P0980

2017-10-10

Description:

  • The fault code P0980 indicates a high voltage condition in the control circuit of shift solenoid 'C' in the transmission. The shift solenoids are responsible for controlling the engagement and disengagement of specific gears in the transmission. A high voltage in the control circuit of shift solenoid 'C' can result in improper gear shifting, erratic shifting behavior, or transmission performance issues.

Possible Symptoms:

  • Improper or erratic gear shifting.

  • Delayed or prolonged shifting between gears.

  • Slipping or inability to engage certain gears.

  • Malfunction Indicator Lamp (MIL) or Check Engine Light illuminated.

  • Limited or no communication with the TCM through diagnostic tools.

  • Other associated transmission

  • related fault codes may be present.

  • No noticeable drivability issues are typically associated with this fault code.

Possible Causes:

  • Faulty shift solenoid 'C'

  • Wiring or electrical connection issues in the control circuit of shift solenoid 'C'

  • Malfunctioning transmission control module (TCM)

  • Short circuit to power in the control circuit

  • High battery voltage

Related Parts:

  • Shift Solenoid: It helps to change gears in automatic transmission cars. A bad solenoid causes difficulty in shifting gears

Possible Solutions:

  • Inspect the wiring and electrical connections in the control circuit of shift solenoid 'C' for any damage, loose connections, or corrosion. Repair or replace as necessary.

  • Test and replace the faulty shift solenoid 'C', if necessary.

  • Verify the functionality of the transmission control module (TCM). Replace if it is defective.

  • Check for any short circuits to power in the control circuit and repair as needed.

  • Ensure the battery voltage is within the specified range. If it is too high, investigate and resolve the underlying issue.
