Code P0788 Scion Description
The P0788 code for Scion vehicles indicates an issue with the Shift/Timing Solenoid High. This code is typically found in automatic transmission vehicles and points to a problem with the shift solenoid or its circuit. The shift solenoid is responsible for controlling the flow of transmission fluid, which in turn, regulates the shifting of gears in the transmission. When the solenoid is stuck in the high position, it can lead to a variety of transmission issues and affect the vehicle's overall performance.
Common Causes of P0788 Scion
- Faulty shift solenoid
- Damaged wiring or connectors in the solenoid circuit
- Low transmission fluid levels
- Clogged transmission filter
- Internal transmission damage
Symptoms of P0788 Scion
- Erratic shifting or failure to shift gears
- Harsh shifting or jerking movements while driving
- Transmission slipping or getting stuck in a specific gear
- Decreased fuel efficiency
- Illumination of the Check Engine Light
How to Fix P0788 Scion
- Diagnose the issue by connecting a diagnostic scanner to retrieve the trouble codes and perform a thorough inspection of the transmission system.
- Inspect the shift solenoid and its wiring for any signs of damage or corrosion. Replace the shift solenoid if necessary.
- Check the transmission fluid level and condition. Top off or replace the transmission fluid as needed.
- Inspect the transmission filter for any debris or clogs. Replace the filter if necessary.
- Clear the trouble codes from the vehicle's computer and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0788 Scion
The cost of repairing the Shift/Timing Solenoid High issue can vary depending on the extent of the damage and the specific cause of the problem. On average, the parts for a shift solenoid replacement can range from $100 to $300, while the labor costs can range from $150 to $300. Overall, the total repair cost for this issue can range from $250 to $600 or more. It is important to keep in mind that these are rough estimates, and actual repair costs may vary based on the vehicle's make and model, as well as the location and labor rates of the auto repair shop. It is recommended to consult with a professional mechanic to get an accurate cost estimate for repairing the P0788 code on a Scion vehicle.
