It's advised to stop driving your vehicle immediately if you see the P0968 code. Continuing to drive can lead to further damage and more expensive repairs.
How can I diagnose P0968 myself using GeekOBD APP?
Using the GeekOBD APP, you can scan your vehicle's OBD2 system to retrieve codes and freeze frame data. This will help you understand the context of the P0968 code and guide your next steps.
What vehicles are most commonly affected by P0968?
The P0968 code is most commonly seen in vehicles such as the 2015-2018 Honda Accord and Toyota Camry. Always check for any recalls or technical service bulletins (TSBs) related to this code.
How can I prevent P0968 from happening again?
Regular maintenance, including checking and changing transmission fluid, inspecting wiring and connectors, and addressing any leaks promptly, can help prevent the recurrence of the P0968 code.
What is P0968?
The diagnostic trouble code (DTC) P0968 refers to 'Pressure Control Solenoid A Range/Performance Problem.' This code indicates that the Engine Control Module (ECM) has detected an issue with the pressure control solenoid A, which is crucial for regulating hydraulic pressure within the transmission. A malfunction in this system can lead to erratic shifting, slipping gears, or reduced fuel efficiency. The pressure control solenoid plays a key role in managing the hydraulic pressure needed for the transmission to operate smoothly. When the ECM receives readings that are outside the expected range, it triggers the P0968 code, signaling a need for immediate attention. If left unaddressed, the symptoms can worsen, leading to more severe transmission issues or complete failure, which can result in costly repairs down the line. Commonly found in vehicles like the 2015-2018 Honda Accord and Toyota Camry, this code often appears alongside other transmission-related trouble codes, making it essential for car owners to understand its implications and seek timely diagnostics and repairs.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0968 is present:
- Check engine light stays on constantly, indicating a persistent issue that needs addressing.
- Engine hesitates during acceleration, causing a noticeable delay that can affect safe driving.
- Fuel economy decreased by 10-15%, leading to increased costs at the pump and reduced overall efficiency.
- Transmission may slip or experience harsh shifting, making it difficult to drive smoothly.
- Unusual noises from the transmission, such as whining or clunking, indicating potential mechanical failure.
Possible Causes
Most common causes of P0968 (ordered by frequency):
- The most common cause is a faulty pressure control solenoid, with an approximate likelihood of 60%. This can be due to wear and tear or electrical issues.
- A second common cause involves low transmission fluid levels, which can be attributed to leaks or neglect in maintenance. This may lead to transmission overheating.
- The third cause could be electrical issues such as damaged wiring or connectors, which can prevent the solenoid from receiving the correct signals.
- A less common but serious cause is a malfunctioning transmission control module (TCM), which can disrupt the entire operation of the transmission system.
- A rare cause might be internal transmission damage, which could occur due to severe neglect or overheating, necessitating extensive repairs or replacement.
