Walker Products Mass Air Flow Sensor P/N:245-1269
Walker Products 245-1344 mass air flow sensor for the 2002 Infiniti Q45 V8 4.5L measures incoming air so the ECU can set the air-fuel mix. The Walker Products mass air flow sensor is built as a sensor assembly, with the housing included.
A rough idle, hesitation, weaker fuel economy or a check engine light can go with a failing air flow sensor. Those signs alone do not prove the sensor is at fault, since a leak in the intake air path is another common source.
This mass air flow sensor fits the 2002 Infiniti Q45 V8 4.5L, which takes one. This listing is a single sensor.
