P0116 MERCEDES-BENZ code

Error code OB0 II P0116 is defined as “Engine Coolant Temperature Circuit Malfunction” and is set when the ECM (Engine Control Module) detects a voltage in the engine coolant temperature sensor circuit that is out of range. Worn, damaged, shorted or corroded wires and connectors.

How do I fix P0116 code?


Zitat von Youtube: In most cars the primary ect sensor is installed near the thermostat in the cylinder. Head remove the ecd sensor from the engine. Use a multimeter to proceed a test on the ect.

What can cause a P0116 code?

Diagnostic trouble code (DTC) P0116 stands for “Engine Coolant Temperature Sensor 1 Circuit Range/Performance.” This DTC is triggered by the PCM after it detects that the voltage signals relayed by the engine coolant temperature (ECT) sensor fall outside the normal manufacturer-specified range.

What does trouble code P0116 mean?

The Engine Coolant Temperature Sensor converts the coolant temperature into a voltage that is high when the engine is cold and low as the engine warms up. Code P0116 is set when the Powertrain Control module sees irrational out of specification voltage signals from the coolant temperature circuit.

Where is coolant temperature sensor?

In most cars, the primary ECT sensor (ECT sensor 1) is installed near the thermostat in the cylinder head or block or on the thermostat housing. A second coolant temperature sensor could be installed in another part of the engine, or in the radiator.
