P2C4E: Clutch Actuator Position Sensor Circuit Intermittent/Erratic

Standardized SAE J2012 code · P2Cxx codes

What does P2C4E mean?

The clutch actuator position sensor reports a circuit intermittent/erratic condition. Clutch engagement state cannot be measured reliably.

The code tells you which monitor failed, not which part is broken. Test before replacing parts.

Symptoms

  • Check engine or transmission warning light on
  • Harsh, delayed, or missing shifts
  • Possible limp mode (locked in one gear)
  • Slipping or shuddering during gear changes

Common causes

  • High Sensor connector not seated
  • Medium Noisy ground reference
  • Low Connector with intermittent contact under vibration

Likelihood is a general estimate across vehicles; your make and model may differ.

Add your car to see reports of P2C4E on the same make and model first.
