Error Code P2739: What It Means & What To Do?

<<See All OBD Codes

This OBD-II error code is related to a problem with the Pressure Control Solenoid of your vehicle and hence is defined as a Pressure Control Solenoid "F" Control Circuit High. Your vehicle's Transmission Control Module makes use of the PC solenoids so that it can control the hydraulic pressure. This hydraulic pressure is what helps in applying various clutch packs so that gear ratios can be applied as per the need of the driver. All this works cohesively to give a smooth drive on the road. If the TCM picks up a problem with the pressure control solenoid it will set the P2739 code and the engine will likely enter limp mode and the check engine light will be turned on as well.We have gathered all the information needed for you to understand this error better at the same time be able to figure out how to resolve the problem, so that you can use your car.

The PC solenoid valve is primarily an electronic pressure regulator. This controls the transmission line based on current flowing through its coil windings. When this current flow and increases a magnetic field is then produced. This in turn moves the solenoids plunger away from the exhaust port, which decreases the output fluid pressure. This output fluid pressure is regulated by the PC solenoid valve, and hence the line pressure is ultimately lowered. In order to suit the driving condition in response to the signal received by the TCM module, the line pressure solenoid valve will regulate the oil pump discharge pressure.

What causes this problem with the Pressure Control Solenoid "F" Control Circuit High?

• Defects of the Pressure Control Solenoid
• Dirty or contaminated transmission fluid
• Transmission filter is dirty or clogged
• Corrosion or damages of the connectors
• Defect in the Transmission Pump
• Defects present in the Transmission Valve Body
• Restrictions in the hydraulic passages
• Problems in the wiring, possible damages also present
• Non-functional PCM module

1. Pressure Control Solenoid - Controls the fluid pressure to the internal friction plate clutches or drum bands. If the PC solenoid is not working properly it can cause slipping, this causes the transmission to overheat. Fix this problem and get rid of the P2739 code by repairing or replacing the PC solenoid. PartsAvatar stocks over 3 million car replacement parts, you are bound to find the PC solenoid for your vehicle online with us.
2. Transmission Control Module - Changes the gears so that the vehicle can function on road. A TCM fault can very much cause error code P2739 to set. In order to fix this issue, you will have to either repair or replace the TCM. Find the perfect fitment TCM for your vehicle today on PartsAvatar. Order online from the comfort of your home and have it reach your doorstep in just days!
3. Oil Pump - Responsible for circulating the engine oil under pressure to the rotating bearings, the sliding pistons and the camshaft of the engine. This process helps lubricate the bearings and thereby allows use of higher-capacity fluid bearings and also assists in cooling the engine. A fault pump can be the reason why you have the P2739 code set. Fix this problem via repairs and see if the code persists, if it does; then you will have to opt for replacement. You can choose from a wide range of brands and prices to get the one suiting your budget and quality. PartsAvatar ships to the remotest corners of Canada. Now you can skip cross border shipping and delays in delivery!
4. Pressure Control Solenoid Valve - The fluid pressure to the internal friction plate clutches or drum bands of your vehicle is controlled by this valve. A bad or failing transmission pressure control solenoid can cause multiple issues like slipping, which causes the transmission to heat up. You will also note the P2739 code to set due to a faulty PC solenoid valve. Try to fix the problem by repairs or replacement as needed.
5. Transmission Pump - Helps in circulating the fluid. A faulty pump can harm the whole TCM. Try to fix the problem via repairs or replace it as needed.
6. Powertrain Control Module - Is the central control unit of your vehicle, it manages all the other modules so that your car functions smoothly. A problematic PCM can result in random codes to be set, so try to fix it first. If that doesn’t help you will have to replace it. Replacing the PCM requires reprogramming. Ensure you take help from a professional diagnostician for this. Find what you’re looking for on PartsAvatar and avail free shipping on orders over CAD $99.
7. Transmission Valve Body - An integral part of the TCM, the Transmission valve body works in a network system. It directs pressurized transmission fluid to a network of valves which put together correct clutch packs for smooth gear functioning. You will have to resolve the issue with the transmission valve body to get rid of the P2739 code. You can find one on PartsAvatar, order online and track your shipment till it reaches your doorstep.

If you are facing OBD error code P2739, then there are significant common symptoms that can be felt or observed. We have worked out a list here to help you out in understanding this problem better.

Common Symptoms

• Misfire-like symptoms are present
• Check Engine Light gets activated
• Increase in the consumption of fuel as compared to before
• PCM puts the vehicle into limp mode
• A slip of Transmission when shifting becomes common
• It is hard to shift transmission

After understanding the symptoms and few common causes behind the OBD error code, we are here to help you out in understanding the ways and means to correct the issue. To solve any issue you need to follow certain steps, and to solve OBD error code P2739, you will need to undergo the following replacements:

• Change the fluid and filter
• Replace faulty Pressure Control Solenoid or repair it if possible
• The faulty transmission pump will have to undergo repairs or replacement
• Transmission valve body needs to be repaired or replacement as needed
• Flush the transmission so that the passages can be cleaned of any blockages
• Cleaning of all the corrosion from connectors and checking wiring/ circuitry for damages
• PCM needs Flashing or replacing

If you need parts to fix this issue, you no longer need to search for them. We at PartsAvatar Canada have an extensive range of auto parts Pcm, Pressure Control Solenoid, Transmission Control Module, Transmission Valve Body, Transmission Pump, Transmission Filter, Oil Pump in stock from you, ranging from all replacement parts to all interior and exterior parts

Diagnosing this code is important so that you can drive your vehicle safely on road. In order for the PCM to get the car out of limp mode you will have to fix the issues you’re having with it and get rid of the P2739 code. Following are some steps to do so:

Use the OBD scanner and connect it to the diagnostic port of your vehicle and retrieve all the codes stored. Make note of them just in order just in case there’s an intermittent condition. Now take your vehicle on a test drive and see if the code is reset or if the PCM enters readiness mode. This will help to know if there’s an intermittent condition.

Depending on the condition of the transmission you may have to removing the transmission pan by removing it and examining its condition. This will help resolve any fuel related issues with the transmission.

It’s important to also check the wiring and connectors to see what condition they are in. Accordingly repair or replace it and see if the code returns. After these are fixed clear the codes and go on a test drive and see if the code reappears.

Common Mistakes When Diagnosing the P2739 Code

• Failed Transmission Control Module (TCM)
• Low level of the Transmission fluid
• Failure of the Transmission shift solenoid
• Problems with the wiring
