Code P2735 Description

The Pressure Control (PC) Solenoid Valve an electronic pressure regulator that controls transmission line pressure based on current flow through its coil windings. As current flow is increased, the magnetic field produced by the coil moves the solenoid’s plunger further away from the exhaust port. Opening the exhaust port decreases the output fluid pressure regulated by the PC solenoid valve, which ultimately decreases line pressure. The line pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in response to a signal sent from the Transmission Control Module (TCM).

Frequently Asked Questions about P2735 Code

1. What does the OBDII code P2735 mean?

P2735 indicates an intermittent issue with the pressure control solenoid "F," which regulates hydraulic pressure in the transmission for smooth gear shifting.

2. What are the common symptoms of the P2735 code?

Symptoms include harsh or delayed shifting, transmission slippage, decreased fuel efficiency, and in some cases, the vehicle entering limp mode.

3. What causes the P2735 code to trigger?

Possible causes include a faulty pressure control solenoid, low or contaminated transmission fluid, damaged wiring or connectors, or an issue with the transmission control module (TCM).

4. Can I drive with the P2735 code active?

Driving with this code is not recommended, as it can lead to transmission damage or unsafe driving conditions due to erratic shifting.

5. How do I diagnose the P2735 code?

Diagnosis involves checking the transmission fluid level and condition, inspecting wiring and connectors for damage, and testing the pressure control solenoid and related circuits.

6. How is the P2735 code typically fixed?

Repairs may involve replacing the faulty pressure control solenoid, repairing damaged wiring, cleaning or replacing the transmission fluid, or updating/replacing the TCM.

7. Could low transmission fluid cause the P2735 code?

Yes, low or contaminated transmission fluid can cause hydraulic pressure issues, leading to the P2735 code.

8. How much does it cost to fix the P2735 code?

Repair costs vary, but replacing a pressure control solenoid typically costs between $200 and $500, depending on labor and parts.

9. Will clearing the P2735 code with a scanner fix the issue?

Clearing the code without addressing the root cause is a temporary solution, and the issue will likely return.

10. Can a bad TCM cause the P2735 code?

Yes, a malfunctioning transmission control module can fail to properly control the pressure solenoid, triggering the code.
