Code P011B Honda Description

Two Engine Coolant Temperature (ECT) Sensors and one Intake Air Temperature (IAT) Sensor are used by the Powertrain Control Module (PCM). When the engine is stopped and enough time has passed, the temperature of the engine will equalize to the ambient temperature. ECT Sensor 1 and IAT sensor are compared to ECT Sensor 2, and if an inappropriate temperature is read, the PCM detects a malfunction in the corresponding sensor and stores a Diagnostic Trouble Code (DTC).
