Today I was on my way to work at the usually 4:40AM and my car decides to throw a check engine light and not rev past 2,300 RPM. Well I thought it could be my oil catch can because I have yet to replace the hose that supposedly melts. I messed with that and it now revs fine and drives fine. I got the code pulled at Advanced Auto and it is P0102 - Mass Air Flow Sensor Circuit Low Input.

I have a VAFC-II and was maybe thinking the wiring could be at fault??? I do not think so but am not sure what circut low input is all about. If my maf was shot or blown wouldn't I not be able to rev past 3k?

Also, When people upgrade to the landrover MAF does it come with the sensor inside or is just the housing? Maybe this is a good time to do the upgrade.

 

Okay, I replaced the MAF with a 2001 and replaced the transistor. That didn't work. I unplugged my VAFC and reconnected the MAF wires - all wiring is stock now. That didnt work.

The light is still on but the car drives fine, I tried resetting the ECU but that didn't clear it. I went back to advanced auto to get the code pulled and its the same

P0102

HELP!!!!!!!!!!!!

Maybe you should post it again.

 

Look, I really need help and there was like 10 posts after mine in the Newbies thread. I only have one car and mine shut off on me while I was driving, I lost power steering and eveything. I don't want that to happen again. Telling me what I already know isn't helping.

 

At least follow the rules (you're not a newbie)-we aren't at your beck & call.
I'm surprised switching the MAF didn't-did you check the hoses, lines, etc.

Ok, I'm gunna try some of that. Any other ideas?

 

The light is still on, but the car has been driving fine back and forth to work for the past few days. Any ideas?

 

have you tried clearing it? it might just be a stored code now...

 

its a stored code
two options -
1. get the code cleared
2. drive for a few more days. if the problem is fixed, it will go away

 

Another question. If the code is stored, wouldn't resetting the ECU clear it?

I have reset the ECU a few times with no luck.

 

Correct. Reseting it would clear it. No dice, looks like its not stored. I hope you get it all figured out.

 

I cleared it today at advanced auto, I dunno why the ECU reset didn't. Maybe I didn't do the ECU reset right. But I am relieved now.

 

No. As sooner said it's a stored code. Resetting the ECU will not clear those type of codes.

I went through the same thing when I replaced my MAF. Driving the car for a couple of days cleared the code.
