The P0987 code is an OBD-II trouble code that indicates a malfunction in the Transmission Fluid Pressure Sensor/Switch “E” Circuit. This code is crucial as it signals a potential issue in the transmission system that can affect vehicle performance.
What Does the P0987 Code Mean?
When the P0987 code is triggered, it indicates that the engine’s control module (PCM) or the Transmission Control Module (TCM) has detected a problem with the transmission fluid pressure sensor or its circuit. This sensor plays a vital role in ensuring smooth shifting of the transmission by managing hydraulic pressure.
What Causes the P0987 Code?
Several factors can lead to the P0987 code being set, including:
- Transmission Control Module (TCM) failure
- Low transmission fluid level
- Transmission fluid pressure sensor failure
- Wiring issues within the circuit
What Are the Symptoms of the P0987 Code?
Drivers may experience the following symptoms when the P0987 code is present:
- Transmission may not shift properly
- Increased fuel consumption
How Serious Is the P0987 Code?
The P0987 code is considered urgent, indicating that immediate action is necessary. Ignoring this code can lead to severe transmission damage and potentially compromise the safety of the vehicle, affecting both the driver and passengers.
How to Diagnose the P0987 Code
To effectively diagnose the P0987 code, follow these steps:
- Use an OBD-II scanner to confirm the P0987 code and check for any other related trouble codes.
- Inspect the transmission fluid level and condition; top off or replace if necessary.
- Examine the wiring and connectors associated with the Transmission Fluid Pressure Sensor for any signs of damage or corrosion.
- Test the transmission fluid pressure sensor to ensure it is functioning correctly.
- Check the TCM for any faults or failures.
Common Repairs for the P0987 Code
Repairs for the P0987 code may include:
- Replacing a faulty Transmission Fluid Pressure Sensor
- Repairing or replacing damaged wiring or connectors
- Refilling or changing the transmission fluid
- Replacing the Transmission Control Module if it is found to be defective
How Much Does It Cost to Fix the P0987 Code?
The cost to fix the P0987 code can vary widely based on the specific issue. Generally, repairs can range from $100 to $500, depending on whether you need to replace sensors, fix wiring, or address more significant transmission problems.
Can I Fix the P0987 Code Myself?
While some aspects of diagnosing and addressing the P0987 code can be performed by a knowledgeable DIYer, it is essential to understand that replacing sensors or modules without proper diagnostics may not resolve the underlying issue. If you’re not comfortable with automotive repairs, seeking professional assistance is advisable.
