I just made my last payment on my 96 MAX and its having problems. Flawless for years now and now this.
Can anyone tell me what these trouble codes mean:
-MAF/VAF circuit malfunction
- Serial Comm Link Malfunction
- Gear 1 ratio incorrect

Any help on this would be so great. Thank alot folks!!

 

this is the wrong forum, try the 4th gen forum.

 

What the hell? A poll?

 

Well I don't know where the heck you got those reports from but they don't even appear in the ecu codes report I have. Use the correct scanning tool for OBDII or retrieve them yourself.

I looked in Hayes book and your right. i couldnt find them there. But I was with the guy at Autozone when he scanned my car with the scanning tool. i saw and wrote down the errors that appeared on the handheld.

 

I don't know about all that, but cool Screen Name.
"How's the Magician's Nephew" doing? ha ha

 

i choose HELP in poll.....hope that helps.....

 

I schedule an appointment with Nissan tomorrow. I know im goin to get robbed there. Dont know whatelse to do. My MAX is hesitating so bad its not funny. Wish me good luch tomorrow......

 

Get an estimate and find out what parts you need. Then come here to find out where to get it cheaper.

 

i've got some easy steps for you to follow:

1) cancel your appointment at the dealer.
2) read the faqs and find out how to check the codes yourself.
3) read the faqs again (see how helpful they actually are??) and decipher your codes.
4) fix it yourself because you can, and you won't need to buy any lube for your trip to the dealer.

hope that helps

 

i agree read up and dont go to the dealership. The autozone handheld is not the greatest i'd rather listen to the ecu. Who knows it may even be your Knock sensor. all i say is read up or pay up.

 

Thanks everyone for helping. I am embrassed to say but all the problem was a piece of the air filter came off and got stuck so that the air mixure sensor was faulting in the car. That cause the MAX to hesitate. I $20 part costed me $117 for part and diag at the dealership.
I plan to now my MAX inside out since I been laid off from work. There are a couple of cheap things I want to do to my car.
First I was told to get to the tranny fluid asap. I will do that tomorrow. I guess i have to buy those stands for the car. I just hate lifting my car on a slant and not all the oil coming out before adding new oil. Am I just being paranoid??

Thanks agian everyone for helping me out giving me the encouragement to work on my MAX problem myself.

 

It's nice that you finally fixed your max, but now, you may want to fix all your spelling errors, grammar.. it's pretty hard to understand all that what you wrote.

In any case, good luck.

 

This is the closest one I can find
0102
Diagnostic Trouble Code 0102 points to a problem with the Mass Air Flow Sensor. The MAFS is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a thin film that is supplied with electric current from the Engine Control Module. The temperature of the hot film is controlled by the ECM a certain amount. The heat generated by the hot wire is reduced as the intake air flows around it. The more air, the greater the heat loss. Therefore, the ECM must supply more electric current to the hot film as air flow increases. This maintains the temperature of the hot film. The ECM detects the air flow by means of this current change.

This malfunction is detected when an out-of-range voltage is sent to the ECM. That voltage might be too high or too low.

a) An excessively high voltage from the MAFS is sent when the engine is not running.
b) An excessively high voltage from the MAFS is sent under light load driving conditions.

Possible causes include...
- Harness or connectors (the sensor circuit is open or shorted.)
- Faulty MAFS

c) An excessively low voltage from the MAFS is sent when the engine is not running.
d) An excessively low voltage from the MAFS is sent under heavy load driving conditions.

Possible causes include...
- Harness or connectors (the sensor circuit is open or shorted.)
- Intake air leaks
- Faulty MAFS

With DTC 0102 the ECM is supposed to switch into Fail Safe mode and limit engine speed to 2400 rpm.
