P0116 – Engine Coolant Temperature Circuit Range/Performance
Encountering the P0116 code in your Geely? Here is a complete guide to its causes, symptoms, and solutions.
WHAT DOES CODE P0116 MEAN
The P0116 trouble code is an OBD2 code that indicates a problem with the engine coolant temperature circuit. This code is often associated with issues related to the engine coolant temperature sensor, which is responsible for monitoring the engine’s temperature and sending this information to the engine control module (ECM). When the ECM detects a problem with the sensor or the circuit, it will trigger the P0116 error. Diagnosing the P0116 code requires a thorough understanding of the engine’s cooling system and the sensor’s operation.

DIAGNOSTIC STEPS
To diagnose the P0116 code, an auto-electrician should start by inspecting the engine’s cooling system, including the coolant temperature sensor, wiring, and connections. The technician should verify the sensor’s operation and check for any signs of corrosion or damage. The ECM’s software and calibration should also be checked to ensure they are up-to-date and functioning correctly. The technician should consult the workshop manual for the specific Geely model to determine the correct diagnostic procedures and specifications.
HOW TO FIX
Fixing the P0116 code typically involves replacing the faulty coolant temperature sensor or repairing the wiring and corrosion issues. The technician may also need to update the ECM’s software or recalibrate the system. In some cases, the thermostat or thermostat housing may need to be replaced. The technician should follow the recommended repair procedures and consult the workshop manual for the specific Geely model.
IS IT SAFE TO DRIVE WITH THIS CODE
Driving with the P0116 code can pose technical risks to the vehicle, including engine damage, overheating, and decreased fuel efficiency. It is recommended to address the issue as soon as possible to avoid any further damage to the engine or other components.
ESTIMATED REPAIR COST
The estimated repair cost for the P0116 code can range from $200 to $1,000, depending on the specific repair needed and the labor costs.
PREVENTIVE MAINTENANCE TIPS
To prevent the P0116 code from occurring, it is essential to maintain the engine’s cooling system properly. This includes checking the coolant levels regularly, inspecting the wiring and connections, and ensuring the thermostat is functioning correctly. Regular maintenance can help prevent issues with the coolant temperature sensor and other components.
When diagnosing the P0116 code, it is crucial to inspect the wiring and connections carefully, as corrosion or damage can be difficult to detect. Additionally, ensuring the ECM’s software is up-to-date and calibrated correctly can help prevent issues with the coolant temperature sensor. Regular maintenance and inspections can help prevent the P0116 code from occurring and reduce the risk of engine damage.
