This summary uses the existing diagnostic information shown in full below.
This code means the car's computer thinks the engine isn't making enough power. Imagine if you were pedaling a bike but not pushing hard enough; the bike wouldn't go very fast.
The code P1B11 indicates that the powertrain control module in a hybrid or electric vehicle has detected a torque value that is lower than expected.
The Hybrid/EV Powertrain Control Module monitors the torque output of the electric motor or engine. If the torque sensing value is below the expected threshold, it triggers the P1B11 code. This could be due to a sensor error, a communication issue, or a problem with the motor or engine itself.
• Reduced power or acceleration
• Check engine light is on
• Unusual noises from the engine or motor
• Faulty torque sensor
• Issues with the powertrain control module
• Electrical problems or wiring issues
Torque: A measure of the rotational force of the engine or motor.
Powertrain Control Module: The computer that controls the engine and transmission functions.
• Check for any additional codes and address them first.
• Inspect the wiring and connections to the torque sensor.
• Test the torque sensor for proper operation.
• Replace or repair the torque sensor if faulty.
• Repair any damaged wiring or connections.
• Reprogram or replace the powertrain control module if necessary.
• OBD-II scanner
• Multimeter
• Torque sensor tester

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance checks
• Ensure proper wiring connections
• Use the correct type of motor oil
Sensor Issue
• Avoid heavy acceleration until repaired.
• Schedule a service appointment promptly.
Check with the vehicle manufacturer for warranty coverage on hybrid/EV components.
This code has been reported in hybrid and electric vehicles since their introduction, often related to sensor or module issues.
Moderate – It should be addressed soon to prevent further issues.
Driving with reduced power can be hazardous, especially in traffic. Ensure repairs are made to maintain vehicle safety.
• Vehicle in 'Ready' mode
• Engine or motor running
The torque sensor is typically located near the powertrain or transmission assembly.
Q: Can I drive with a P1B11 code?
A: It's possible, but not recommended due to reduced power and potential safety risks.
Q: How do I reset the P1B11 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
