ImportTuning Posted December 4, 2019 Report Share Posted December 4, 2019 Hello, i need to wire my engine oil temperature sensor (bosch 0280130026) to Temp 4, so i need 1k ohm resistor, where i put that resistor which wires to where and resistor where...? Draw me a picture or tell me how to do that instructions for dummies style Help Rookie to put that sensor working...my Temp 1 and 2 are used where is internal resistor so this is why i have to use that external... Thanks Quote Link to comment Share on other sites More sharing options...
Simon Posted December 4, 2019 Report Share Posted December 4, 2019 All the temp channels have an internal pullup ready to go, Temp 1 and 2 it is switchable but on 3 and 4 it is fixed. No need for and external pullup on temp 3/4 Quote Link to comment Share on other sites More sharing options...
ImportTuning Posted December 5, 2019 Author Report Share Posted December 5, 2019 Ok that is good to know! but i dont understand why this sensor doesnt show me real temperature only -50c what is not possible what i´m doing wrong? 2-pin bosch sensor first pin to Temp 4 and second spliced to sensor ground...is this ok? I try to gonfigure that i put sensor type to STD Bosch it is -50c no change and then make my own calibration to cal 3 table still it is -50c...

Yes, this is correct. Is the error low set to 0.05 & the error high to 4.95? Quote Link to comment Share on other sites More sharing options...

Adamw Posted December 5, 2019 Report Share Posted December 5, 2019 Ok, for now set the error low to 0.0 and error high to 5.00, this will disable the error overrides so they dont confuse our diagnosis. If temp still shows something low like -40°C with these error settings turned off then that means either there is no connection to the sensor or it is open circuit. If it shows high temperature then it means the sensor is a dead short to ground. Quote Link to comment Share on other sites More sharing options...
