The P0AB1 fault code refers to the Hybrid Battery Pack Air Temperature Sensor ‘B’ Circuit. This sensor is located on the HV battery assembly and measures the intake air temperature.

Its resistance value changes with variations in the intake air temperature.

The battery ECU uses the signals from this sensor to adjust the air flow speed of the battery blower assembly.

The characteristics of the intake air temperature sensor are similar to the battery temperature sensors.

What are the possible causes of the automobile fault code P0AB1?

If you see the engine light or service engine soon warning light on, the fault code P0AB1 could be the culprit. This code is often caused by a faulty HV Battery Assembly, specifically the Intake Air Temperature Sensor. Other possible causes include an open or shorted HV Battery Assembly harness, poor electrical connection in the HV Battery Assembly circuit, or a faulty Battery ECU. To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors to fix the P0AB1 fault code?

If you’re dealing with the P0AB1 fault code and your engine light is on, it’s time to visually inspect the wiring harness and connectors. This fault code is often caused by a faulty HV Battery Assembly or issues with the harness and circuit connections. To fix it, check for any damaged components and examine the wiring harness and connectors for any signs of damage, such as broken, bent, pushed out, or corroded pins. Don’t forget to also consider the other possible causes mentioned above.

What should I look for when checking for damaged components or corroded connector pins to resolve the P0AB1 fault code?

When resolving the P0AB1 fault code, start by checking for damaged components or corroded connector pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any broken, bent, pushed out, or corroded pins. By doing this, you can identify any faults in the HV Battery Assembly or its circuit connections. Don’t forget to also check the HV Battery Assembly harness for any open or shorted circuits.
