Common Questions
What does C1468 mean and how does it affect my car?
C1468 indicates a problem with your vehicle's Electric Power Steering system, affecting your ability to steer safely. If the power steering assist is lost, it can make driving difficult and unsafe, especially at low speeds.
What are the most common causes of C1468 and how much does it cost to fix?
Common causes include wiring issues, a faulty EPS control module, or a malfunctioning steering angle sensor. Repair costs can range from $150 to $1,200 depending on the specific issue and parts needed.
Can I drive my car with C1468 or should I stop immediately?
While you may be able to drive short distances, it's not advisable to continue driving as it can lead to a complete loss of power steering, making the vehicle hard to control. It's best to seek professional help immediately.
How can I diagnose C1468 myself using GeekOBD APP?
Use the GeekOBD APP to scan for trouble codes and view live data from the EPS system. Look for any anomalies in the steering angle readings, and check for any stored DTCs that might give more insight into the issue.
What vehicles are most commonly affected by C1468?
This code is frequently seen in 2015-2020 Toyota models, including the Camry and Corolla. Be sure to check for any recalls or technical service bulletins related to the EPS system.
How can I prevent C1468 from happening again?
Regular maintenance, including checking wiring and connections for wear, keeping the EPS fluid at proper levels, and having the steering angle sensor calibrated periodically can help prevent reoccurrences of this code.
What is C1468?
DTC C1468 is a diagnostic trouble code that indicates an issue with the vehicle's Electric Power Steering (EPS) system, particularly within certain Toyota models produced between 2015 and 2020. This code usually signifies a malfunction in the EPS control module or its associated components, which can lead to steering difficulties and may compromise vehicle safety. When the C1468 code is triggered, it generally means that the EPS system has detected an internal fault, often due to wiring issues, sensor malfunctions, or the EPS control module itself failing to communicate properly. This can manifest in a variety of ways, including a noticeable increase in steering effort, erratic steering response, or even a complete loss of power steering assist. If left unchecked, this could lead to potential safety hazards on the road, making it crucial for drivers to address this code promptly. Ignoring C1468 may result in more severe steering issues or even contribute to accidents due to compromised vehicle control. Therefore, understanding this code and its implications is essential for maintaining vehicle safety and performance.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C1468 is present:
- The check engine light or power steering warning light may illuminate on the dashboard, indicating a serious issue with the steering system.
- Drivers may experience increased steering effort, particularly at low speeds, making it difficult to maneuver the vehicle smoothly.
- Intermittent or erratic steering response can occur, leading to a feeling of instability while driving.
- A decrease in vehicle handling and responsiveness may be noticeable during cornering or when making sharp turns.
- In severe cases, the power steering assist may completely fail, resulting in a heavy steering feel that can be challenging to manage.
Possible Causes
Most common causes of C1468 (ordered by frequency):
- Wiring issues or loose connections in the EPS system are the most common cause of the C1468 code, with a likelihood of about 40%. Corrosion or damage to the wiring can disrupt the electrical signals necessary for proper operation.
- A faulty EPS control module can lead to this code being triggered. This component is responsible for interpreting data from the steering angle sensor and adjusting the steering assist accordingly. If it fails, the entire steering system may be compromised.
- A malfunctioning steering angle sensor can also cause the C1468 code. This sensor provides critical feedback on the steering wheel's position, and any inaccuracies can lead to erratic steering behavior. Regular calibration checks can help prevent this issue.
- Less commonly, problems with the power steering pump or fluid can also trigger this code. Low fluid levels or contamination can impact the performance of the EPS system.
- In rare cases, software issues within the EPS control module may lead to erroneous codes being generated without any actual hardware failure.

Diagnostic Steps
Professional C1468 Diagnosis Process
Follow these systematic steps to accurately diagnose C1468. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Conduct an initial visual inspection for damaged wiring, loose connections, or corrosion around the EPS components, which should take about 5-10 minutes
Step 2: Use an OBD2 scanner or the GeekOBD APP to retrieve all existing trouble codes and freeze frame data to understand the context of the fault, which should take around 10-15 minutes
Step 3: Perform component testing on the EPS control module and associated sensors using a multimeter or diagnostic tools to verify their functionality, which may take 20-30 minutes
Step 4: Run a system function test to ensure all components are operating correctly after repairs and clear any stored codes, requiring about 10-15 minutes
Step 5: Conduct a road test under various driving conditions to confirm that the steering system is functioning properly and that the C1468 code does not reappear, which may take 15-20 minutes
Important Notes
- Always verify the repair with GeekOBD APP after completing diagnostic steps
- Clear codes and test drive to ensure the problem is resolved
- Address underlying causes to prevent code recurrence
