Genuine Delphi GM Original Equipment Manufacturer - OEM 2 wire Metri-Pack 1502 connector replacement pigtail for many GM Intake Air Temperature IAT Sensors.

Gm iat sensor wiring. 15C 27F. Disconnect the DB37 at MegaSquirt and check the resistance from harness pin 20 to ground pin 7 ie the IAT sensor reading if it is between 100000 and 200 Ohms you should get a temp reading. Assembled with 12 inch lengths of automotive TXL wire.

We can also do a 48 inch version which works for applications with a Front Mount Intercooler or any setup that the IAT sensor is not on or near the manifold andor throttle body. The IAT sensor has two wires coming out of it. Its not covered under powertrain.

Choose an option 18 NPT ¼ NPT ¼-28 O-Ring Seal 38 NPT. Find the BLACK sensor ground wire and the REDBLUE intake air temperature sensor wire going into the back of the MAF plug and cut them. This means that the IAT sensor is reporting a temperature of -38 F -39 C.

The wire should show approximately 0 ohms of resistance. If one of the wires show infinite resistance that wire is broken. Some TPI engines use a sensor with a brass housing and visible thermistor top right.

Threads are 38 NPT. Air Temperature Sensors quantity. These should be installed in your intercooler piping right before the throttle body to minimize heat soak on the sensorInstructions for wiring the sensor on a MKIV Supra can be found by clicking here.

This process is basically the same for any automotive connector. If you still find no problems the fault may be with the computer driver. Other TPI engines use a sensor with a steel housing and sealed thermistor bottom left.

Since you wired in the GM IAT into. Air Temp Sensor with 38 NPT Male Thread High Performance GM-Style Connector Aluminum Bung Connector Pins. Use the following 3 point curve calibration data when using GM IAT Sensor with open element and your MS system.

The threads are 38 NPT pipe thread note that isnt an actual 38 outer diameter but a pipe thread size based on pipe inner diameter. With the wiring harness disconnected from the sensor and computer measure each wire resistance with your ohmmeter. GM open-element intake air temp sensor wiring pigtail.

You can poke wires into the AFM connector or you can cut and splice. Intake Air Temperature IAT Sensor Circuit High Voltage. The LS1 IAT sensor top left requires a grommet or rubber intake tubing for installation.

If your IAT intake air temperature sensor doesnt respond you can. The other wire should be connected to the ECUs sensor ground. Choose an option Hi-AT Sensors -10 to 485F Lo-AT Sensors -30 to 335F Clear.

Use iWires plug and play Speed Density harness that converts the stock connector to the new Intake Air Temperature Sensor connector. In this episode I go over how to convert from the factory 5-wire combination Mass Airflow MAFIntake Air Temperature IAT sensor to a stand alone 2-wire I. This episode is a quick guide for the IAT sensor Intake Air Temperature wiring.

Wire one lead of the GM Sensor to the Brown Wire at the AFM Connector and the other lead of the GM Sensor to the Yellow wire at the AFM Connector. The mass air flow MAF sensor is integrated with the inlet air temperature IAT sensor. Our standard adapter length is 36 inches which works with most common applications.

The MAF sensor is an air flow meter that measures the amount of air entering the engine. Product description Sensor These are the recommended intake air temp sensors for the AEM EMS. Black smoke coming out of the tailpipe.

30-2010 - Air Temp Sensor Kit. After checking it they claim a bad connector or wiring that plugs into the engine MAF sensor. There are two points on the MSPNP where you can connect an IAT sensor.

Choose an option Direct Wire GM Connector M5 Connector. Some GM vehicles use an IAT with a wide flange and foam seal top middle. You will need an IAT sensor and a connector.

That would be pin 92 black on a 2G ECU harness or pin 24 green wblack stripe on a 1G ECU harness or pin 72 black on an EVO1-3 ECU harness. Air Temperature Sensor Type. -40C to 135C -40F to 275F.

If racing class rules do not permit you to remove or even unplug the mass air flow sensor you may wire the IAT to pins 10 and 15 on the 15-pin option connector on the v12 board and pins 20 and 22 on 26-pin option connector on the v13 board. Intake Air Temperature IAT Sensor Circuit Low Voltage. If it is zero your wiring is still shorted.

This means that the IAT sensor is reporting a temperature of 300 F 149 C. Aug 11 This is a write up on how to wire in a GM IAT intake air temp sensor in a 2g and logging it using dsmlink V3. Use this sensor to input Intake Air Temperature IAT to your AEM ECU.

Either wire can be connected to the ECUs IAT input. GM IAT Sensor with open element are proper GM-style sensors for use with ALL MegaSquirt MS3Pro ECUs and include a 6 wire pig-tail with weatherproof connector. GM Open Element IAT Sensor with Pigtail Recommended Fast-Response Intake Air Temp Sensor IAT for use on forced induction vehicles.

These are the proper GM-style sensors for use with the MegaSquirt line of ECUs and include a 6 wire pig-tail with weatherproof connector.
