Walker 245-1433 is built as an OE-style replacement for service work where the original housing and connector style matter. It is a relevant choice for technicians and owners searching for a Walker mass air flow sensor, Walker 245-1433, or a replacement mass air flow assembly for Honda Civic and Toyota Corolla applications.

Common Issues It Can Help Address

• Rough idle caused by inaccurate airflow readings
• Hesitation during acceleration
• Check engine light related to air metering faults
• Poor fuel trim behavior from a failing MAF sensor
• Driveability complaints tied to contaminated or worn sensor elements

Installation Notes

Verify connector style, terminal count, and housing configuration before installation. This unit uses a female connector and 5 terminals, and mounting hardware is not included. Clean the intake tract and inspect the air filter housing before installing the new assembly to help prevent contamination of the sensor element. Confirm vehicle-specific calibration and application details for the exact make and model before ordering.
