Mar 23, 2022 · When the trouble code P0401 is set, exhaust gases are reintroduced to the combustion chamber at the incorrect time or in incorrect amounts, which does not decrease the oxygen level enough to prevent the increase of NOx. This is likely due to a faulty or clogged EGR valve or carbon buildup in the intake manifold or on the EGR temperature sensor. 1. Check Engine Light: Engine Check Light. Check engine light is one of the most common symptoms of bad IAT sensors. The check engine light is located on the dashboard of the car. It lights up when the IAT sensor of the car is facing any issues. All the sensors of the car are connected to the ECU of the car. The symptoms are a long cranking time and a very rough running in the first several minutes. Although changing them is a relatively simple job, remember that a stuck glow plug can break while removal attempt. You will need a plug removal tool in this cause. Glow plug module can go bad, as well. ConclusionA strong smell of gasoline means you either got a leak somewhere around the gas tank - vapor escaping, OR your Oxygen sensor(s) / Engine Coolant temperature sensor has gone bad. If you have a OBD II scanner that can read live data. connect it to the OBD II port & check the readings on your Oxygen Sensors along with your Short Term & Long Term ...The engine control module (ECM) uses this sensor to constantly measure the engine's temperature. It is then able to regulate the fuel levels and idling, so it can adjust the spark as well as the exhaust gas regulation (EGR) valve functions. So if your ECT sensor does go bad, there are a few symptoms that will help you pinpoint the problem.Below are some common tale-tell signs that your Mass airflow sensor has a problem. 1. Emission of excess exhaust fumes and black smoke. If your car emits excessive exhaust fumes, it may be a red flag for a faulty MAF sensor.

May 24, 2021 · Pre-OBD2 Asian vehicles are often fitted with a two wire EGR temperature sensor that will report hot exhaust gas when the valve is open – or the lack of hot exhaust gas if there is no flow. These feedback methods are all about closing the loop. OBD 2 systems are required to monitor EGR flow and store a P0401 code if exhaust flow is insufficient. This MAP sensor is mounted directly to the intake manifold, but others might be connected by a hose. Benji Jerew/Flickr/CC BY 2.0. The ECM uses MAP sensor data to run crucial calculations, such as engine load, fuel injector pulse, and spark advance. When at rest, the MAP sensor reads atmospheric pressure at sea level (29.93 in. Hg).When the sensor fails, your engine will no longer be as efficient. Below is a list of the most common symptoms that you may experience: Poor Gas Mileage When you first start your car, the computer uses information that it receives from the coolant temperature sensor. This can lead to a rich-running engine.The exhaust gas recirculation (EGR) system works to lower temperatures and reduce nitrogen oxide emissions. The gas emissions will form when the temperature reaches about 2500 degrees Fahrenheit. The EGR sensor main work is to get small amounts of exhaust fumes back to decrease the temperature and ultimately decrease combustion.In Canada, the exhaust temp sensors go for $150, and IMO that was just too much to ask.
