Common Symptoms of Faulty Coolant Temperature Sensors

• Check engine light illuminated (P0115-P0119 codes)
• Poor fuel economy
• Rough idle or stalling when cold
• Engine overheating or running too cool
• Cooling fan running constantly or not at all
• Black smoke from exhaust during warm-up
• Difficulty starting when engine is cold
• Incorrect temperature gauge readings

What Does a Coolant Temperature Sensor Do?

The coolant temperature sensor (CTS) monitors the temperature of the engine coolant and sends this critical information to the engine control unit (ECU). The ECU uses this data to adjust fuel delivery, ignition timing, and cooling fan operation. During cold starts, the sensor signals the ECU to enrich the fuel mixture for smooth operation. As the engine warms up, it helps optimize performance and fuel efficiency.

Why Choose OEM-Quality Coolant Temperature Sensors?

OEM-quality coolant temperature sensors are engineered to meet or exceed original equipment specifications, ensuring accurate temperature readings across the full operating range. Inferior aftermarket sensors can provide incorrect readings, leading to poor performance, increased emissions, and potential engine damage. Quality sensors ensure reliable operation and long service life.
