This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the part of the car that checks how hot or cold the engine is. It's like a thermometer for the engine, and it's not working right.
The Engine Coolant Temperature (ECT) Sensor 2 is not providing readings within the expected range, which could affect engine performance.
The P2183 code indicates that the Engine Control Module (ECM) has detected a discrepancy in the readings from the Engine Coolant Temperature Sensor 2. This sensor is responsible for monitoring the temperature of the engine's coolant, which helps the ECM adjust fuel injection and ignition timing for optimal engine performance.
• Check Engine Light is on
• Poor fuel economy
• Engine overheating or running too cool
• Faulty Engine Coolant Temperature Sensor 2
• Wiring issues or poor connection in the sensor circuit
• Faulty Engine Control Module (ECM)
ECM: Engine Control Module, the computer that controls engine functions.
ECT Sensor: Engine Coolant Temperature Sensor, a device that measures the temperature of the engine's coolant.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to the ECT Sensor 2.
• Test the ECT Sensor 2 for proper operation using a multimeter.
• Replace the Engine Coolant Temperature Sensor 2 if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools (screwdrivers, wrenches)
$100 - $300
Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly check and maintain coolant levels.
• Inspect wiring and connectors for damage.
• Ensure proper engine maintenance and servicing.
Sensor Issue
• Avoid driving the vehicle until the issue is resolved to prevent engine damage.
• Consult a professional mechanic for accurate diagnosis and repair.
Check with the vehicle manufacturer for potential warranty coverage on engine sensors.
This code has been commonly reported in vehicles with high mileage or those that have experienced coolant leaks.
Moderate – It should be addressed soon to prevent potential engine damage.
Ignoring this code may lead to engine overheating, which can cause significant damage and safety hazards.
• Engine at operating temperature
• Vehicle stationary
The Engine Coolant Temperature Sensor 2 is typically located near the thermostat housing or on the engine block.
Q: Can I drive with a P2183 code?
A: It's not recommended to drive with this code active, as it can lead to engine overheating and damage.
Q: How do I clear a P2183 code?
A: After repairs, the code can be cleared using an OBD-II scanner, but it will return if the issue is not resolved.

Fitment Required · Vehicle-fitment part
Relevant when coolant-temperature and warm-up faults indicate a thermostat-related issue.
Coolant-temperature and warm-up faults often lead to thermostat testing and replacement.
Thermostats are vehicle-specific and should be matched by engine and housing style.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
