My 85 Z28 and EPROM Project 85 ECM wiring (MAF/MAS) diagram copy1/copy2 86 ...Wiring Diagram 8 1 Gm Mas Air Flow - Rounding out our LS1 engine guide is our LS1 ECU pinout article for year ranges between 1999-2002 F-body vehicles. This ECU pinout is accurate for 99-02 LS1 engines with cable actuated throttle bodies, and is not accurate for the Chevy Corvette.. Wire Harness Installation Instructions For Installing: Part # 60101 - GM 87 & Later TBI Standard Harness Part #60102 - GM 86-89 TPI Mass Air Flow (MAF) Standard Harness Part #60103 - GM 90-92 TPI w/Speed Density (MAP) Standard Harness Part #60201 - GM 87 & Later TBI Extra Length Harness. MAF Sensor Wiring Diagram NOTE: The mass air flow (MAF) sensor wiring diagram and info in this page apply to specific Ford vehicles/model years. Take a look at the Applies To: box on the right column to check for specific application info..
General Motors tuned port (5.0L and 5.7L) injection engines. This includes all wiring that is needed by the computer to run and control the fuel injection system. Most of the wiring in the harness has been pre-terminated to the proper connector and all wire is rated at 125°C and has been GM color-coded.. The part number of the LS1 MAF we are testing is usually GM 25008302, although many different versions of this Mass Air Flow Meter exist. Scroll down to the bottom of the page to check out the other part numbers for the many MAFs that you can select from GM trucks, vans, and other vehicles..

May 01, 2010 · At the Mass Air Flow (MAF) sensor connector, backprobe the Gray (GY) wire at terminal #6 with the key on and the MAF sensor connected. Typical voltage will be about 2-3.5v depending on temperature. 2.. Ill check out the output voltage at the ECM and its ground and go from there, I just figured all the 5V ref were on the same circuit, but after looking at the wiring diagrams I can see they come out of all different pins. Ive diagnosed things like this before. I just didn't have the diagrams to check it out.. In 2001, GM changed the format of the mass air flow meters on C5 Corvettes. In previous years, the MAF (Mass Air Flow) meter and IAT (Intake Air Temperature) sensor were 2 separate pieces, both having their own wiring connector..
There would be a Intake Air Temperature sensor that is located in the rubber boot to the throttle body. And depending on the year of your vehicle, there could be an Idle Air Control Valve, that is just past the MAF sensor and on the throttle body.. My mass air flow sensor on an 88 Camaro 2.8 reads 5-volt reference between signal and ground while running and unplugged, on the ECM side, at idle. Shouldn't the mass air flow sensor dictate the voltage going out to the ECM? While plugged in, there is erratic non-detectable voltage, on/off, on/off.. The mass airflow sensor (MAF) measures the amount of air entering the engine. The OBD-II code P0101 is set when the signal from the mass air flow sensor is out of expected range, or in other words, the MAF sensor doesn't work properly..
The MAF (mass air flow) sensor is a sensor mounted in a vehicle's engine air intake tract downstream from the air filter, and is used to measure the volume and density of air being drawn into the engine.. Mass Air Flow (MAF) Sensors The Mass Air Flow Sensors converts the amount of air drawn into the engine into a voltage signal. The ECM needs to know intake air volume to calculate engine load. This is necessary to determine how much fuel to inject, when to ignite the.
