P08EADrive Motor A Clutch Pawl Position 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
- Concerns the sensor or switch that reports where the pawl of the drive motor A disconnect clutch sits, i.e. whether the form-locking clutch is engaged or released. The code sets when the control module finds an electrical fault in that signal circuit, such as an open line or a signal outside its valid states. No manufacturer documents this code publicly. GM fits a drive motor disconnect clutch switch to the front drive unit of the Corvette E-Ray and blames it for P08ED; pawl clutches with dedicated position sensors are described in supplier patents such as one from Means Industries. CARB requires input circuit checks. P08EB and P08EC are the low and high variants, P08ED the plausibility fault. Electric drive on that axle is usually inhibited.
