P0985 Dodge Code - Shift Solenoid 'E' Control Circuit Low
Quick Answer
The P0985 diagnostic trouble code (DTC) for Dodge vehicles relates to the Shift Solenoid 'E' Control Circuit Low. Common causes include Faulty Shift Solenoid 'E': The shift solenoid itself may be malfunctioning, causing low voltage in the control circuit, Wiring issues: A short or open circuit in the control circuit, damaged connector, or corroded wiring can disrupt the flow of voltage to the shift solenoid, Faulty Transmission Control Module (TCM): A malfunctioning TCM can fail to send the correct signals to the shift solenoid, leading to low voltage issues. 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 P0985 Dodge Description
The P0985 diagnostic trouble code (DTC) for Dodge vehicles relates to the Shift Solenoid 'E' Control Circuit Low. This code indicates that there is an issue with the control circuit for Shift Solenoid 'E' in the transmission. The shift solenoid is responsible for controlling the flow of transmission fluid within the transmission, which in turn controls the shifting of gears. When the control circuit is detected as having low voltage, it means that the solenoid may not be able to function properly, leading to potential transmission problems.
Common Causes of P0985 Dodge
- Faulty Shift Solenoid 'E': The shift solenoid itself may be malfunctioning, causing low voltage in the control circuit.
- Wiring issues: A short or open circuit in the control circuit, damaged connector, or corroded wiring can disrupt the flow of voltage to the shift solenoid.
- Faulty Transmission Control Module (TCM): A malfunctioning TCM can fail to send the correct signals to the shift solenoid, leading to low voltage issues.
- Electrical problems: Issues with the vehicle's electrical system, such as a weak battery or alternator, can impact the control circuit's voltage levels.
Symptoms of P0985 Dodge
- Harsh or delayed shifting: The transmission may exhibit rough or delayed gear shifts, impacting the vehicle's overall performance and drivability.
- Erratic shifting patterns: The transmission may shift unpredictably, leading to inconsistent acceleration and deceleration.
- Failure to shift gears: The vehicle may struggle to change gears, resulting in limited speed range and potential safety concerns.
- Illuminated check engine light: The vehicle's onboard diagnostics system may trigger the check engine light to alert the driver of a potential issue in the transmission.
How to Fix P0985 Dodge
- Diagnose the issue: Use a scan tool to retrieve the specific DTC and perform a thorough inspection of the shift solenoid 'E' and its control circuit.
- Test the shift solenoid: Check the resistance and functionality of the shift solenoid to determine if it is operating within specifications.
- Inspect wiring and connectors: Examine the wiring harness and connectors for any signs of damage, corrosion, or loose connections. Repair or replace as necessary.
- Check the TCM: Test the transmission control module to ensure it is sending the correct signals to the shift solenoid. Replace if faulty.
- Clear the DTC: Once the issue has been resolved, clear the DTC from the vehicle's memory to reset the check engine light and monitor the transmission's performance.
Cost to Fix P0985 Dodge
The typical repair costs for addressing a Shift Solenoid 'E' Control Circuit Low issue can vary depending on the specific cause and the extent of the repairs needed. In general, the cost of replacing a shift solenoid 'E' can range from $150 to $300, including parts and labor. If additional wiring repairs or TCM replacement is required, the total cost may increase accordingly.
