Common Questions
What does P0995 mean and how does it affect my car?
The P0995 code indicates a problem with the transmission fluid temperature sensor, which is crucial for monitoring fluid temperature. If this sensor fails, it can lead to overheating, poor shifting performance, and even transmission failure. It's important to address this issue promptly to maintain your vehicle's performance and reliability.
What are the most common causes of P0995 and how much does it cost to fix?
The most common cause of P0995 is a faulty transmission fluid temperature sensor, with repair costs typically ranging from $150 to $300. Other causes include wiring issues and low transmission fluid levels, which can lead to additional repair costs. Always consult a professional for accurate diagnostics.
Can I drive my car with P0995 or should I stop immediately?
While you may be able to drive your vehicle short distances with the P0995 code, it is not advisable. Continuing to drive can lead to more severe transmission damage and costly repairs. It's best to have the issue diagnosed and repaired as soon as possible.
How can I diagnose P0995 myself using GeekOBD APP?
Using the GeekOBD APP, you can perform an OBD2 scan to retrieve the P0995 code and any related codes. The app provides freeze frame data that shows the vehicle's condition at the time of the fault, helping you pinpoint the problem. Follow the diagnostic steps to test the sensor and wiring.
What vehicles are most commonly affected by P0995?
Common vehicles affected by the P0995 code include the 2011-2016 Ford F-150, 2013-2017 Ford Explorer, and various GM models. Always check for any manufacturer recalls or technical service bulletins related to transmission issues.
How can I prevent P0995 from happening again?
Preventive maintenance is key. Regularly check and change your transmission fluid according to the manufacturer's recommendations, inspect wiring for wear, and keep an eye on transmission performance to catch issues early.
What is P0995?
The P0995 diagnostic trouble code (DTC) indicates a problem related to the transmission fluid temperature sensor's range or performance. This sensor plays a critical role in monitoring the temperature of the transmission fluid, which is essential for optimal transmission operation. When the transmission fluid temperature exceeds or falls below the expected range, the engine control module (ECM) records this anomaly, triggering the P0995 code. Real-world implications of this code include poor transmission performance, such as slipping or harsh shifting, and can lead to overheating, which may cause severe damage to the transmission system over time. Common vehicles affected by this code include the 2011-2016 Ford F-150, 2013-2017 Ford Explorer, and various models from General Motors. If left unresolved, the issue could escalate, leading to more expensive repairs, increased fuel consumption, and reduced vehicle reliability, which emphasizes the importance of addressing the P0995 code promptly.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0995 is present:
- Check engine light illuminates or blinks constantly, indicating a transmission-related issue that needs attention.
- Transmission may hesitate during acceleration, causing a delay in power delivery when you press the gas pedal.
- You may notice a significant drop in fuel economy, with reports indicating a decline of 10-15% due to inefficient transmission operation.
- Unusual noises from the transmission, such as grinding or whining, could occur, signaling potential internal issues.
- Harsh shifting between gears, which can feel like a jolt, may occur, indicating that the transmission is struggling to adapt.
Possible Causes
Most common causes of P0995 (ordered by frequency):
- The most common cause of P0995 is a faulty transmission fluid temperature sensor, which occurs in approximately 60% of cases. This can happen due to wear and tear or electrical issues.
- A second potential cause is damaged wiring or connectors leading to the transmission fluid temperature sensor, which can impede signal transmission to the ECM.
- Another cause could be low transmission fluid levels or contaminated fluid, which can affect the sensor's ability to read temperature accurately. Regular fluid checks can prevent this issue.
- Less common but serious is a malfunctioning ECM, which may incorrectly interpret the sensor's readings. This requires professional diagnosis and potential ECM replacement.
- A rare but possible cause is internal transmission failure, such as a failing pump, leading to overheating and incorrect temperature readings.
