Product Details

The APW Warehouse Supplies AP4-138 is a direct-fit replacement oxygen sensor designed to restore proper exhaust gas monitoring and fuel management to your vehicle. Oxygen sensors play a critical role in your engine's closed-loop fuel control system, continuously measuring the oxygen content in exhaust gases and sending real-time voltage signals to the engine control module (ECM) to maintain an optimal air-to-fuel ratio.

A failing oxygen sensor can trigger a check engine light (MIL), reduce fuel economy, increase harmful emissions, and cause poor engine performance. Replacing a worn or defective O2 sensor with the AP4-138 helps restore engine efficiency and ensures compliance with emissions standards.

Key Features:

  • Direct-fit replacement for OEM oxygen sensor
  • Restores accurate exhaust oxygen measurement for proper fuel trim
  • Helps eliminate oxygen sensor-related diagnostic trouble codes (DTCs)
  • Designed to meet or exceed original equipment specifications
  • Supports proper closed-loop engine operation for optimal fuel economy
  • Compatible with standard oxygen sensor wiring harness connectors

The AP4-138 oxygen sensor is an affordable, reliable solution for restoring your vehicle's emissions and fuel management systems to factory performance levels.

Before I buy any auto part I check prices at Autoplicity. Almost always the price is significantly lower than anywhere else: Rock Auto, Summit, Jegs, etc... <br><br>Do yourself a favor and check their prices prior to your next purchase and save yourself some money.
