Resistance Inspection: Notes

  1. Disconnect the CHT sensor connector.
  2. Measure the resistance between the CHT sensor terminals.
    • If it is not within the specification, replace the CHT sensor.
    • If the monitor item status/specification (reference) is not within the specification, even though the resistance is within the specification, perform the "Circuit Open/Short Inspection".

Measure the cylinder head temperature sensor resistance (approx.).
