The P0995 OBD-II code indicates an issue with the Transmission Fluid Pressure Sensor/Switch “F” Circuit, which is crucial for the proper functioning of a vehicle’s transmission system.
What Does the P0995 Code Mean?
The P0995 code is triggered when the Transmission Control Module (TCM) or Powertrain Control Module (PCM) detects a high signal from the transmission fluid pressure sensor or switch “F”. This sensor is responsible for monitoring the hydraulic fluid pressure within the transmission, which is essential for smooth shifting and overall transmission performance.
What Causes the P0995 Code?
Several factors can lead to the P0995 code being set, including:
- Failure of the Transmission Control Module (TCM)
- Low transmission fluid levels
- Malfunction of the transmission fluid pressure sensor
- Wiring issues affecting the sensor’s electrical circuit
What Are the Symptoms of the P0995 Code?
Drivers experiencing a P0995 code may notice several symptoms, such as:
- Transmission may not shift properly
- Increased fuel consumption
How Serious Is the P0995 Code?
The P0995 code is classified as urgent, indicating that immediate action is necessary. Ignoring this code can lead to significant transmission damage or compromise the safety of the driver and passengers. Therefore, it is essential to address the issue promptly.
How to Diagnose the P0995 Code
To accurately diagnose the P0995 code, a mechanic should follow these steps:
- Use an OBD-II scanner to confirm the presence of the P0995 code and check for any additional codes that may indicate related issues.
- Inspect the transmission fluid level and condition, ensuring it is at the proper level and free of contaminants.
- Test the transmission fluid pressure sensor and its electrical connections for signs of damage or malfunction.
- Examine the wiring for continuity and any potential shorts or breaks.
Common Repairs for the P0995 Code
Common repairs to address the P0995 code may include:
- Replacing the transmission fluid pressure sensor
- Repairing or replacing damaged wiring or connectors
- Refilling or changing the transmission fluid
- Replacing the Transmission Control Module (TCM) if it is found to be faulty
How Much Does It Cost to Fix the P0995 Code?
The cost of repairs related to the P0995 code can vary widely based on the specific issue and vehicle make and model. On average, repairs might cost between $100 to $1,500, depending on whether it’s a simple fluid change or a more complex module replacement.
Can I Fix the P0995 Code Myself?
While some DIY enthusiasts may be able to address minor issues such as checking fluid levels or replacing a sensor, it is recommended to consult with a professional mechanic for a thorough diagnosis and repair, especially given the urgent nature of the P0995 code.
