As far as I am aware there is not a calibration for the temperature aspect. The compass can be calibrated, but the temperature is set by the sensor and non "offset"able.
does anyone know where the sensor is for the temperature part of the compass temp unit in a 2000 f150? I resoldered yje 510 resistors and the unit lights up just fine now.
temp probe is up in front of the radiator, behind the grill, somewhere by the hood latch. Should be a small plastic probe with 2 wire harness back to the console.
each year and model are a little different, you need to look at the operators manual for that year. basically you take a tooth pick and push in the small hole on the bottom -- several times untill it reads the right VAR.. that is the location on the map. I know Illinois and iowa are something like 8-9. Using the right number will make a more exact compass since NORTH is not exactly at the axis of rotation. After you get the right VAR, you push the button again and then drive in a 50 ft diameter circle about 3 times untill the compass kicks out of cal and reads the correct value.. Look up the operators manual and verify.
I think I am having problems with the sensor... To be more precise, I am not sure if the sensor is bad or if I have a short in the wiring. Whats is the best way to approach this? What reading should i have across the sensor wiring harness?
I believe the sensor should have 8000-14000 ohms. remove connector check resistance across sensor. mine had 300,000 ohms (BAD) THE BOARD HAD TO BE LOOKED AT AS WELL. i SOLDERED THE 510 OHM RESISTORS(THEY ARE FLAT AND ON THE BOARD BUT START TO LIFT UP AWAY FROM THE BOARD) DID BOTH OF THEM. WORKS FINE NOW AND i REPLACED THE SENSOR(42) BUCKS READS RIGHT NOW. SIMPLE TO FIX THIS. LET ME KNOW HOW IT GOES
I have a 2000 F250, the temp in the overhead display is consistently off by 30 degrees. I replaced the sensor on the core support to the left of the radiator. Same result. I believe that sensor to be ambient air temp for the fuel injection. Is there another one for the overhead display?
