Mass Air Flow (MAF) Sensor
1998 Mercury Sable V6-3.0L DOHC VIN SSECTION Mass Air Flow (MAF) Sensor
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 to calculate the injector pulse width for stoichiometry. The powertrain control module also uses this signal for electronic pressure control (EPC) 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.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
