How does the MAF work with the O2 sensor?
The MAF is sometimes used in conjunction with an O2 sensor that provides a “closed-loop” feedback in order to make corrections to that predicted air mass. Engines need a proper blend of air, fuel, and combustion to run efficiently.
Can a bad O2 sensor be a bad ECM?
The ECM controls the heated oxygen sensor heater element. It controls the heater element circuit by allowing current flow to ground. So, your P0135, could be a bad sensor, but also a bad ECM etc. I would suggest that you replace the O2 sensor and then recheck to see if it clears the error.
What happens when you disconnect mass air flow sensor?
That is because the numbers the computer generates are for brand new engines, and conditions change with the engine as it ages. By letting the mass airflow sensor make the readings, it allows for the most accurate numbers if it is working properly. So, now you know what happens when you disconnect the mass airflow sensor.
What kind of Fuse does an oxygen sensor need?
No. 4 A/F SENSOR (15 A) fuse in the under-dash fuse/relay box. No. 23 IGP (7.5 A) fuse in the under-dash fuse/relay box. Also, Oxygen Sensors need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor.
What are the problems with the MAF sensor?
The two most common trouble codes in relation to the MAF sensor are: Ford F150 P0101 Diagnosis: MAF Sensor Ford F150 P0102: MAF Sensor Circuit Low There are other codes related to the mass air flow sensor as well, but these are the most common ones.
Can a car run without the mass air flow sensor?
The mass airflow sensor is a key sensor in your car. Your car has a lot of sensors, and this is just one that helps your car run properly. That brings up the question of can your car run without the mass air flow sensor? In this article, we will look at what happens when you disconnect the mass airflow sensor.
That is because the numbers the computer generates are for brand new engines, and conditions change with the engine as it ages. By letting the mass airflow sensor make the readings, it allows for the most accurate numbers if it is working properly. So, now you know what happens when you disconnect the mass airflow sensor.
Where is the MAF sensor on a Hyundai Elantra?
Uses mass airflow sensor cleaner. It’s really cheapand available at any parts store. It sure beats the heck out of having to buy a new sensor. Locate the MAF Sensor– It’ll be in between the air filter and the throttle body.
