A car's intake air temperature sensor (IAT) changes the way it operates based on the temperature of the air in the vehicle's intake. If the IAT sensor is not working properly, it can affect the way its computer makes temperature based adjustments. A malfunctioning IAT sensor can cause seve...
The EGR sensor is a significant component within an exhaust system of the vehicle that observes the flow & composition of the exhaust gases which are recirculated back into the vehicle engine. So this helps the ECU (engine control unit) to adjust the operation of the EGR valve, which in tu...
Symptoms of a bad thermostat can be divided into two types:Thermostat stuck open: When the thermostat is stuck open, the engine temperature drops below normal when driving, especially on the highway in cold weather. A stuck-open thermostat can also cause a lack of heat from the heating syste...
ECM (engine control module) is an integral part of every vehicle to ensure that the car engine operates at optimal performance. There are many cases where your car has problems and cannot start due to a faulty ECM. Therefore, knowing the symptoms of a bad ECM and finding solutions to tackl...
Bad MAP Sensor Symptoms: Detecting The Issues The symptoms of a failing manifold pressure sensor are similar to the problems of low compression or improper fuel injection. These problems need to be detected beforehand, for avoiding any severe damage to the engine and its performance. So, here ar...
A temperature sensor installed close to the hot wire measures the temperature of the air near the hot wire. When the engine is idling, a small amount of air flows around the hot wire, so it takes a very low electric current to keep the wire hot. ...
The most common symptom of a bad engine control unit is an illuminated check engine light. It’s important to note that any malfunctioning engine component can trigger the check engine light, so it’s not always directly caused by a faulty ECU. ...
When there are symptoms of a Bad Engine Control Module, such as erratic engine behavior, reduced fuel efficiency, or failure to start, the problem often lies elsewhere. In many cases, these common symptoms can be traced back to a malfunctioning sensor or a faulty wire rather than a failure ...
rise. When the temperature exceeds a certain level, the sensor activates the electric fan which draws air through the radiator and cools the engine until the temperature is sufficiently lowered. A faulty sensor will not turn on the fan when the vehicle is stopped, causing the engine to ...
If your temperature gauge is reading in the red, you shouldstop driving immediatelybefore more serious problems appear, like a blown head gasket or engine seizure. While other issues like a coolant leak can cause high engine temperatures, it can be caused by a bad oil pump. That said, you...
