Power Steering Pressure (PSP) Switch

DESCRIPTION
The Mass Air Flow (MAF) Sensor directly measures the mass of the air flowing into the engine. The sensor output is a DC (analog) signal ranging from about 0.5 volt to 5.0 volts used by the Powertrain Control Module (PCM) to calculate the injector pulse width for stoichiometry. For transaxle strategies, the MAF sensor input is used for electronic pressure control (EPC) control, shift and torque converter clutch (TCC) control.

SYMPTOMS
High/low EPC pressure, incorrect shift schedule, incorrect torque converter engagement scheduling and symptoms similar to a throttle position sensor malfunction.
