P0A60: Drive Motor A Phase V Current

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.

Symptoms

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

Most 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

What to check, in order

Start with the simplest. You can tick off each step.

1. Read the codes with a hybrid-compatible scanner and write down the freeze frame data
2. Make sure the battery cooling air intake is clean
3. Check the 12 V auxiliary battery, which can also trigger warnings
4. Leave any high-voltage measurements to a specialized repair shop

Good to know

• It can trigger limp mode.
• It affects emissions.

What each character of P0A60 means

• P: Powertrain: engine and transmission
• 0: Generic code: same on every make
• A: Hybrid or air and fuel
• 60: Specific fault in that system

Frequently asked questions

Can I keep driving with code P0A60?

If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.

What causes code P0A60?

The most common causes are: 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.
