P2752 flags a sensor C circuit that cuts out now and then, briefly enough that neither the circuit code P2749 nor the no-signal code P2751 matures. No manufacturer documents P2752 publicly. The closest published counterpart is Ford's P2748 for sensor B on its ten-speed automatics, an intermittent check that runs continuously beside the circuit and plausibility tests. CARB expects every such transmission input to be monitored for circuit faults. In practice the culprit is mechanical stress on the wiring: a terminal that loosens when hot, insulation worn through on a bracket, or water that wicks into the plug. Watching sensor C while flexing the harness, and reading the freeze frame, are the most useful steps.

Likely causes

Terminal losing contact when hot
Insulation worn through at a bracket or edge
Water ingress into the connector

Symptoms

  • Sporadic warning lamp
  • Occasional rough shift
