P0A24Generator Torque Sensor Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0A24 is stored when the voltage from the generator torque sensor stays under its lower diagnostic limit for a calibrated time. Electrically this means the line is pulled toward ground, the sensor supply is missing or the signal wire is broken. The sensor measures torque on the shaft of the engine-driven generator; a Honda patent describes such a sensor inside a hollow generator or motor shaft. No manufacturer documents P0A24 publicly; CARB requires an approved generator monitoring plan. The upper limit is P0A25, implausible but valid readings are P0A23, short dropouts P0A26. Electric generation may be cut back.
- What you may notice
- Hybrid system warning light
- Reduced charging and system power
- Likely causes
- LikelySignal line shorted to ground
- PossibleSensor supply voltage missing
- RareSensor electronics failed with output stuck low
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
