C0244: Engine Torque Signal

What it means

This code has no generic meaning assigned by SAE J2012 or ISO 15031-6. Any description for it is manufacturer-specific.

How it works

C0244 has no generic OBD-II meaning, so the exact engine-torque signal and receiving module depend on the vehicle. If the title matches the vehicle-specific definition, a module is monitoring torque information sent by the engine controller and sets the code when that signal is missing, implausible, or otherwise outside its defined conditions; verify which condition applies before diagnosing it.

Common causes

Most likely first.

1. Manufacturer-specific diagnostic definition
2. Vehicle-specific scan-tool decoding

Symptoms

• Symptoms depend on the vehicle-specific meaning

How to diagnose it

1. Use a scan tool with access to the relevant modules and confirm the vehicle-specific definition, reporting module, and any related codes.
2. Review freeze-frame or event data and compare requested and reported engine torque values if the scan tool provides them.
3. Inspect the relevant module connectors, grounds, and network or signal wiring identified by the vehicle's wiring diagram.
4. Check whether the engine controller has related faults that could make its torque information unavailable or implausible.
5. Test the named signal or communication circuit and confirm module data against the manufacturer's diagnostic procedure.

Common fixes

• Repair loose, corroded, or damaged connectors on the identified signal path.
• Repair wiring or ground faults found between the engine controller and receiving module.
• Resolve related engine-controller faults that disrupt the torque information.
• Replace a module only if vehicle-specific testing confirms that it is not sending or receiving the signal correctly.

Can I keep driving?

Driving effects depend on the vehicle-specific definition; torque-based traction or stability functions may be limited. If the vehicle has reduced power, unstable behavior, or a warning affecting control systems, avoid demanding driving and arrange diagnosis promptly.
