What Does the P0985 Code Mean?
The P0985 code is an OBD-II trouble code that indicates a problem with the Shift Solenoid “E” control circuit. This code is set when the Transmission Control Module (TCM) detects that the shift solenoid is not operating as expected, which can affect the transmission’s ability to shift properly.
What Causes the P0985 Code?
- Transmission Control Module (TCM) failure
- Low transmission fluid level
- Failure of the transmission shift solenoid
- Wiring or connector issues in the circuit
What Are the Symptoms of the P0985 Code?
- Transmission may not shift properly
- Increased fuel consumption
How Serious Is the P0985 Code?
The P0985 code is considered urgent because it can lead to severe transmission damage or create unsafe driving conditions. If this code is triggered, immediate attention is required to prevent further complications.
How to Diagnose the P0985 Code
To diagnose the P0985 code, a mechanic will typically follow these steps:
- Use an OBD-II scanner to confirm the P0985 code and check for any additional codes.
- Inspect the transmission fluid level and condition.
- Examine the wiring and connectors associated with the shift solenoid.
- Test the shift solenoid’s functionality and its connection to the TCM.
- Check the TCM for proper operation.
Common Repairs for the P0985 Code
- Replacing the shift solenoid
- Repairing or replacing damaged wiring or connectors
- Refilling or replacing the transmission fluid
- Replacing the Transmission Control Module if necessary
How Much Does It Cost to Fix the P0985 Code?
The cost to repair the P0985 code can vary significantly based on the underlying issue. Basic repairs, like changing the shift solenoid or fluid, can range from $100 to $300. However, if the TCM needs replacement, the cost can rise to $1,000 or more, including parts and labor.
Can I Fix the P0985 Code Myself?
While some DIY enthusiasts may tackle minor repairs like checking fluid levels or replacing a shift solenoid, diagnosing and repairing the P0985 code requires a good understanding of automotive systems and access to specialized tools. If you are unsure, it is advisable to consult a professional mechanic to ensure proper diagnosis and repair.
