P08E7Drive Motor A Clutch Enable Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Covers the enable line with which a drive motor control module activates the actuator of a clutch that couples or uncouples electric drive motor A from the wheels. The code sets when the module sees an electrical fault on that line, typically an open circuit or an implausible state. No manufacturer documents this code publicly. The closest known hardware is the front electric drive unit of the 2024 Corvette E-Ray, which has a disconnect clutch actuator, a clutch pawl and a position switch; GM lists separate faults there, such as P08ED and a lost-communication code for the actuator. CARB requires circuit checks on such output components. P08E8 and P08E9 are the low and high variants. The driver usually loses electric assist on that axle.
- What you may notice
