Have Transmission Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
Hello again Chris here,
I wrote "Nothing on the engine will prevent the transaxle from engaging this is a trans concern. Are you planning to fix this yourself?" on the 14th but you never responded.
I believe there is transmission damage, the dealer has said there is transmission damage. You said the wheels are getting no power from the transmission. Although you say it is not the transmission to blame. I feel like the focus should be on what inside the trans has failed and how to address it. It is your car though and your time and money, if you want to go after other possible causes I will try to help you work through those, but I will not be able to say check X or Y or Z since I feel like that is going to lead you no further to a resolve.
So tell me what you would like to do, or what you want to check and I will help you do that.
So your question is how to test the MAF sensor?
Do you have a scan tool?
You can test an EGR valve by applying vacuum to it. If it makes the engine run rough then the valve is working.
On the MAF I would need you to back probe and tell me the voltage reading on each color wire while idling and I need your zip code.
Greensboro is at 702 - 850 ft. I will use that to see if your MAF readings are right.
