Engine Coolant Temperature (ECT) Circuit High Input
Was bedeutet das?
Code P0118 indicates the ECT sensor voltage is higher than expected, suggesting the sensor reports excessively low temperature.
Haftungsausschluss: Dieser Diagnosecode ist Teil des OBD2-Standards und gilt für Mitsubishi Pajero Modelle von 1996 bis 2026. Bitte beachten Sie jedoch, dass dies von der genauen Motorkonfiguration abhängt.

Wie man diagnostiziert
Häufige Lösungen
Replace the Engine Coolant Temperature (ECT) Sensor: This is by far the most frequent solution for P0118. If the sensor's internal resistance is out of specification or shows an open circuit, replacing it with a high-quality OEM or equivalent aftermarket part will resolve the issue.
Repair or Replace Damaged Wiring and/or Connector: If the visual inspection or electrical tests reveal corroded, frayed, or broken wires, or a damaged electrical connector at the ECT sensor, the affected section of the harness or the connector itself must be repaired or replaced. Use proper soldering and heat-shrink techniques for durable repairs.
Repair an Open Circuit in the Signal Wire to the PCM: If diagnostic steps confirm an open circuit in the signal wire between the ECT sensor connector and the PCM, the break must be located and properly repaired. This often involves tracing the harness carefully, as damage can be hidden.
