C0074 code meaning
Requested Driving Torque
What C0074 means
Covers the requested-driving-torque signal that the ABS/ESC module sends to the powertrain controller during traction and stability control, the counterpart to the delivered-torque signal C0073. When a driven wheel spins the stability controller computes a torque-reduction request and transmits it; this code is set when that request path is faulty, the value is out of range, or the request and the powertrain's response are inconsistent. Traction-control patents describe how the controller overrides the driver's torque demand transiently to bring slip to target by cutting spark, fuel or throttle. A fault limits traction and stability control and sets the ABS/ESC warning lamp while base braking remains; it usually appears together with powertrain or communication codes. The entry follows the SAE J2012 generic definition.
C0074 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C0074
- Traction and stability control limited
- ABS/ESC warning lamp on
- Appears with powertrain DTCs
Common causes of C0074
- Most likelyFault on the torque request path
- PossibleStability or powertrain module fault
- Less likelyMismatched controller calibration
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C0074 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C0074
What does C0074 mean?
C0074 means "Requested Driving Torque". Covers the requested-driving-torque signal that the ABS/ESC module sends to the powertrain controller during traction and stability control, the counterpart to the delivered-torque signal C0073. It is a generic code, so it means the same on every make.
Is it safe to drive with C0074?
Drive gently and only to a workshop. With C0074 the car can go into limp mode (reduced power) to protect itself.
Will C0074 fail an emissions test?
C0074 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C0074 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will C0074 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
