11/12/2009· My mechanic thinks it may be the MAF sensor, but isn''t sure. My question: can I unplug the MAF sensor and drive the car, for the purpose of seeing if the symtoms change? the symptoms: Driving the car under load, it hesitates. Classic feel that you get when spark plugs start going bad. I installed new double platinum plugs, and got a replacement set of GM wires …

Answer (1 of 4): Yes you can you will just get horrible gas mileage. When you have a bad mass air flow sensor or dirty either way if the check engine light is on from a mass air flow sensor OR a 02 sensor the computer puts the vehicle into open loop mode. What open loop means is DME is ignoring t...

Should You Keep The Mass Air Flow Sensor Unplugged? The mass airflow sensor is unplugged to check whether various components are working fine. It’s true that in case of a faulty mass airflow sensor, unplugging it might make the car run better. But this is not a longterm arrangement you should rely on. The tables programmed into the computer contain values …

1. level 1. ShredShredChugChug. 1 year ago. When you unplug your MAF sensor the computer defaults to reading other sensors to measure air intake. The main ones would be your O2 sensors on your exhaust. Driving without your MAF can eventually lead to a failing catalytic converter as well as a few other thing.

The mass air flow sensor is a possibility...try leaving the mass air flow sensor wire harness unplugged to see if the car runs better. If it does, probably it is bad. However, I would also check the exhaust for a restriction (eg. converter could be plugging up), one way to check that is to hook a vacuum gauge to the engine to see if you get normal values. (vacuum should hold …

2) Mass Air Flow sensor (MAF). If it runs fine with it unplugged its most likely your problem. Replace it with a new ACDelco unit or get an ACDelco from the junk yard. 3) Check fuel pressure and fuel pressure regulator valve. 4) Check coolant temp sensor. 5) Check crankshaft position sensor.

29/12/2010· Idle roughly, but steady. At very slight throttle pressure (barely more than coasting) it can be jumpy, from 500 to 1500 rpm. Got fault code 08 Air Mass Sensor (keep in mind, this ONLY shows when MAF is disconnected. If MAF is plugged in, I get misfire codes and recently coolant thermostat jammed open.

03/08/2006· Many modern cars don''t have air flow meters anyway. Interesting. Nick . I didn''t imagine what I heard. Badger00 Distinguished Member. Jul 3, 2006 3 It will possibly mess up your fuel consumption and cause some power loss. I''m guessing because it''s duff, it''s seeing insufficient air coming in, which in turn is limiting fuel intake. Either that, or it''s not opening the throttle fully. I''m not au …

02/03/2020· Similarly, why would a car run better with the mass air flow sensor unplugged? Because either the sensor is reporting incorrect air amount and or air temperature to the ECU. By disconnecting the sensor the ECU switches to limp mode and the car may idle better. Some MAF sensor wires can be cleaned and some cannot as the wires are not easily accessible . …

22/11/2004· Yes You can drive the car with the MAF unplugged. The ECU will Use default values and use RPM and other things to compensate. In fact that is one of the test you can do to determine if the MAF is bad, if the car stumbles doesn''t run right with it plugged in and maybe you have a 121 code, unplug it and if it runs OK then pretty sure bet the MAF ...

18/03/2018· Mechanic tells me I need to remove and replace mass air flow sensor, but I unplugged it and the car shut off so is that not the problem? On other forum someone was having the same issue as I and said it was his cam shaft postion sensor that was the problem. Just wanted advice so i don''t pay for something that won''t fix the problem. My car has 169000 …

22/02/2021· What Happens If You Disconnect Mass Air Flow Sensor? So, since the mass airflow sensor is used to measure air intake into the engine to keep the car running correctly, then what will happen if you unplug the sensor? Will the car die or stop running? Well, the answer to that is no. If you disconnect the mass airflow sensor, then the car should keep …

14/05/2020· How to Disconnect the Mass Air Flow Sensor? Step 1: Park and Cool Down Your Car. Step 2: Find The Location of the Air Flow Sensor. Step 3: Trace the Air Flow Tube and Find The Connection. Step 4: Remove the Bolts. Step 5: Find Electric Connections. Step 6: Disconnect the Electric Connection. Step 7: Lift the Sensor from Its Place.

08/09/2010· Most likely if there is no mass air sensor you actually unplugged the inlet air temperature sensor IAT. This is a little bead like thermistor that sits in the ducted air stream to measure incoming air temperature. Without an air mass sensor your engine will have instead a manifold absolute (air) pressure MAP sensor. This measures the absolute air pressure (the …

01/08/2021· Answer (1 of 3): Go right ahead. Without a MAF reading, the computer will use a preprogrammed alphan tune (alpha being throttle position, n being rpm). It will not compensate for things like altitude (which influences the air density) and possibly air temperature (se have the temp sensor integr...
