P1A4D Code - Hybrid Battery Current Sensor Performance
Quick Answer
The closed loop principle makes use of a zero-field detector signal which is processed to drive a current through a compensation coil in such a way, that it balances out the magnetic field of the applied current at any time. Common causes include Faulty Hybrid Battery Current Sensor, Hybrid Battery Current Sensor harness is open or shorted, Hybrid Battery Current Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1A4D Description
In current sensors based on the closed loop principle the primary current conductor is lead through a magnetic core. The magnetic field of the primary current is concentrated in the magnetic core is detected by a soft-magnetic field probe in an air gap of the core. By means of a current through an additional winding on the core, the magnetic flux of the primary current is compensated. The magnetic flux in the core is held at zero value. The compensation current is proportional, and is an image of the primary current.
The current sensors are based on the closed-loop principle. A soft-magnetic probe is used as field detector of the primary current magnetic field. Compared to standard sensors with Hall-probes, the magnetic probe offers the following application advantages:
- Low offset currents
- Small temperature dependence
- No long term drift of offset current
- Small offset current forces
- Compact size
- Separate electronics available
What are the Possible Causes of the DTC P1A4D?
- Faulty Hybrid Battery Current Sensor
- Hybrid Battery Current Sensor harness is open or shorted
- Hybrid Battery Current Sensor circuit poor electrical connection
