Thread: Transmission Temperature ECU Input

  1. #161

    Default

    Trying to setup an OE GM 2-wire temp sensor that is already in place on the transmission (also same OE sensor on the differential). I have it configured as a GM LSx CTS, which clearly is not correct, as it reads 60F too high compared to ambient temps. I can setup as a 'Custom Therm', but can't find any settings that correlate to the GM 2-wire. (Note: OE transmission temp sensor on a '01 ZO6 T56 transmission & differential.) Any guidance?

    You'll need to ascertain the sensor calibration data (or measure hot & cold temps with an Ohmmeter), or use sensors with known calibration data.

    I've searched, but no such luck. A Holley CTS temp top range is too low at 275F (hopefully never gets that hot, but possible on track). Sounds like an Auto Meter 2259 sensor and connect the single pinned wire would be the best way to go. Thanks!

    You're welcome. There's three different temperature sensors to choose from (LINK).

    I ordered this sensor so I can datalog oil temperatures on my Terminator X. How do people suggest providing the 5V power source? Would a fused switched +12V source work, or do I need to look into a 12V --> 5V adapter? Any recommendations? Thanks.

    The 5V temperature sensor's 5V & Ground wires don't consume any I/O, only the Pin Mapped signal wire does.
    Your EFI main harness most likely has the Power Tap auxiliary 4-wire connector as shown in the center of this diagram.
    See "Wiring Harness Diagram", page 13: https://documents.holley.com/199r11957.pdf (Terminator X '79-'93 Ford Mustang Main Harness Instructions)
    If so, the Power Tap connector provides an easy to tap sensor 5V (pin C - orange) & Ground (pin B - black/white) off it, then connect the signal wire to the (Pin Mapped) HEFI ECU Input.
    If not, the red 5V power supply taps into any sensor 5V power supply on the EFI main harness (or the Power Tap connector's 5V terminal, if your main harness has this).
    If not, the Green Ground wire taps into a Sensor Ground Out wire on the EFI main harness (or the Power Tap connector's ground terminal, if your main harness has this).
    Autosport Labs 3-5 VOLT type linear temperature sensor three wire color codes: Green - Ground, Red - 3-5V, Yellow - Signal Output (Pin Mapped to HEFI Input).
