P0798 2008 Toyota Camry Code - Pressure Control Solenoid 'C' Electrical Valve SL3

Quick Answer

Shifting from 1st to 5th is performed in combination with ON and OFF operation of the shift solenoid valves SL1, SL2, SL3, S4 and SR which are controlled by the Engine Control Module (ECM). Common causes include Low transmission fluid level, Dirty transmission fluid, Faulty pressure control solenoid valve SL3. 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 P0798 2008 Toyota Camry Description

Shifting from 1st to 5th is performed in combination with ON and OFF operation of the shift solenoid valves SL1, SL2, SL3, S4 and SR which are controlled by the Engine Control Module (ECM). If an open or short circuit occurs in either of the shift solenoid valves, the ECM controls the remaining normal shift solenoid valves to allow the vehicle to be operated smoothly (Fail Safe Function).

Code Tech Notes

When a transmission solenoid is malfunctioned, 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 removing 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 P0798 2008 Toyota Camry 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 P0798 2008 Toyota Camry Code

What does the OBDII code P0798 mean for a 2008 Toyota Camry?

P0798 indicates an issue with the Pressure Control Solenoid 'C' (Valve SL3) circuit, suggesting an electrical fault that affects the transmission's hydraulic pressure regulation.

What are the common symptoms of code P0798 in a 2008 Toyota Camry?

Symptoms may include hard or erratic shifting, transmission slipping, failure to engage gears, and the Check Engine Light or transmission warning light turning on.

What causes the P0798 code to appear?

Common causes include a faulty Pressure Control Solenoid 'C', damaged or corroded wiring or connectors in the solenoid circuit, low transmission fluid, or internal transmission issues.

How do I diagnose the P0798 code on a 2008 Toyota Camry?

Diagnosis involves checking the transmission fluid level and condition, inspecting the wiring and connectors for damage, testing the solenoid's electrical resistance, and performing a scan tool test for live data.

Can a low transmission fluid level trigger the P0798 code?

Yes, low or contaminated transmission fluid can disrupt hydraulic pressure and contribute to triggering the P0798 code.

Is it safe to drive with the P0798 code active?

Driving with P0798 is not recommended as it can cause further transmission damage and lead to unsafe driving conditions due to shifting issues.

How is the P0798 code typically repaired?

Repairs may include replacing the faulty Pressure Control Solenoid 'C', repairing or replacing damaged wiring or connectors, flushing and refilling the transmission fluid, or addressing internal transmission problems.

What tools are needed to fix the P0798 code?

You may need an OBDII scanner, a multimeter for electrical testing, basic hand tools, and potentially a transmission fluid pump for fluid replacement.

How much does it cost to repair the P0798 code on a 2008 Toyota Camry?

Repair costs vary but can range from $200 to $500+ depending on whether the solenoid, wiring, or transmission fluid needs replacement. Internal transmission repairs can be more expensive.

Can ignoring the P0798 code damage my 2008 Toyota Camry?
