This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer detected a problem with the sensor that measures the electric current going to the motor. It's like the sensor is saying the current is too low.
The P1B58 code indicates that the current sensor for the drive motor 'A' is reporting a current value that is lower than expected.
The P1B58 code is triggered when the Powertrain Control Module (PCM) or the Battery Energy Control Module (BECM) detects that the current sensor for the drive motor 'A' is reading a value that is lower than the specified threshold. This could indicate a fault in the sensor, the wiring, or the motor itself.
• Illuminated Check Engine Light
• Reduced vehicle performance
• Possible stalling or hesitation
• Unusual noises from the motor
• Faulty current sensor
• Wiring issues such as shorts or open circuits
• Defective drive motor
• Malfunctioning PCM or BECM
PCM: Powertrain Control Module
BECM: Battery Energy Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors related to the current sensor.
• Test the current sensor for proper operation.
• Check the drive motor for any signs of damage or malfunction.
• Repair or replace faulty wiring or connectors.
• Replace the current sensor if found defective.
• Repair or replace the drive motor if necessary.
• Reprogram or replace the PCM/BECM if needed.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Volt
• Nissan Leaf
• Toyota Prius
• Regular maintenance checks on the electrical system
• Ensure proper battery health
• Avoid exposing the vehicle to extreme conditions
Sensor Issue
• Avoid driving the vehicle until repaired to prevent further damage.
• Consult a professional mechanic for accurate diagnosis and repair.
Check with the vehicle manufacturer for warranty coverage on hybrid or electric components.
This code is commonly associated with hybrid and electric vehicles as they rely on precise current measurements for motor control.
Moderate – It is advisable to address this issue soon to avoid potential driveability problems.
Driving with this code may lead to reduced performance and safety risks. It is recommended to have it diagnosed and repaired promptly.
• Vehicle in 'Ready' mode
• Battery charge level within normal range
The current sensor is typically located near the drive motor or integrated within the power electronics module.
Q: Can I drive with a P1B58 code?
A: It's not recommended to drive with this code as it may cause further damage or reduce vehicle performance.
Q: How do I reset the P1B58 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is resolved, it should not return.
