P08EBDrive Motor A Clutch Pawl Position Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Set when the pawl position signal of the drive motor A disconnect clutch stays below its valid range, which points to a short to ground in the signal wire, a missing sensor supply or a sensor that has failed low. The module then cannot tell whether the pawl has engaged. No manufacturer documents this code publicly; the matching hardware is the disconnect clutch switch on the front drive unit of the Corvette E-Ray, which GM links only to P08ED, and supplier patents describe such position sensing on pawl or strut clutches. CARB requires out-of-range checks on these inputs. P08EC is the high-side fault, P08EA the general circuit fault. The system typically keeps the motor uncoupled and lights a warning.
