Product Details

The Walker 225-1054 MAP sensor is used by the engine control system to read manifold pressure and help the ECU calculate fuel delivery and ignition strategy. Walker Products has supplied fuel system and engine sensor components since 1946, and its product development is backed by in-house manufacturing, engineering, and technical support. This part cross-references Standard Ignition AS312 for the same application.

• Erratic idle caused by inaccurate manifold pressure input
• Hard starting related to incorrect load sensing
• Reduced throttle response from a faulty MAP signal
• Check engine light triggered by MAP sensor circuit faults
• Fuel trim concerns caused by inconsistent intake pressure readings

Installation Notes and Tips

Verify connector style, terminal count, and mounting location before installation. Confirm the vehicle application against the listed fitment for 2004-2008 Chevrolet Aveo, 2007-2008 Chevrolet Aveo5, and 2014 Chevrolet Aveo.
