Battery Current Sensor Circuit Range/Performance Problem
The battery current sensor has detected a voltage or current that's outside its expected range.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The battery current sensor measures how much power is flowing to and from the battery. If it sees too much or too little current, it sets this code.
What the computer is actually seeing
The computer monitors the voltage (should be around 0-5V) and the current flow (should correlate to the expected load). If it detects values that exceed the threshold (usually above 1.0V with improper current readings), it triggers this code.
What a healthy reading looks like
The battery current should be within a range of -200A to +200A during normal operation, with voltage readings from the sensor expected between 0.5V to 4.5V under normal conditions.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the wiring and connectors going to the battery current sensor for damage or corrosion. If found, repair or replace.
- 22. Check the battery voltage with a multimeter. It should read between 12.4V and 12.7V when fully charged. If not, charge or replace the battery.
- 33. Use a scan tool to monitor the current readings from the battery current sensor while the vehicle is running to see if they are within specs. If out of range, consider the sensor defective.
- 44. If the readings are normal, check the battery control module (BCM) for faults or issues.
Common causes
- Faulty battery current sensor
- Open or short in the wiring harness
- Corroded connectors
- Weak or failing battery
- Battery control module issues
