Subaru Maf Sensor Wiring - 1996 Subaru Legacy 4 cyl Automatic this car is driving me nuts. Replaced MAF 3 times, ran o.K. For 2 days now acting up again. MAF code still coming up.. Sep 16, 2015  · Gc8 maf sensor problem help. Dunno if Mao is still on here (cbf checking), but his stock was the genuine article which is supplied to Subaru, same part# and all. In any case, there is some good info on there. I feel your pain re the '99 AFM, they are too darn sensitive, and I've replace a few in my time. gc8, maf, problem, sensor. The Mass Air Flow (MAF) sensor measures the amount of passing air going through the air intake system. The sensor measures the amount of passing air with a resistive platinum wire that is placed in the air stream of the air intake system..

2002 IMPREZA SERVICE MANUAL QUICK REFERENCE INDEX WIRING SYSTEM SECTION This service manual has been prepared to provide SUBARU service personnel with the necessary information and data for the correct maintenance and repair of SUBARU vehicles.. The ISR (Formerly ISIS) Performance Nissan air flow sensor is vital if you install a turbo upgrade on the SR20DET or KA24DE. Keep in mind that this is not something you can just bolt onto a stock 240. This is an upgraded MAF that is designed to be used with a new turbo setup, larger injectors, a larger turbo system, and other upgrades.. 4 wire map sensor, mass air flow sensor cleaning. how does a mass air flow sensor work. subaru mass air flow sensor. mass air flow sensor replacement. crankshaft position sensor symptoms. bad mass air flow sensor. ford air flow sensor problems. elite mass flow sensor. mass flow sensor burick rena. bosch mass air flow sensor. electrostatic mass.

1 WIRING DIAGRAM BY MODEL This document describes car models to which the AFC neo (Product code: 401-A917) is applicable, and ECU terminal arrangement drawings.. A hot wire MAF sensor uses a platinum wire located in the path of air flow, which is heated using specific voltage. As the air passes over the hot wire, it is cooled, decreasing the wire. Apr 01, 2008  · I want to make a note, the OBD2 code database for this site, does not mention that cars can stall with a bad MAF, neither does any other database I looked at. I do not know if this is a thing that is unique to Subaru but if you have a stalling Subaru yet can be restarted immediately, it may be your Mass Air Flow sensor..

Since your engine most likely came with automatic tranny, you need to remove wire #2 from the mass air flow sensor (this connects to pin 47 of ECM). You also need to supply a ground wire to pin 81 of the ECM. Auto tranny wiring harnesses don't have a pin at that location, so I just stole one from an unused wire. Subaru has since changed. An Intro to Subaru Tuning Bad Noodle Page 6 23/04/2009 Which tables to tune When you first see all the tables in the ECU through RomRaider, you might wonder what they do and which ones you need to change. Luckily, there are descriptions for each table. Open the table and look at the description under View Table Properties.. 2002 - 2004 Subaru Impreza WRX ECU Diagram. 2002 - 2004 Subaru Impreza WRX ECU Diagram . Printable (PDF) version.

The other wire should be connected to the ECU's sensor ground. That would be pin 92 (black) on a 2G ECU harness or pin 24 (green w/black stripe) on a 1G ECU harness or pin 72 (black) on an EVO1-3 ECU harness. This can also be pulled from the MAF connector under the hood. The wire colors are the same on the MAF connector as on the ECU harness.. These are the pinouts for the US Spec 2002 WRX Turbo ECU, as provided to me by a fellow NASIOC member, Jon Schmidt. An explantion of the wiring color schemes is given at the bottom of the page..
