5-pin LSU 4.9

Post by greekguy »

Hello everyone, that's my first post here.

I'm waiting for my uaefi to arrive and I have bought an LSU 4.9 sensor but I realised that it doesn't have a wire connected on pin 5 (but the pin is present on the connector) which is the calibration resistor. I have measured the resistance between pin 5 and every other pin and have found that there is resistance of 285ohm between pin 5 and pin 1 (red wire). Every wire is connected per instructions on the corresponding pin on the connector except pin 5 (green wire). Can I use this sensor as is, does it need any modifications or is it incompatible?

Thank you in advance!

Please connect six wires to the six pins on the connector. Congrats on locating calibration resistor which is part of the sensor connector!
