Generator Torque Sensor Circuit Low
The P0A24 code indicates that the hybrid generator torque sensor circuit is reporting a voltage lower than the expected range. This sensor monitors the torque applied to the generator, which is critical for proper hybrid system operation. A low signal can cause the hybrid control module to limit generator output, leading to reduced charging and potential drivability issues.
01. Most Common Causes
- Faulty generator torque sensor
- Open or shorted wiring in the sensor circuit
- Poor electrical connection at the sensor or hybrid control module
- Failed hybrid control module
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced fuel economy
- Loss of hybrid assist or reduced power
- Battery not charging properly
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve all codes and freeze frame data.
Step 2: Inspect the generator torque sensor wiring and connector for damage, corrosion, or loose pins.
Step 3: Measure the sensor reference voltage (typically 5V) and signal voltage at the sensor connector.
Step 4: Compare signal voltage to manufacturer specifications; if low, replace the sensor.
Step 5: If sensor is okay, check for continuity and shorts in the circuit between sensor and hybrid control module.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the hybrid system may fail, leaving you stranded. The vehicle may operate in a reduced power mode.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, including parts and labor, depending on the cause and vehicle model.
