P08ECDrive Motor A Clutch Pawl Position Circuit High
- 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 above its valid range. Typical reasons are an open signal or ground wire, which lets the input float high, or a short to a supply voltage. The module then has no trustworthy feedback on whether the clutch is engaged. No manufacturer documents this code publicly; the closest documented hardware is the disconnect clutch switch on the Corvette E-Ray front drive unit, tied by GM only to P08ED, and patents on pawl or strut clutches with position sensors show the principle. CARB requires out-of-range monitoring. P08EB is the low-side fault, P08EA the general circuit fault, P08ED the plausibility check. Electric drive on that axle is usually locked out.
- What you may notice

- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
