Blue Print ADJ137226 Coolant Temperature Sensor

Description

The Coolant Temperature Sensor from Blue Print is a crucial component that monitors the engine's coolant temperature, providing vital information for optimal engine performance and preventing overheating.

Key Features & Benefits

This little guy basically measures the temperature of your engine coolant. It’s a resistor that changes its electrical resistance depending on how hot or cold the coolant is. That resistance reading is sent to your car’s computer – the Engine Control Unit, or ECU – and that’s how the computer knows what's going on with your engine's temperature. It’s a critical part of your cooling system. The ECU uses the information from this sensor to adjust a bunch of things. Things like how long the engine runs before starting, the fuel mixture, and when the cooling fans kick on. It's like the sensor is the computer's thermometer – it needs an accurate reading to make good decisions. It also controls things like your temperature gauge on the dashboard, so you know how your engine is doing.

Symptoms, Risks & Replacements

If this sensor goes bad, it can cause all sorts of issues. It can make your engine run too rich or too lean, which hurts fuel economy and can damage the catalytic converter. You might get poor performance, hard starting, or even the engine overheating because the fans aren't turning on when they should. Sometimes, it just throws a check engine light, and you'll notice if that happens. If it's really off, the computer might think the engine is always cold, so you’ll get terrible gas mileage. It acts like a shield, protecting your engine from damage caused by extreme temperatures.
