If you do not have an OBD-II tester, and are not familiar with meter's, then simply disconnect the electrical connection at the MAF sensor. If car runs worse, it is probably the sensor. If no change, the problem exists somewhere else. The sensor is located in the air intake duct. Note: The Mass Air Flow element is a sensor, not a module. various sensors throughout the car's Emissions system send singles to the PCM (Power Control Module), which in turn controls proper engine performance. most sensors are basically like an on and off switch....

Why is a highly coupled module difficult to unit-test?
Unit test can be done within a single module Cohesion of a single module/component is the degree
Why would your 1997 Oldsmobile cutlass backefire and sit and sputter when you press on the gas?
If the check engine light is or has illuminated we need to know the code(s). The ignition module is one possibility. The MAF (Mass Air Flow) sensor is another. Try cleaning the MAF sensor with MAF sensor cleaner. Use Only MAF sensor cleaner and follow the directions on the can.
Will the module test good after it has cooled off?
It depends on which module you are talking about. But yes, I've had them test good cool and bad hot.
What are the main problems with 95 buick rivieras?
Crank Pulley, crank sensor, ignition module, dirty maf sensors, clogged fuel filters.
How can you test the ignition modual?
ignition module on what?
Where is the control module on a1999 silouette?
The control module is located under the air cleaner box. Carefully remove the the upper air cleaner enclosure, MAF sensor and rubber duct. Remove air cleaner and lift compartment lid. Computer control module is there. Hope this helps?
What is a stub?
Stus are nothing but the replacement for the modules which are subordinate to module under test. These dummy modules use subordinate module's interface & do some data manipulation, Print the verification & Return control to the module under test. e.g Suppose I have 3 modules viz, module1,module2 & module3 & I have to test module 2. Module 2 is ready but module3 is not ready so we will create a dummy module for module3 which is called as stub. Also we can say that Stub's are nothing but the called functions. These are also called as test harness tools.
How do you test the ignition module on a 91 merc capri. Auto Zone and Napa could not test.?
Answer testing ignition modulenot all part stores have the ability to test ignition modules,a sure sign would be discoloration of the module or if the outside of the module has a softness to it if neither is apparent you could go to advance auto stores and they do have a peice of equipment to test your module, I used to work at a advance auto parts store
How do you check the Mass air flow sensor on a 1993 ford ranger?
unplug it, if there is no change in how the engine runs it may be bad. the only for sure way is to test it on a sensor tester. There are some MIL codes that will lead to a faulty MAF p0102 maf signal low input p0103 MAF signal high p1100 maf circuit output low during self test p1101 maf sensor circuit output low during self test A few that arent so obvious Lean or rich codes fuel trim codes serious lack of power when accelerating lousy gas mileage rough idle or stalling Look for vacuum leaks between the maf and throttle body and dirt or fuzz on the two wires on the sensor itself, these two items are the easiest to cure. Clean the sensor with electrical contact cleaner or maf sensor cleaner, but dont touch the fragile wires, they break easily.
