Hi everyone, I am about to do manual oil pressure check. Where would be the best spot to hook up the oil pressure Guage on 2012 Maxxforce 13.
Find the oil sensor on the engine, remove it and tap in there. Will tell you how accurate your gauge is, where if you tap in somewhere else it may be out a couple pounds one way or another from the oil sensor hole.
Easiest way is to remove oil pressure sensor and install the test fitting. Oil Pressure Test Fitting tool number is, 12-889-02.
@Heavyd If I remove the oil pressure sensor to Put a manual gauge on, how can I stop the truck from shutting off due to no pressure?
I was actually trying to google one but I’m not entirely sure of the size of fittings and stuff needed 2016 n13 645k miles Deleted (not sure if a tune could be throwing the ecm off) for context my truck has an issue with oil pressure under load and high temperature I’ve replaced my entire oil cooler module with the crank case breather oil cooler etc My pressures by gauge are as follows before module Cold Start idle 40 psi Cold rev 48-50 psi Bobtailing 1500rpm 40 psi Heat soaked 1500 rpm 28-40 psi Hot idle 8-15 psi after module Cold start idle 40 psi Cold rev 60-70 psi all Other pressures are the same as before the module change the truck doesn’t knock (I may have heard a knock one time before it shut off but it could be my paranoia) or do anything else abnormal it logs code spn 100 fmi 18 religiously over 50 counts last time I checked the codes via dashboard other things I’ve done Checked the voltage the sensor was putting our by back probing the wires this was in tune with what the ecm is seeing other random things that may be related the truck is pretty wacky with all of the gauges that I believe are ran through the canbus/ecu fuel gauge jumps around Speedo jumps around Coolant temperature never goes above 140 degrees unless I’m in a hill pull with weight Jpro matches all figures the cluster is showing me (I’ve changed out coolant sensor for a new one and jumped the two pins together which pegged the coolant gauge to hot) voltage gauge Air pressure gauges Rpm are all accurate and stable so with all that being said it’s strange that the oil cooler module would only have an effect on cold start revving. also I can recreate any of the pressures I listed above which tells me it’s pretty consistent
