Warm up the engine to operating temperature Disconnect the connector of the control pressure regulator and connect a voltmeter to the regulator block. Turn on the ignition and determine the supply voltage of the regulator using the voltmeter, which should be at least 11.5 V Connect an ohmmeter to the terminals of the regulator and check the resistance of its thermal winding, which should be within 20-26 Ohms. If the ohmmeter shows infinity, this indicates a break in the thermal winding and the control pressure regulator must be replaced.
