DTC P0A0F-204: Engine Failed to Start; DTC P0A0F-205: Engine Failed to Start; DTC P0A0F-206: Engine Failed to Start; DTC P0A0F-524: Engine Failed to Start; DTC P0A0F-525: Engine Failed to Start [11/2016 - ]: Description
WARNING: This page is about a different car, the 2019 Toyota Highlander, 2018 Toyota Highlander, and 2017 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
If an engine malfunction occurs, an engine malfunction signal is sent from the ECM to the hybrid vehicle control ECU assembly. When the hybrid vehicle control ECU assembly receives this signal, it stores a DTC and performs fail-safe control.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
|---|---|---|---|---|---|
| P0A0F-204 | Engine Failed to Start | Signal indicating abnormality is received from the ECM (abnormal engine output) Actual engine torque is very low compared to the target torque. (1 trip detection logic) |
SFI system | Does not come on | Master Warning Light: Comes on |
| P0A0F-205 | Engine Failed to Start | Signal indicating abnormality is received from the ECM (engine unable to start) (1 trip detection logic) |
SFI system | Does not come on | Master Warning Light: Comes on |
| P0A0F-206 | Engine Failed to Start | Signal indicating abnormality is received from the ECM (engine component malfunctioning, drop in torque) (1 trip detection logic) |

HINT:
- The hybrid vehicle control ECU assembly stores DTC P0A0F-204, 205, 206, 524 or 525 when it receives a signal from the ECM indicating abnormal engine power, engine starting malfunction, engine performance deterioration (running out of fuel), crank angle sensor circuit DTCs or cam position sensor circuit DTCs.
- If the engine cannot start, the vehicle is driven using EV drive mode. However, if the vehicle is continuously driven using only EV drive mode, the HV battery will be discharged and the vehicle will not be able to be driven.
- If any of these DTCs are output, it is required to repair the SFI system in accordance with the DTC or to add a sufficient amount of fuel.
