Detailed Product Description

The Standard Ignition AS143 Fuel Tank Pressure Sensor is engineered to provide accurate pressure readings from the fuel tank of Mazda Protege vehicles. By detecting changes in pressure, this sensor helps the engine control unit (ECU) regulate fuel vapor flow and maintain the evaporative emissions system. Proper sensor function is essential for maintaining fuel efficiency and meeting emissions standards. The AS143 sensor is manufactured to meet OEM specifications, ensuring compatibility and durability in the fuel and air delivery system.

Common Applications and Problem Resolution

This fuel tank pressure sensor is used to address several issues related to fuel system performance and emissions control in Mazda Protege models. It can help resolve:

  • Check engine light triggered by evaporative emissions faults
  • Fuel odor caused by vapor leaks
  • Failed emissions tests due to faulty pressure readings
  • Rough engine idle or stalling related to fuel system errors
  • Decreased fuel efficiency from improper vapor management

Installation Notes and Tips

When installing the Standard Ignition AS143 sensor, ensure the vehicle is turned off and cooled down. Locate the existing fuel tank pressure sensor on the Mazda Protege’s fuel system and carefully disconnect the electrical connector. Remove the old sensor and replace it with the AS143, making sure it is securely seated and connected. It is recommended to inspect the wiring harness and connectors for damage during installation. After replacement, clear any diagnostic trouble codes and verify proper sensor operation with a scan tool.
