Ran codes and determined Mass Air Flow was out. Replaced it myself. ECL is still on and car still hestiates at acceleration, hill climbing, etc. Will ECl cycle off and will ECM reset itself or what to do? Help guys.

 

it should have been solved when you connected it are you sure it was installed properly or are the connector wires loose. and its CEL

 

humm intersted of the outcome of this issue

 

What were the codes that lead you to the MAF?
Check the electrical connection, more specifically the connections within the connector itself. Look for lose, frayed or corrosion on both sides of the connector.

 

Did you replace with an aftermarket or used OEM MAF?

 

Did you try and clean the OEM MAF? Take some MAF cleaner and spray the heck out of that little wire inside. I took an acid brush and cleaned the heck out of it. That little wire in there is more robust than I thought it would be, in fact its real solid.
That worked wonders for me.

Another thing to check with MAF. When you remove the MAF ftom the manifold, there is a round rubber piece between the MAF and the intake. Nissan calls it an "isolator." If it is hardened or cracked, it will also need to be replaced. Costs about $10 at the dealer. If the isolator is bad, it will leak unmetered air into the intake behind the MAF, thus confusing the ECU. I didn't realize it was bad on my car until I was actually changing the MAF; had to run up to the dealer and get a new one.

 

i do not recommend this to anyone. when cleaning your MAF, be a gentle as possible. you can murder your $400 part with the method you posted.

 

also this. my boys max just got scanned for a MAF light. his "isolator" was completely dry rotted to the inside of the intake. when we removed it to clean it we pretty much had to rip the "isolator" in half. for some reason though the "isolator" is listed as an "insulator" on courtesy parts.

 

Do you have to reset the ECU? I popped a cheap one in from the JY and it drove better but now my car can't go past 2000 RPM

 

shouldnt have to i think

 

Nope.

 

old thread, new post. got a p 0100 which is the code for maf. thanks to cs ar i got a replacement one. seems simple enough, but what do i have to remove before putting the new one on? write-up somewhere in here, video? sorry, i'm tired and the max is idling like crap.

 

Just leave car off, open hood, disconnect wire harness from MAF and loosen both clamps on either end to slip out. Make sure the rubber insulators are good and install new MAF and reverse the steps I just mentioned. My MAF seems to start going out as it randomly stalls coming to a stop sometimes but no code yet.

 

got it off and this was ripped up
