The fault code is P1A4A.

The estimated repair time is 1.0 hour. The cost of fixing the fault code is influenced by the repair time.

Most auto repair shops charge between $75 and $150 per hour. Therefore, the fixing cost of the P1A4A fault code will be between $75 and $150.

The P1A4A code relates to the Hybrid Battery Current Sensor Performa. It is based on the closed-loop principle.

A soft-magnetic probe is used as a field detector of the primary current magnetic field. Compared to standard sensors with Hall-probes, the magnetic probe offers several application advantages.

These include low offset currents, small temperature dependence, and no long term drift of offset current. The sensor is also compact in size, and separate electronics are available.

What are the possible causes of the P1A4A automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1A4A fault code. This code is usually caused by a faulty hybrid battery current sensor, an open or shorted hybrid battery current sensor harness, or a poor electrical connection in the hybrid battery current sensor circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I fix the P1A4A automobile fault code?

If you’re experiencing an illuminated Engine Light or Service Engine Soon Warning Light, it could be due to a faulty Hybrid Battery Current Sensor, an open or shorted Hybrid Battery Current Sensor harness, or a poor electrical connection in the Hybrid Battery Current Sensor circuit. To fix this issue, visually inspect the wiring harness and connectors for any damage or corrosion. Check for broken, bent, pushed out, or corroded connector’s pins.

What should I visually inspect to diagnose the P1A4A automobile fault code?

If you’re experiencing the P1A4A fault code, you may notice that your engine light is on. This could be due to a faulty hybrid battery current sensor, an open or shorted harness, or a poor electrical connection in the sensor circuit.
