[SOLVED] P2730 Code: High Control Circuit – Fix Your Pressure Solenoid Now!

The P2730 fault code in automobiles refers to a problem with the line pressure solenoid valve ‘E’ circuit. This issue can cause the engine light to turn on, indicating a problem with the transmission fluid level, dirty transmission fluid, or a faulty solenoid valve.

It is important to address this issue promptly as it can lead to further damage to the transmission. The repair process involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken or corroded connector pins. The repair time for this issue 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 p2730 fault code.

Here are the symptoms to look out for:

  • The P2730 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 starting or may stall while driving.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code P2730 can be caused by various factors such as low transmission fluid level, dirty transmission fluid, and faulty line pressure solenoid valve ‘E’.

  • The automobile fault code P2730 can be caused by a low transmission fluid level.
  • It can also be caused by dirty transmission fluid.
  • Another cause of this fault code is a faulty line pressure solenoid valve ‘E’.
  • Additionally, the line pressure solenoid valve ‘E’ harness being open or shorted can cause this fault code.
  • Lastly, a poor electrical connection in the line pressure solenoid valve ‘E’ circuit can also be a cause of the P2730 fault code.

Below are the possible fixes for the automobile fault code p2730, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P2730, first, check the possible causes listed above.
  • Then, 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 P2730 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 diagnosis and fixing the P2730 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P2730 code refers to a problem with the Pressure Control (PC) Solenoid Valve in the transmission system of a vehicle. The PC Solenoid Valve is responsible for regulating the transmission line pressure based on the current flow through its coil windings.

When the PC Solenoid Valve is not functioning properly, it can cause the transmission line pressure to be too high, resulting in issues with shifting and overall performance of the vehicle.

What are the possible causes of the P2730 fault code?

If you see the engine light on or service engine soon warning light, it could be due to the P2730 fault code. This code is often caused by low transmission fluid level, dirty transmission fluid, faulty line pressure solenoid valve ‘E’, or a poor electrical connection in the line pressure solenoid valve ‘E’ circuit. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for any damaged components or corroded connector pins.

How can I fix the P2730 fault code?

If you’re experiencing the P2730 fault code, indicated by the engine light or service engine soon warning light, it could be due to low transmission fluid level, dirty transmission fluid, a faulty line pressure solenoid valve ‘E’, or a poor electrical connection in the line pressure solenoid valve ‘E’ circuit. To fix this issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for any damaged components or corroded connector pins.

What should I visually inspect to troubleshoot the P2730 fault code?

If you’re experiencing the P2730 fault code, indicated by the engine light or service engine soon warning light turning on, 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. This fault code can be caused by low transmission fluid level, dirty transmission fluid, faulty line pressure solenoid valve ‘E’, or a poor electrical connection in the line pressure solenoid valve ‘E’ circuit.

p2730 error fault code explained

If you see the Engine Light ON (or Service Engine Soon Warning Light) and the fault code is p2730, check the transmission fluid level and condition.

Also, inspect the line pressure solenoid valve ‘E’ and its harness for any damage or poor electrical connection.
