GM TPI WIRING Mass Air Flow harness for modified GM Tuned Port Camaro/Firebird/Corvette 5.0, 5.7 Engines (1985-1992): Excellent choice if your engine has been modified with a larger cam or higher compression and you are concerned about vacuum.. MAP Sensor . This issue I am going to explain the MAP (Manifold Absolute Pressure), MAF (Mass Air Flow), and IAT (Intake Air Temperature sensors and their functions. The MAF or Mass Air Flow sensor (if present) is the main sensor used by the ECM to determine Fuel Delivery. so can faulty wiring. MAF sensors that output a frequency signal.
Nov 24, 2017 · This to me is screaming a wiring problem - might not even be related to the MAF wiring. Could be an intermittent fault in the 5v ref, ground, or power either to a sensor, or to the ECM. Lots of possibilities, and condemning the ECM is the LAST step in a long process.. Hot-Wire-Type MAF Sensors. such as the AC Delco MAF on some General Motors' products. To check the MAF sensor's voltage signal and frequency, connect a voltmeter across the MAF voltage signal wire and ground wire. Start the engine and observe the voltmeter reading.. Sensor Connector Kits. Sensor connector kits are available for popular replacement connector applications. Our kits include all of the necessary cable seals, terminals, secondary locks, clips, and dress covers. Connector Kit for GM 3 Wire Mass Air Flow Sensor (MAF) Delphi Metri-Pack 150 Parts to build your own connector assembly: $7.50:.
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.. MAF Diagnostics with a multimeter Basically all MAF sensor have 4 wires. Some have more and if so those extra wires are for the intake air temp. sensor that has been incorporated into the MAF housing.. The MAF Translator is a conversion interface to allow the use of late model GM Mass AirFlow (MAF) sensors on Mitsubishi DSM (Eclipse,Talon,Laser) vehicles. The late model GM MAF sensors offer lower intake restriction than stock which boosts horsepower and improves turbo response..
So if you measure the 3 wires, just eliminate the 5 volt wire and the 0 volt wire, and the remaining wire is the signal wire. This is slightly complicated by the fact that many MAF sensors today also include an Intake Air Temperature sensor in the same housing.. P0102 Mass Air Flow MAF Circuit Low Technical Description. Mass or Volume Air Flow Circuit Low. What does that mean? This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles that have a mass airflow sensor..
