Check the 'Possible Causes' listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
The cost to diagnose the P0AFA code is 1.0 hour of labor. The diagnosis time and labor rates at auto repair shops vary depending on the location, make and model of the vehicle, and even the engine type. Most auto repair shops charge between $75 and $150 per hour.
The Battery Smart Unit monitors the voltage of the battery blocks to detect an open malfunction in the internal battery voltage sensor circuits of the Battery Smart Unit and the wire harness between each battery block and Battery Smart Unit. If a voltage at one of the battery blocks is below a standard level or of all the battery blocks is within a specified range, the Battery Smart Unit judges that there is an open in the internal sensor circuit(s) or wire harness. The Hybrid Vehicle (HV) Control ECU then illuminates the MIL and sets a Diagnostic Trouble Code (DTC).
