Mass Air Flow (MAF) Sensor

DESCRIPTION
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 PCM to calculate the injector pulse width for stoichiometry. The PCM also uses this signal for EPC pressure control, shift and torque converter clutch scheduling.

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

DIAGNOSTIC TROUBLE CODES
P0102, P0103, P1100, P1101
