P2808 2016 Toyota RAV4 Code - Pressure Control Solenoid 'G' Performance

Quick Answer

Changing from 1st to 6th is performed by the Engine Control Module (ECM) turning shift solenoid valves SL1, SL2, SL3, SL4, and SL on and off. Common causes include Low transmission fluid level, Dirty transmission fluid, Faulty Pressure Control Solenoid 'G' valve (Shift Solenoid Valve SL4). Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2808 2016 Toyota RAV4 Description

Changing from 1st to 6th is performed by the Engine Control Module (ECM) turning shift solenoid valves SL1, SL2, SL3, SL4, and SL on and off. If an open or short circuit occurs in any of the shift solenoid valves, the ECM controls the remaining normal shift solenoid valves to allow the vehicle to be operated.
The ECM commands gear shifts by turning the shift solenoid valves on and off. According to the input shaft speed, intermediate (counter) shaft speed, and output shaft speed, the ECM detects the actual gear (1st, 2nd, 3rd, 4th, 5th or 6th gear). When the gear commanded by the ECM and the actual gear are not the same, the ECM illuminates the MIL and stores the Diagnostic Trouble Code (DTC).

Code Tech Notes

When a transmission solenoid malfunction, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is dirty, it's recommended to change the transmission fluid and if possible, remove the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a mechanical transmission failure, and that the transmission will need to be rebuilt or replaced.

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the P2808 2016 Toyota RAV4 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P2808 2016 Toyota RAV4 Code

1. What does OBDII code P2808 mean on a 2016 Toyota RAV4?

P2808 indicates an issue with the performance of the Pressure Control Solenoid 'G' in the transmission, which regulates hydraulic pressure for proper gear shifting.

2. What are the common symptoms of code P2808 in a 2016 Toyota RAV4?

Symptoms may include harsh or delayed gear shifts, transmission slipping, poor fuel efficiency, or the Check Engine Light illuminated.

3. What causes the P2808 code to appear in a 2016 Toyota RAV4?

Common causes include a faulty pressure control solenoid, low or dirty transmission fluid, electrical issues such as damaged wiring or connectors, or a malfunctioning transmission control module (TCM).

4. Can low transmission fluid trigger the P2808 code?

Yes, low or degraded transmission fluid can cause the pressure control solenoid to perform poorly, leading to this error code.

5. How do I diagnose the P2808 code on my 2016 Toyota RAV4?

Start by checking the transmission fluid level and condition, inspecting the solenoid wiring and connectors, and using a scan tool to test the solenoid's performance.

6. Can I drive my 2016 Toyota RAV4 with the P2808 code?

Driving with this code is not recommended, as it can lead to further damage to the transmission and potential safety issues due to erratic shifting.

7. How is the P2808 code fixed in a 2016 Toyota RAV4?

Repairs may include replacing the pressure control solenoid, flushing and refilling the transmission fluid, repairing damaged wiring, or reprogramming or replacing the TCM if necessary.

8. How much does it cost to repair the P2808 code on a 2016 Toyota RAV4?

The cost depends on the issue but typically ranges from $200 to $600 for solenoid replacement, plus additional costs if transmission fluid service or electrical repairs are needed.

9. Can a dirty transmission filter cause the P2808 code?

Yes, a clogged transmission filter can restrict fluid flow, affecting the solenoid's performance and triggering this code.

10. Do I need to replace the entire transmission to fix the P2808 code?

In most cases, replacing the solenoid, addressing electrical issues, or servicing the transmission fluid resolves the issue without requiring a full transmission replacement.
