Error Code P2735: What It Means & What To Do?

<<See All OBD Codes

This is an OBD error code related to the pressure control solenoid of your vehicle. The P2735 error is defined as a Pressure Control Solenoid "F" Intermittent. Your vehicle has a Transmission Control Module which helps in shifting the gears smoothly so that you have a smooth and safe drive. The TCM will employ the Pressure Control Solenoids to be able to control the hydraulic pressure which is required to be able to apply the different clutch packs in the transmission. This helps in matching different gear ratios to propel the vehicle smoothly on road. If the TCM is able to detect an error with the Pressure Control Solenoid it will set the P2735 code.

The Pressure Control (PC) Solenoid Valve is basically an electronic pressure regulator which performs the task of controlling the transmission line pressure. It is done based on the current flow through the coil windings, when the current flow increases the magnetic field which is produced by the coil moves the plunger of the solenoid away from the exhaust port. When the exhaust port opens it decreases the output fluid pressure which is regulated by the PCM solenoid valve, this in turn will decrease the line pressure. The line pressure solenoid valve helps in regulating the oil pump discharge pressure as per the need of the driver. This is done in response to the signal sent from the TCM.

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

• The transmission fluid level is below the needed level
• There’s dirt in the transmission fluid
• Fault in the line pressure solenoid valve 'F'
• The harness of the Line pressure solenoid valve 'F' is either open or shorted
• Poor electrical connection is present at the Line pressure solenoid valve 'F' circuit

1. Pressure Control Solenoid - The PC solenoid is responsible for controlling the fluid pressure to the internal friction plate clutches/ drum bands. When the PC solenoid doesn’t work properly it can cause slipping, which can result in the transmission overheating. Don’t be stuck with a faulty Pressure Control Solenoid, fix it or buy a replacement on PartsAvatar and get rid of the P2735 code today!
2. Electronic Pressure Regulator - Maintain outlet pressure at the desired level, they do so with the help of a push valve and vent valve. There’s a small pressure sensor which monitors the output pressure and the set-point is maintained by the servo valves with the help of a digital or analog controller. A faulty regulator can cause trouble to your vehicle, fix the issue via repairs or opt for easy replacements from PartsAvatar. We offer free shipping on orders over $99.
3. Transmission Control Module - Is the module that controls the transmission of your vehicle. The TCM has to b in super working conditions so that your vehicle can change gears easily and move smoothly on the road. If you have found the problems with the TCM, try to repair them first and see if the P2735 code persists. If it does, then you will. have to go for replacement. Find the TCM fitment for your vehicle online on PartsAvatar. We ship to the remotest corners of Canada from our warehouses.
4. Powertrain Control Module - The brain of your vehicle which manages the functions of all the other solenoids and modules. The PCM has to work in top condition to avoid codes like P2735 to set. Try to repair the PCM first, as replacement may be pricey but also need reprogramming by a professional diagnostician. If you need a replacement look no further, we have a wide range of PCMs available for you on our website. Select from a vast range of prices to fit your budget.
5. Transmission Filter - This can become clogged with debris or even get damaged. You will need to replace it as it could have been the reason why the P2735 code was set in the first place. Find transmission filters on our website, and order from the comfort of your home and have them delivered to you in just a matter of days.
6. Transmission Pump - A faulty transmission pump may have caused the P2735 code to set. Find a resolution by fixing the damages to the pump, there may also be leakages or clogs in the pump. If that doesn’t help you will have to replace it.
7. Transmission Valve Body - This is known as the control center of the transmission. It has a maze of channels as well as passages which sends hydraulic fluid to the different valves. This in turn helps in gear changes. A problematic valve body can cause multiple issues, and harm the TCM. Try to repair and see if the P2735 code is corrected, if not you will have to go for replacement. PartsAvatar offers a wide range of the replacement transmission valve bodies. You can avail free shipping on orders over $99.

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2735 here:

Common Symptoms

• Vehicle is put into limp mode for safety
• The Transmission slips when trying to shift
• Overheating of the Transmission
• The Transmission catches in gear
• Lowered fuel economy
• Misfire-like symptoms are present
• The Check Engine Light is on

Have a look at some ways with which you can correct the P2735 code:

• Change the contaminated the fluid and damaged filter
• Repair or replace the faulty Pressure Control Solenoid
• Repair or replace the faulty transmission pump
• Repair or replace the defect in the transmission valve body
• Flush the in order to clean the passages
• Clean the corrosion present on the connectors
• Try to repair the damaged wiring or replace it if needed
• Flash or replace faulty PCM

To do all this, you will need a few high-quality auto parts such as pressure control solenoid valve, electronic pressure regulator, transmission control module, transmission filter, transmission pump, transmission valve body and so on. From where will you get them? From your local store? Well, why go there when you can order quality parts with us while sitting in the comfort of your home. So, just browse through our website and order your needed parts today.

Here are some steps which you should follow in order to diagnose this P2735 fault code:

The first step is to research the Technical Service Bulletins (TSB’s). For this you will have to match your vehicle’s year of manufacture, model and transmission. The reason why the TSB should be referred is mainly to save you time, and effort. It serves as a great tool during diagnosis.

Fluid check -Measure the level of fluid and also observe the condition of the fluid for any dirt or contamination. Don’t be hasty in changing the fluid, check the vehicle records to see when the fluid and filter change was done last. Depending on what you have found, you can proceed to changing the fluid or simply skip this step if the fluid level and purity is good.

Wiring inspection- Moving on to the wiring, perform a detailed visual examination and see if there are any damages present. Continue inspection of the connectors and see if the pins are corroded, bent or damaged. Check the wires and connectors going to the transmission pressure solenoids, transmission pump as well as the PCM. Depending on the type of vehicle the transmission pump may be driven electrically or mechanically. Fix all the issues you have found by conducting repairs or replacements as required.

Continuity Check- These will be done to figure out the problem if it wasn’t with the fuel, filter or electrical components. Continuity check is an advanced step, and hence will need certain tools like a digital multimeter and the specific technical references for the vehicle. Get hold of them and also all the troubleshooting information for your particular vehicle from the TSBs.

Voltage Check- To confirm the voltage and fluid pressure requirements you will need to refer the TSBs. In terms of continuity checks, they will usually be 0 ohms of resistance, but for safety refer your vehicles information source. When performing the continuity checks you have to ensure that power is removed from the circuit. This is important to avoid shorting the circuit and causing more damage to the vehicle. If you find that there is no continuity or resistance then that’s an indication that there is faulty wiring present which may be open or shorted and needs to be repaired/replaced.

Common Mistakes When Diagnosing the P2735 Code

• A problem with the Engine misfire
• Issue with the Transmission pump
• Presence of an Internal transmission problem
• Driveline Issue
