P2808 Scion 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 Scion Description
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).
What are the Possible Causes of the DTC P2808 Scion?
- Low transmission fluid level
- Dirty transmission fluid
- Faulty Pressure Control Solenoid 'G' valve (Shift Solenoid Valve SL4)
- Pressure Control Solenoid 'G' valve harness is open or shorted
- Pressure Control Solenoid 'G' valve circuit poor electrical connection
- Transmission valve body assembly is blocked
- Faulty Automatic transaxle assembly
How to Fix the DTC P2808 Scion?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P2808 Scion Code
1. What does the OBDII code P2808 mean on a Scion?
P2808 indicates a performance issue with Pressure Control Solenoid 'G' in the transmission, which helps regulate hydraulic pressure for smooth gear shifts.
2. What are common symptoms of code P2808 in a Scion?
Symptoms include harsh or delayed gear shifts, slipping transmission, poor fuel economy, and potentially the check engine light turning on.
3. What causes the P2808 code in a Scion?
Common causes include a faulty pressure control solenoid, transmission fluid issues (low or dirty fluid), wiring problems, or internal transmission damage.
4. How can I diagnose the P2808 code on my Scion?
Start by checking the transmission fluid condition and level, inspecting the wiring and connectors for damage, and testing the pressure control solenoid for proper function.
5. Can I still drive my Scion with the P2808 code?
Driving with this code is not recommended as it may lead to further transmission damage or unsafe driving conditions due to erratic gear shifting.
6. How do I fix the P2808 code on my Scion?
Repairs may include replacing the pressure control solenoid, flushing and refilling the transmission fluid, repairing damaged wiring, or addressing internal transmission issues.
7. How much does it cost to fix the P2808 code?
Repair costs vary depending on the issue but typically range from $200-$600 for solenoid replacement and transmission fluid service. Internal transmission repair can be more expensive.
8. Can dirty transmission fluid trigger the P2808 code in a Scion?
Yes, dirty or degraded transmission fluid can cause solenoid performance issues, leading to this code.
9. How do I prevent the P2808 code from occurring on my Scion?
Regular transmission maintenance, including fluid changes and inspections, can help prevent solenoid and transmission performance issues.
10. Is P2808 specific to Scion vehicles?
No, P2808 can appear on other vehicle makes and models that use pressure control solenoids in their transmissions, but repair procedures may vary.
