Is there a way for me to check to see if my wires that run to my MAF sensor are bad by using a multimeter ? Thanx guys !

 

ohms/continuity check. bend/move wires while taking readings to check for shorts/opens.

 

check make sure your cooling fan is working, mine had stoped working and didnt notice it much in the cold...try that and see what u come up with

 

how man ohms should it be reading ? thanx guys !

 

put the meter on DC (thats common sense but thought id add it) as long as its gettin a reading its got power

 

Do a search for my code 34 chart, that checks all the wires out, too. To do resistance checks of any harness wires, youll need to have both ends disconnected- in the case of your MAF, the harness wire needs to be undone at the MAF and the relay/computer/ground/etc. Otherwise, if the wire has power, and you try to read the resistance/continuity of it, you could fry your meter.

89cmrodriver has a good idea too, just check for +12 or -12 volts. This should be much easier- but you'll need to know which wires to probe to get +12 or -12 volts. And the magic voltage level for the MAF signal wire is in my code 34 chart...

 

the wire that is the lightest color one has the load on it, cut it, strip it and check it with the car running, other wise it will not have a reading...lol..common sense again

 

I dunno about the rest of you guys, but cutting my MAF wires at any point just doesn't fall under "common sense"... common sense dictates use needle-tip probes that will unobtrusively puncture the wire's insulation.. or even use 3 jumper wires instead of directly plugging in the harness, and leave a patch bare on one for testing.. anyone with ""common sense"" want to argue?

 

im talking about the cooling fan wires....but really u can cut any wire and wire nut it back together and put electrical tape around it for a good sealent

WRONG.
By my past place in Marina Del Rey and even further inland, the corssivness of the ocean salt air, eats that idea right up.
Solder connections, use heat shrink wrapping for true secure patch.
It is lots of extra effort.

 

Wire nuts?! You're *never* working on my car. Alot of these sensors are precision instruments. 1 ohm of added resistance will screw up the readings and rob you of power. Karl's completely right. His reason is quite valid too, however, it goes further that a good solder job should leave the wire with negligable added resistance.

MEANING, why'd ya cut it in the first place?

I had to do a wire patch in my starter wires for my Blazer (the fusible link wire). I did exactly what I said above.

Hacking wiring jobs cause so many problems.
My 1974 Corvette came with a wire harness like that.
The previous owner had a hot power lead basically grounding on the metal dash of the center console.

Can you say "FIRE HAZARD!"
