lacrosseman 2010. your oil pressure is good for now 25 idle and 75 high idle (after 15 min) at this time i would install t fitting and install new sending unit and hook up your mechanical gauge at same time and strapped it to wiper blade and go for road test , uphill and get it up to temp , and let us know what do you see on that oil pressure gauge and is oil light still on at idle after road test ? dont blow it up just drive normally
Low oil pressure light is controlled by ECU, if the sensor is reading correct per the mechanical gauge then the ECU has turned the light on then its fair to say the ECU thinks the oil pressure has hit the low threshold.
We really need him to read the oil pressure data from the ECU and compare to the mechanical gauge.
What kind of tool is required for that?
TorquePro does not display oil pressure.
I always believed that the oil pressure sensor was nothing more than a switch. Once pressure is achieved, switch closes and light turns off.
The pressure sender itself is analog, the ECU uses a software setpoint to turn on/off the Oil pressure light.
