P1116 is a OBD-II manufacturer-specific code for a voltage issue with the engine coolant sensor in that the signal being sent to the engine computer is not within the range set by the manufacturer. This usually means the sensor is inoperable and will not be able to accurately relay an engine coolant temperature reading to the driver. Your vehicle will also conduct several self tests of the sensor at start up, and if it fails multiple times, a P1116 will be triggered.
The most common causes for a P1116 are:
enter link description here In addition to a Check Engine Light, a P1116 code will typically result in an inoperable temperature gauge. This may or not mean the actual engine coolant temperature is higher or lower than what would be considered normal.
Your mechanic will first visually inspect the engine coolant temperature sensor and associated wiring, looking for any obvious damages. If everything appears normal, they will then use an OBD-II scanner and a digital voltmeter to test the sensor’s signal range. If it is not within the manufacturer’s parameters, it will be replaced. If the sensor is working as it should, the engine computer may need to be replaced.
Because all P1116 codes are manufacturer specific, it’s critical to have any code read by a professional-grade OBD-II scanner to ensure you’re fixing the problem correctly.
Not being able to accurately read the engine’s coolant temperature, which is likely the result of a P1116, can be dangerous in that you run the risk of unknowingly overheating the engine.
The most common repairs for a P1116 are as follows:
