air flow sensor pigtail

Asked by Mssophia Nov 30, 2010 at 03:50 PM about the 2005 Nissan Sentra 1.8 S

Question type: Maintenance & Repair

My 2005 nissan sentra 1.8s has a bad pigtail from the mass air flow sensor. I have been to lots of salvage yards to attempt to find one..no luck. I recently called Nissan and was advised that you would need to purchase the main engine harness because the pigtail does not sell alone, $1500.00? I think not, for that price I can get another used car. Any suggestions, basically my car does not give me the gas I need to acclerate it used to cut off but I got that fixed, it also used to cut off when I reverse got that fixed too. I need a pigtail for my air flow sensor which has 5 pins with 4 being used...HELP HELP HELP!!!!

Keep in mind that its JUST A BAD CONNECTION. Its a very simple electrical problem that is cheap to solve if you have a friend who knows how to solder or crimp wires together. You have a bad connection somewhere in the MAF harness. One of the four wires coming out of the plug may be broken or its connection with the pin may be loose. Nissans are known to have issues with the MAF's pigtail harness ground wires. The solution is to move the grounding location of the MAF pigtail wires. If you have no clue what I'm talking about, bring the car to an auto electronics specialist (like someone who installs sound systems) and ask him to "re-ground" or move the MAF sensor grounding wires to a stock grounding location in the engine compartment. Hope this helps.

The ECU on some Sentras (or Nissans in general) actively grounds the MAF sensor, so bypassing ground just might cause problems in itself.
