![]() ![]() if its black that is most likely the problem. just behind the 3 glowplugs for the cooland on the r/h side of the engine ( if your standing facing your engine, hood up ) You should see a wire connection going to it, unplug it (just like the MAF connector ) and see what colour your sensor is. Our reliable mechanics will be able to diagnose a faulty coolant temperature sensor and replace if required.Check your coolant sensor. We specialize in diagnostic vehicle scans and repairs and can get it right first time. – Increased exhaust emissions: if the engine computer has an incorrect coolant temperature sensor reading there will be increased green house gas emissions from your cars exhaust pipe.Įngine coolant temperature sensor diagnostics and replacements in Hamilton:Īt Grimmer Motors we offer a range of car diagnostics and repairs. A damaged coolant temperature sensor could be responsible for a worse fuel efficiency and less mileage. – Poor fuel mileage: Fuel is expensive these days and a damaged coolant temperature sensor could be adding more cost to that bill. – Rough idling: If your engine is idling roughly or even worse to drive, it could be because the coolant temperature sensor is damaged so the engine is not making the correct air fuel mixture, or timing ignitions properly. You can tell this by the temperature gauge on your dash board if your car is equipped, or there may be an overheating dash warning light. ![]() – Overheating engine: If your engine is overheating it could be a sign that your coolant temperature sensor is damaged as your radiator cooling fans may not be coming on while idling or in slow traffic. – Check Engine light: This will turn on if the car computer detects a engine coolant temperature sensor. Symptoms of a damaged coolant temperature sensor: If this is the case, the coolant temperature sensor might be reading very high temperatures, and this fault code may appear. This means the coolant could have rust or corrosion and may not be cooling the engine properly. – Bad Coolant: If your coolant is old or you haven’t had a service or cooling system flush and new anti freeze in a while, your coolant might be stale and not performing correctly. The sensor may have corrosion, faulty wiring, or may not work at all. – Faulty coolant temperature sensor: The most likely cause of this fault code is just a faulty coolant temperature sensor. This indicates a high voltage from the coolant temperature sensor and could indicate an overheating engine. The most common fault code for engine coolant temperature sensors is P0118. If you find that your coolant temperature sensor is damaged, it would be best to get your car checked immediately, to prevent further damage. How serious is a damaged engine coolant temperature sensor:Īn engine coolant temperature sensor is an important component to stop your engine from overheating and damaging other components in your car. Learn more about coolant temperature sensors Please note some cars also have an electronically controlled thermostat, which rely on the engine coolant sensor data sent to the engine computer to control when the engine temperature by controlling how open the engine thermostat is. Using this data, the car adjusts the engines electric radiator cooling fan speed, and also may adjust the fuel injection timing and fuel to air ratio in order to make your engine run smoother and cooler. This gives an indication of how the operating temperature of the engine. The coolant sensor constantly tells the engine car computer what the temperature of the coolant in the engine is. About Engine Coolant Temperature Sensors:Ĭoolant (with antifreeze) is an important part of keeping an engine at a safe temperature, and sustaining the optimum temperature of your engine. ![]()
