Gm Iat Sensor Wiring

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.

Gm iat sensor wiring. Black smoke coming out of the tailpipe. 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. 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.

This means that the IAT sensor is reporting a temperature of -38 F -39 C. With the wiring harness disconnected from the sensor and computer measure each wire resistance with your ohmmeter. Its not covered under powertrain.

Genuine Delphi GM Original Equipment Manufacturer - OEM 2 wire Metri-Pack 1502 connector replacement pigtail for many GM Intake Air Temperature IAT Sensors. Commonly used with many 1979-newer GM vehicles. Choose an option Direct Wire GM Connector M5 Connector.

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. Some GM vehicles use an IAT with a wide flange and foam seal top middle. 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.

If you still find no problems the fault may be with the computer driver. Intake Air Temperature IAT Sensor Circuit High Voltage. GM open-element intake air temp sensor wiring pigtail.

Other TPI engines use a sensor with a steel housing and sealed thermistor bottom left. This episode is a quick guide for the IAT sensor Intake Air Temperature wiring. Choose an option Hi-AT Sensors -10 to 485F Lo-AT Sensors -30 to 335F Clear.
