P0A60 covers the current in phase V of drive motor A. Toyota uses it with sub codes: a field report filed with NHTSA describes a 2006 Highlander Hybrid whose master warning lit and which would not move; P0A60 sub code 501 had set first, followed by P0A63, P0A78 and P0AEF, all returning at once after clearing, and the inverter assembly was replaced. Another Highlander showed P0A60 and P0A63 together with the generator phase codes P0A72 and P0A75, again an inverter fault; Toyota lists only V and W phases there, matching inverters that measure two phases and calculate the third. Audi stores P0A6000 on the 2021-23 Q5 e quattro for a faulty high-voltage phase lead. P0A61/P0A62 are low and high, P0A5D and P0A63 phases U and W.

Likely causes

Internal fault in the inverter assembly (Toyota Highlander Hybrid)
High-voltage phase V cable or weld joint faulty (Audi Q5 e quattro)
Phase V current sensor failed
Winding fault in phase V of drive motor A

Symptoms

  • Master warning or drive system fault message, MIL
  • Vehicle will not move or start
