The most common cause of P0795 is a faulty transmission range sensor, which typically costs between $150 and $300 to replace. Other causes include damaged wiring and low transmission fluid, which can also affect repair costs.
Can I drive my car with P0795 or should I stop immediately?
Driving with a P0795 code is not recommended as it may lead to further transmission damage. It’s best to stop driving and diagnose the issue promptly to avoid more extensive repairs.
How can I diagnose P0795 myself using GeekOBD APP?
To diagnose P0795 using the GeekOBD APP, first connect your OBD2 scanner, retrieve the code, and review freeze frame data. Check the transmission range sensor's voltage using the app's data monitoring feature to assess its functionality.
What vehicles are most commonly affected by P0795?
P0795 is commonly found in vehicles like 2000-2015 Honda Accord, 2007-2013 Toyota Camry, and other models equipped with automatic transmissions. Always check for any recalls or technical service bulletins related to your specific model.
How can I prevent P0795 from happening again?
Preventing P0795 involves regular maintenance, including checking and changing transmission fluid as per your vehicle's service schedule, and conducting periodic inspections of the transmission range sensor and wiring.
What is P0795?
The Diagnostic Trouble Code (DTC) P0795 indicates a malfunction in the transmission range sensor circuit. This sensor is crucial for the proper functioning of your vehicle's transmission system. It monitors the position of the gear selector and sends signals to the Engine Control Module (ECM) to ensure that the vehicle operates smoothly in the correct gear. When this code is triggered, it often means that the sensor is either malfunctioning or has lost communication with the ECM. Real-world implications include difficulty shifting gears, unexpected vehicle behavior, and potential transmission damage if not addressed promptly. Ignoring this code can lead to increased wear on your transmission components, decreased fuel efficiency, and ultimately, a costly repair bill. If you drive a vehicle like a 2010 Honda Accord or a 2015 Toyota Camry, being aware of this code and its symptoms can help you take timely action to prevent further issues.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0795 is present:
- Check engine light stays on constantly, indicating a persistent issue with the transmission range sensor.
- Engine hesitates during acceleration, which can feel like a loss of power or stalling when shifting gears.
- Fuel economy decreased by 10-15%, as the vehicle may be operating inefficiently due to improper gear selection.
- Unusual shifting behavior, such as hard or erratic shifts, which can be alarming and may compromise safety.
- Transmission slipping or failing to engage, leading to a significant risk of being unable to drive the vehicle.
Possible Causes
Most common causes of P0795 (ordered by frequency):
- The most common cause is a faulty transmission range sensor, which is responsible for relaying gear position information (60% likelihood).
- A second common cause could be damaged wiring or connectors in the sensor circuit that can disrupt communication (20% likelihood).
- Thirdly, low transmission fluid levels or dirty fluid can affect sensor operation and should be checked regularly for prevention.
- Less common but serious causes include a failing ECM, which can lead to multiple fault codes and complicated repairs.
- A rare but possible cause might be a faulty transmission control module, which could need replacement if diagnosed.
