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
The job of a thermostat is to help the engine warm up faster and maintain the engine temperature above the minimum operating temperature (194°F or 90°C). A conventional thermostat is a simple temperature-controlled two-way valve that opens at a specified temperature. In most cars, a thermo...
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 ...
A speedometer may stop working due to a bad sensor. Plus, the affected cruise control can disrupt the driving functions of the car. Any problem with the sensor will make the Check Engine light come on. Issues with the ECU The Engine Control Unit (ECU)is literally the hub of engine activi...
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...
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...
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%...
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 ...
If the EGR system is clogged up, or the valve is stuck closed, the combustion temperature increases. This may cause pinging (detonation), as well as surging on light acceleration. In a diesel engine, a bad EGR valve is one of the causes of a black smoke. The Check Engine light might ...
