What vehicles are most commonly affected by C070C?
DTC C070C is often seen in 2015-2019 Ford F-150 models, but it can also affect other vehicles equipped with electronic power steering systems. Regular checks are recommended to avoid issues.
How can I prevent C070C from happening again?
Regular maintenance of your power steering system, including inspections of the PSCM and wiring, can help. Keeping your battery in good condition and updating software as needed is also beneficial.
What is C070C?
DTC C070C is a diagnostic trouble code that indicates an issue with the vehicle's power steering control module (PSCM). This code specifically points to a problem in the communication between the PSCM and other control modules within the vehicle. When the PSCM detects a fault, it triggers the code, and you may notice warnings such as the power steering assist being disabled. This can result in increased steering effort, making your vehicle harder to maneuver, especially at lower speeds. In real-world implications, this code is often encountered in 2015-2019 Ford F-150 models but can also affect other vehicles with electronic power steering. If left unresolved, you may experience a complete loss of power steering, which can lead to dangerous driving conditions. Therefore, understanding this code and its ramifications is crucial for maintaining safe driving conditions and ensuring the longevity of your vehicle's steering system.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C070C is present:
- The check engine light is illuminated, indicating a fault in the power steering system.
- Power steering assist may be partially or completely lost, making it difficult to steer, especially at slow speeds.
- Unusual noise from the steering system, such as whining or grinding, when turning the wheel.
- Steering feels stiff or unresponsive, leading to an uncomfortable driving experience.
- Intermittent loss of steering functionality, where the assist may work sporadically.
Possible Causes
Most common causes of C070C (ordered by frequency):
- Faulty power steering control module (PSCM) - This is the most common cause, accounting for about 50% of cases. A defective PSCM can fail to communicate properly with other modules.
- Wiring issues - Damaged or corroded wiring that connects the PSCM to the vehicle's control units can lead to communication failures, contributing to approximately 30% of cases.
- Sensor malfunctions - Problems with steering angle sensors can mislead the PSCM, causing incorrect responses. Regular calibration and maintenance can help prevent this.
- Battery or alternator issues - Low voltage or inconsistent power supply can disrupt the operation of the PSCM, leading to a fault code. Keep your battery and alternator in good condition.
- Software glitches - Occasionally, software issues in the vehicle's electronic systems can trigger this code. Updates may resolve these problems.
