Claim Text:
1. A method for determining off-temperature behavior of a solenoid fluid control valve, the method comprising: performing a current sweep that comprises running a current through a coil of the solenoid fluid control valve and measuring a control pressure as a function of the current, wherein the current sweep is performed at a first temperature; choosing a first and second characterization control pressure for characterizing the solenoid fluid control valve; determining a first current corresponding to the first characterization control pressure based on the current sweep; assigning a first metric to the solenoid fluid control valve based on the first current; determining a second current corresponding to the second characterization control pressure based on the current sweep; assigning a second metric to the solenoid fluid control valve based on the second current; and determining information regarding a behavior of the solenoid fluid control valve at a second temperature based on the first and second metrics.
