, and it takes around 1.0 hour to fix.

To fix this issue, one needs to visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2670 fault code. Here are the symptoms to look out for:

  • The P2670 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 rough idling or stalling, and there may be a noticeable decrease in fuel efficiency.
  • Additionally, the transmission may fail to engage or disengage properly, and there may be a delay in the transmission’s response.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code P2670 can be caused by a range of issues, including faulty transmission solenoids and a faulty Powertrain Control Module (PCM).

  • The automobile fault code P2670 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.

To fix the p2670 fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code P2670, you need to check the possible causes listed above.
  • Inspect the wiring harness and connectors visually.
  • 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 P2670 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of diagnosis and fixing the P2670 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 P2670 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 P2670 code will be set for that solenoid. This code specifically refers to the Actuator Supply Voltage ‘B’ Circuit being low.

What are the possible causes of the P2670 automobile fault code?

If you’re experiencing the P2670 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 P2670 fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P2670 fault code, there are a few possible causes to consider. 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 the issue, start by visually inspecting the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

Is a faulty Powertrain Control Module (PCM) a common cause of the P2670 fault code?

While a faulty Powertrain Control Module (PCM) can be a possible cause of the P2670 fault code, it is not a common one. The most common cause of this code is faulty transmission solenoids, an open or shorted solenoid harness, or poor electrical connection in the 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.
