P0A26Generator Torque Sensor Circuit Intermittent
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0A26 points to short interruptions or jumps in the generator torque sensor signal rather than a constant fault. The control unit counts implausible signal changes or brief out-of-range events and sets the code once a calibrated limit is exceeded. Because the sensor works next to the generator, as in the Honda patent with a sensor in a hollow generator or motor shaft, heat cycles, vibration and inverter noise favour loose contacts and chafed wires. No manufacturer documents P0A26 publicly; CARB requires an approved generator monitor. Permanent faults show as P0A24 or P0A25. Symptoms often appear only on rough roads.
- What you may notice
- Hybrid warning that comes and goes
- Brief drop in charging or system power
- Likely causes
- LikelyLoose or fretted terminal in the sensor connector
- PossibleChafed wiring near the generator housing
- RareShield or ground damage letting inverter noise in
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
