This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble getting a steady reading from the sensor that checks how much power the battery charger is sending out. It's like trying to watch a TV show when the signal keeps cutting in and out.
The code P0D4B indicates an issue with the sensor that monitors the output current of the battery charger, specifically that the readings are inconsistent or erratic.
The P0D4B code is triggered when the Powertrain Control Module (PCM) detects an intermittent or erratic signal from the 14-volt output current sensor of the battery charger. This sensor is responsible for monitoring the current being output from the battery charger to ensure it is within the expected range. An erratic signal can indicate a problem with the sensor itself, the wiring, or the battery charger.
• Check Engine Light illuminated

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly inspect battery connections and wiring.
• Ensure battery charger is functioning correctly.
• Perform routine maintenance checks.
Sensor Issue
• Get the vehicle inspected by a professional if the Check Engine Light is on.
• Avoid using high-power electrical accessories until the issue is resolved.
Repairs may be covered under the vehicle's powertrain warranty. Check with the manufacturer.
This code has been associated with hybrid and electric vehicles due to the complexity of their charging systems.
Moderate – While the vehicle may still operate, the charging system's inconsistency can lead to battery issues.
Driving with a malfunctioning charging system can lead to vehicle breakdowns. It is advisable to address this issue promptly.
• Vehicle parked and engine off
• Battery charger connected and active
The current sensor is typically located near the battery charger or integrated within the charging system.
Q: Can I drive with a P0D4B code?
A: While the vehicle may still operate, it's best to get the issue fixed to avoid potential battery problems.
Q: What happens if I ignore this code?
A: Ignoring the code could lead to battery charging issues and eventually cause the battery to fail.
