OBD-II Chassis Error Code C0800: How to Fix It

Q: Can I drive with OBD-II error code C0800?

You can drive with C0800, but the power steering will not function, making steering much harder especially at low speeds and when parking. Drive only if necessary and have it repaired immediately for safety.

Q: Will a dead battery cause C0800 error code?

Yes, a failing or dead battery is the most common cause of C0800. Even if the car starts, a weak battery may not provide enough voltage for the EPS system to operate safely.

Q: How much does it cost to fix C0800 error code?

If it's just a battery issue, expect $100-200 for a new battery. If the alternator needs replacement, costs range from $300-600. EPS system component replacement can cost $500-1500 depending on the vehicle.

Q: Will C0800 code clear itself after fixing the battery?

The code may clear itself after several drive cycles with proper voltage, but it's recommended to manually clear it with an OBD-II scanner to immediately restore EPS function.

Q: Why does my steering wheel feel heavy with C0800?

When C0800 triggers, the Electric Power Steering system shuts down as a safety measure. This leaves you with manual steering only, which requires significantly more effort, especially at low speeds.

Abstract

OBD-II error code C0800 indicates that your vehicle's Electric Power Steering (EPS) system has been disabled due to low battery voltage. This safety feature prevents potential steering damage when the electrical system cannot provide adequate power to operate the power steering assist.
