[SOLVED] P2685 Code: Low Actuator Supply Voltage – How To Fix

The P2685 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 transmission solenoid harness, a poor electrical connection in the transmission solenoid circuit, or a faulty PCM.

The importance of repairing this issue lies in the fact that it can lead to transmission failure.

The repair difficulty is moderate, and the repair time is estimated at 1.0 hour.

To fix the issue, one 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.

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the p2685 fault code. Here are the symptoms to look out for:

  • The P2685 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 reduced engine power, engine stalling, rough idling, and decreased fuel efficiency.
  • Additionally, the vehicle may experience difficulty starting, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

P2685 fault code can be caused by various factors such as faulty transmission solenoids, open circuits, and a faulty powertrain control module.

  • The automobile fault code P2685 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 automobile fault code p2685, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code P2685, 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 P2685 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 P2685 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P2685 fault 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 voltage returning from the solenoids through the ‘C’ circuit is low, the PCM will set the P2685 code.

This code indicates that there is an issue with the actuator supply voltage in the ‘C’ circuit, which could cause problems with the transmission solenoids.

It is important to have this issue diagnosed and repaired promptly to avoid further damage to the vehicle.

What are the possible causes of the automobile fault code P2685?

If you’re experiencing the engine light or service engine soon warning light with the fault code P2685, it could be due to a faulty transmission solenoid, an open or shorted transmission solenoid harness, a poor electrical connection in the transmission solenoid circuit, or a faulty powertrain control module (PCM). To fix the issue, check the possible causes listed above and visually inspect the related wiring harness and connectors for any damage or corrosion. Also, check for broken, bent, pushed out, or corroded connector pins.

How can one fix the P2685 fault code in their automobile?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light with a P2685 fault code, it could be due to faulty Transmission Solenoids, an open or shorted Transmission Solenoids harness, a poor electrical connection in the Transmission Solenoids circuit, or a faulty Powertrain Control Module (PCM). To fix this issue, visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

What should one visually inspect when trying to fix the P2685 fault code?

If you’re trying to fix the P2685 fault code, start by checking for an illuminated engine light or service engine soon warning light. The cause of this issue could be a faulty transmission solenoid, an open or shorted transmission solenoid harness, a poor electrical connection in the transmission solenoid circuit, or a faulty powertrain control module (PCM). To fix the problem, visually inspect the related wiring harness and connectors, checking for damaged components and looking for broken, bent, pushed out, or corroded connector pins.
