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...
In particular, the sensor is stuck with too much dirt or grease which is the main cause that causes the ECU to misinterpret the input signals. In addition, this sensor is also affected by the high temperature of the engine for a long time without being replaced, which also easily leads ...
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. ...
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 ...
Firstly, the compressor, connected to the engine via a high-pressure line, adsorbs the refrigerant in the gas form from the gas tank and compresses it at high pressure. When it is compressed, the refrigerant temperature rises and it is pushed to the condenser, located at the front of the...
This is especially true of the transmission fluid, since low fluid can cause low pressure, which will not allow the transmission to operate properly. #2 – Sensor Malfunction There are quite a few sensors which control the engine and transmission. If one of the sensors, such as the MAF, MA...
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 ...
You DO have white smoke coming out of the exhaust pipe??? Does the engine miss-fire and run bad and does the check engine light come on? Are you continually adding coolant to the radiator?? I would expect all these things to be happening if you had a blown head gasket or an ...
the freeze frame of the parameters (engine temperature, vehicle speed, fuel trim readings, etc.) at the time when the code was set. Typically, the code P0171 is set when either short term fuel trim (STFT) or long term fuel trim (LTFT) adjustment exceeds a certain value (usually +25%...
