Product Details

Walker Products has supplied fuel system and engine sensor components since 1946, with a focus on meeting or exceeding OEM standards and specifications. The Walker Products line includes engine management components such as throttle position sensors, cam and crankshaft sensors, oxygen sensors, fuel injectors, and related repair parts. Part number 225-1226 is a MAP sensor application used in select Nissan and INFINITI vehicles, including 2014-2017 INFINITI Q50, 2009-2014 Nissan Maxima, and 2014-2017 Nissan Rogue vapor canister applications. This part cross-references Delphi PS10230 for the same application.

What It Helps Address

• Erratic engine load or pressure signal readings
• Check engine light concerns related to manifold pressure input
• Rough idle or drivability issues tied to sensor output
• Fuel control problems caused by inaccurate pressure data
• Sensor replacement needs on Nissan and INFINITI engine management systems

Installation Notes and Tips

Verify the sensor location before ordering, since fitment varies by vehicle and application notes such as intake manifold, vapor canister, or sensor-only configurations. Confirm the part number 225-1226 against the original sensor and match the vehicle year, make, model, and location exactly. For best results, inspect the connector and mounting area before installation and clear any stored diagnostic codes after replacement.
