14 Volt Power Module Current Sensor Circuit Low

• What does that mean?
• Symptoms
• Causes
• Solutions

The P0A88 fault code is triggered by the detection of an abnormally low current signal from the 14 Volt Power Module Current Sensor Circuit. This may indicate an issue with the sensor itself or an electrical fault in the circuit. It is critical for the proper functioning of the hybrid or electric vehicle's power system.

What are the symptoms of the P0A88 code?

Symptoms of a P0A88 fault code may include:

• Reduced vehicle performance
• Warning lights on the dashboard, particularly the check engine light
• Difficulty in starting the vehicle
• Possible failure of the hybrid or electric drive system

What causes the P0A88 code?

Common causes for the P0A88 code include:

• A malfunctioning current sensor
• Wiring issues such as shorts or open circuits
• Loose or corroded connectors
• Faulty power module causing improper current flow

How to fix P0A88?

To resolve the P0A88 fault code, it is recommended to:

• Inspect and test the current sensor and associated wiring for damage
• Check and clean all electrical connectors to ensure proper contact
• Replace any faulty components, including the current sensor or wiring, as necessary
• Clear the fault code and conduct road tests to ensure proper functionality
