SPN 5418 FMI 3 resistance test steps
The procedure disconnects the quantity control valve harness connector and zeroes the DVOM before measuring. Resistance across pins 1 and 2 below 1.3 Ω means the valve is replaced using the Removal of the Quantity Control Valve — Three-Filter System procedure in Power Service Literature. A reading between 1.3 Ω and 1.4 Ω sends you to inspect the 120-pin MCM2.1 connector for corroded or bent pins, then measure pin 1 to ground; more than 10K Ω condemns the valve, less means repairing the short to ground. Engine reaction is a 25% derate with MIL and CEL lit.
