Symptoms

  • Low or unstable sensor readings
  • Check Engine light on
  • Unstable engine operation
  • Multiple Circuit C Sensor Error Codes
  • Engine transition to emergency mode

Causes

  • Short circuit in the sensor, loading circuit C
  • Shorting the power wire to ground
  • Moisture getting into the sensor or ECU connector
  • Malfunction of the internal power supply stabilizer of the ECU
  • Damaged power conductor insulation

How to Fix

  1. Measure the supply voltage at terminal C with the ignition on.
  2. Identify the sensors powered by circuit C using the electrical diagram
  3. Turn off the sensors one by one and monitor the voltage restoration
  4. Check the internal resistance of the found β€œculprit” sensor
  5. Check the continuity and insulation of circuit C wiring
  6. If the voltage is normal without sensors, diagnose the ECU
