Code P2097 SOSpls Hello friends.

. As well as the engine size codes stored and symptoms exhibited it. Dirty cabin air filter mostly only leads to reduced cooling. Rich of stoichiometric the HO2S will generate a voltage between 045 and 10 volt.

1998 Mercedes Benz CLK320 Base 6 Cyl 320L. If only hot air comes out of the air vents in your Elantra then the problem probably lies somewhere else. Most of the time these Mercedes-Benz fault codes are caused by a defective Mercedes Mass Air Flow Sensor MAF sensor.

The easiest way of testing the MAF sensor is by monitoring the voltage signal from the sensor to the PCM on a scan tool. Youll be shown up to 3 possible. If a scan tool is not available then test the signal coming from the MAF sensor with a digital volt ohm meter.

The mass airflow sensor MAF measures the amount of air entering the engine. Symptoms Causes. Start with what you see hear smell or feel.

Mass Air Flow Sensor Replacement. 2013 nissan sentra code p2097 Check engine light is on. The more air the greater the heat loss.

A faulty mass air flow or manifold air pressure sensor Defective O2 sensor s Burnt chafed broken or disconnected wiring and or connectors Engine exhaust. Like the radiator the air conditioning condenser on Hyundai Elantra sits at the front of the vehicle and is responsible for releasing the heat from the refrigerant into the. In most cases this code is not very difficult to diagnose.

Therefore the ECM must supply more electric current to maintain the temperature of the hot film as air flow increases. Check your owners manual to locate the MAF sensor for your specific car. Code P2097 has appeared.

The quickest way to check if your Mass Air Flow MAF sensor is the problem is to disconnect your electrical harness while your car is running. What is the most likely problem. If you can locate a technical service bulletin TSB that matches the vehicle year make and model.

Lean of stoichiometric airfuel ratio of approximately 1471 for gasoline engines the HO2S will generate a voltage between zero and 045 volt. Replaced the O2 sensor. INSPECT MASS AIR FLOW MAF SENSOR.

The HO2S sensor senses the oxygen content in the exhaust flow and outputs a voltage between zero and 10 volt. The Diagnostic Trouble Code DTC will be set when the ECM detects a high or low voltage from the sensor under normal. Remove the mass airflow sensor and clean the sensor using mass air flow cleaner or contact cleaner.

Therefore the ECM must supply more electric current to maintain the temperature of the hot film as air flow increases. 2005 Acura TL Base 6 Cyl 320L. The ECM detects the air flow by means of this current change.

Mercedes-Benz owners may notice the check engine light plus P0170 and P0173 codes. How to clean your MAF sensor. If mass airflow MAF manifold air pressure MAP or intake air temperature IAT codes are stored these should be addressed before attempting to diagnose the stored P200A.

Dirty or clogged condenser. If you find any leaks have them. Check the exhaust system components for leaks before the Air Fuel Ratio Sensors or Oxygen sensors.

Trouble code is p2097. The Diagnostic Trouble Code DTC will be set when the ECM detects a high or low voltage from the sensor under normal. Easy QA about symptoms to help you understand what could be wrong with your vehicle.

In theory these two codes mean that the fuel mixture is too rich or too lean. The more air the greater the heat loss. We will need to test the Mass Airflow Sensor or MAF sensor as it is a major airflow input to the PCM.

The OBD-II code P0101 is set when the signal from the mass air flow sensor is out of expected range or in other words the MAF sensor doesnt work properly. You can try cleaning the sensor but that doesnt always work.
