P2759 Scion Code - Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical
Quick Answer
The Engine Control Module (ECM) uses the signals from the throttle position sensor, airflow meter, input turbine speed sensor, output speed sensor, and crankshaft position sensor to monitor the engagement condition of the lock-up clutch. Common causes include Faulty Torque Converter Clutch Pressure Control Solenoid (Shift Solenoid Valve SLU), Torque Converter Clutch Pressure Control Solenoid harness is open or shorted, Torque Converter Clutch Pressure Control Solenoid circuit poor electrical connection. 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 P2759 Scion Description
The ECM compares the engagement condition of the lock-up clutch with the lock-up schedule in the ECM memory to detect mechanical problems of the shift solenoid valve (SLU), valve body, and torque converter.
When an open or short in the shift solenoid valve SLU circuit is detected, the ECM determines there is a malfunction. The ECM will turn on the MIL and store the Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P2759 Scion?
- Faulty Torque Converter Clutch Pressure Control Solenoid (Shift Solenoid Valve SLU)
- Torque Converter Clutch Pressure Control Solenoid harness is open or shorted
- Torque Converter Clutch Pressure Control Solenoid circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P2759 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.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P2759 Scion 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 P2759 Scion Code
What does the OBDII code P2759 mean for a Scion?
P2759 indicates an issue with the Torque Converter Clutch Pressure Control Solenoid Circuit, specifically an electrical problem affecting the solenoid's function in the transmission system.
What are the symptoms of code P2759 in a Scion?
Common symptoms include poor fuel efficiency, transmission slipping, delayed shifting, rough or harsh shifts, and the Check Engine Light turning on.
What causes the P2759 code to appear in a Scion?
Possible causes include a faulty torque converter clutch solenoid, damaged wiring or connectors, a malfunctioning transmission control module (TCM), or low transmission fluid levels.
Can low transmission fluid cause a P2759 code in a Scion?
Yes, low or dirty transmission fluid can cause poor hydraulic pressure, leading to solenoid malfunction and triggering the P2759 code.
How do I diagnose the P2759 code on my Scion?
Start by checking transmission fluid levels and condition, inspecting wiring and connectors for damage, and testing the torque converter clutch solenoid for proper operation.
Is it safe to drive with the P2759 code on my Scion?
Driving with this code is not recommended, as it can lead to transmission damage, reduced performance, and increased fuel consumption if left unaddressed.
How much does it cost to fix the P2759 code in a Scion?
Repair costs vary depending on the issue but may range from $150 to $500 for solenoid replacement and higher if additional transmission repairs are needed.
Can a faulty TCM cause the P2759 code in a Scion?
Yes, a malfunctioning Transmission Control Module (TCM) can fail to regulate the solenoid properly, leading to the P2759 code.
How can I prevent the P2759 code from occurring?
Regular maintenance, including timely transmission fluid changes and inspections for wiring or connector damage, can help prevent this code.
Does the P2759 code require a transmission rebuild in a Scion?
Not necessarily. In many cases, the issue can be resolved by replacing the solenoid, repairing wiring, or addressing fluid-related problems without a full rebuild.
