Code P0980 Toyota Description
The P0980 diagnostic trouble code (DTC) for Toyota vehicles indicates a problem with the Shift Solenoid 'C' control circuit being too high. In an automatic transmission system, shift solenoids are responsible for controlling the flow of transmission fluid to engage or disengage gears. Solenoid 'C' specifically deals with a particular gear ratio within the transmission. When the control circuit for this solenoid is detected to have a high voltage, it means that there is an electrical issue affecting the solenoid's operation.
Common Causes of P0980 Toyota
- Faulty shift solenoid 'C'
- Damaged wiring or connectors in the control circuit
- Low transmission fluid levels or dirty fluid
- Electrical issues such as a short circuit or corrosion
- Malfunctioning transmission control module (TCM)
Symptoms of P0980 Toyota
- Harsh or delayed shifting
- Transmission slipping
- Inability to shift gears
- Limp mode activation
- Illumination of the check engine light
How to Fix P0980 Toyota
- Begin by conducting a visual inspection of the wiring and connectors in the Shift Solenoid 'C' control circuit to check for any visible damage or corrosion.
- Test the shift solenoid 'C' using a multimeter to determine if it is functioning correctly. If it is faulty, replace the solenoid.
- Check the transmission fluid level and condition. If it is low or dirty, perform a transmission fluid flush and refill.
- Inspect the TCM for any signs of damage or malfunction. Test the TCM to ensure proper operation and replace if necessary.
- Clear the diagnostic trouble codes from the vehicle's computer using a scan tool and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P0980 Toyota
The typical repair costs for addressing a P0980 code in a Toyota vehicle can range from $200 to $600, depending on the specific cause of the issue and the cost of parts and labor. This estimate includes the cost of a new shift solenoid 'C,' transmission fluid flush, TCM replacement (if needed), and diagnostic labor charges. However, it is essential to note that labor rates at auto repair shops can vary widely, so it is advisable to obtain quotes from multiple shops to ensure a competitive price.
