Battery Charger A Input Voltage Sensor A Circuit Range/Performance
What it means
The battery charger A input sensor A circuit is reading outside the range the module expects or not matching what it should. This input lets the charger monitor the power coming in from the charging source, which it uses to control charging.
Can I keep driving? Usually yes, as this mostly affects charging; get it read if charging fails. Do not open high-voltage (orange) cables or covers yourself; leave that to a trained technician.
What this part does
This sensor measures the voltage that the on-board charger receives from the charging cable on a plug-in hybrid or electric vehicle. The charger control module uses it to check the supply is within range and to decide whether charging can begin. It is part of a high-voltage circuit, so work on it is for trained people. A fault may prevent or interrupt charging.
Common symptoms
What you'll notice
- Battery not charging or charging slowly
- Illumination of the warning light
Common causes
Most likely first
- Malfunctioning battery charger or power supply
- Faulty input current sensor
- Loose or corroded electrical connections
- Short circuit in the input current sensor circuit
- Defective wiring in the battery charger A circuit
How to diagnose & fix
Work through it in order
- Check the battery charger's connections and ensure they are secure
- Verify that the battery charger is receiving power and functioning properly
- Inspect the input voltage sensor circuit for any loose wires or damaged components
- Test the input voltage sensor using a multimeter to ensure it is reading accurately
- If necessary, replace the input voltage sensor circuit with a new one
