P0796 Scion Code - Pressure Control Solenoid 'C' 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 'C' valve (Shift 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 P0796 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 P0796 Scion?
- Low transmission fluid level
- Dirty transmission fluid
- Faulty Pressure Control Solenoid 'C' valve (Shift Solenoid Valve SL3)
- Pressure Control Solenoid 'C' valve harness is open or shorted
- Pressure Control Solenoid 'C' valve circuit poor electrical connection
- Transmission valve body assembly is blocked
- Faulty Automatic transaxle assembly
How to Fix the DTC P0796 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 P0796 Scion Code
What does the OBDII code P0796 mean for a Scion?
P0796 indicates a performance issue with the pressure control solenoid 'C,' which regulates hydraulic pressure in the transmission for smooth shifting.
What are common symptoms of the P0796 code?
Symptoms may include harsh or erratic shifting, transmission slipping, reduced fuel efficiency, and the check engine light turning on.
What causes the P0796 code to appear?
Common causes include a faulty pressure control solenoid, low transmission fluid levels, contaminated transmission fluid, or internal transmission damage.
How can I diagnose the P0796 code?
Start by checking the transmission fluid level and condition, then inspect the pressure control solenoid and related wiring for damage or short circuits.
Can driving with the P0796 code damage my Scion?
Yes, driving with this code can cause further transmission damage and lead to costly repairs if not addressed promptly.
How do I fix the P0796 code?
Repairs may include replacing the faulty pressure control solenoid, flushing and refilling the transmission fluid, or repairing damaged wiring and connectors.
How much does it cost to fix a P0796 code?
Repair costs vary but typically range from $150 to $500, depending on whether the solenoid or fluid needs replacement and labor costs.
Can a dirty transmission filter cause the P0796 code?
Yes, a clogged or dirty transmission filter can restrict fluid flow, leading to solenoid performance issues and triggering the P0796 code.
Do I need to replace the transmission to fix the P0796 code?
Not necessarily. Most cases involve solenoid replacement or fluid maintenance rather than full transmission replacement.
What tools are needed to diagnose and repair the P0796 code?
You’ll need an OBDII scanner, a multimeter for electrical testing, and basic tools for accessing and replacing the solenoid or fluid.
