Fuel Tank Pressure Sensor for Nissan Applications

Standard Ignition AS200 is an OE replacement fuel tank pressure sensor for select Nissan vehicles. It is built with a black external housing, a rectangular plug-in connector, and a 3-blade male terminal layout for direct sensor replacement on the evaporative emissions system.

Compatible With 1998-2002 Nissan Frontier, 1999-2002 Nissan Quest, 2000-2002 Nissan Xterra, and 1999 Nissan Maxima. This Standard Ignition AS200 fuel tank pressure sensor is also listed for 1998 Nissan Quest with California emissions.

Key Features

• OE replacement fuel tank pressure sensor
• External mounting location
• Black finish
• Rectangular plug-in connector with female connector housing
• 3 blade male terminals
• Mounting bracket included
• Sensor only replacement

Detailed Description

The AS200 monitors fuel tank pressure as part of the evaporative emissions system, helping the vehicle control module evaluate tank and vapor system conditions. Standard Ignition AS200 is an OE-style replacement built for select Nissan Frontier, Nissan Quest, Nissan Xterra, and Nissan Maxima applications where the original sensor uses an external mount and a single rectangular connector.

This part cross-references Dayco 72726 for the same application. Standard Ignition AS200 is also referenced by aftermarket numbers including 2-27078 and 5S2493.

What It Is Used For

• Replacing a failed fuel tank pressure sensor
• Restoring evaporative emissions system pressure readings
• Addressing EVAP-related diagnostic trouble codes
• Correcting inaccurate tank pressure signal output
• Resolving drivability issues tied to emissions monitoring faults

Installation Notes and Tips

Install the sensor at the external mounting location and verify the connector, terminal style, and bracket alignment before final assembly. Because this is a sensor-only replacement, reuse the vehicle’s existing wiring harness and related mounting hardware as needed. Confirm exact vehicle application by year, model, and emissions configuration before ordering, especially for the 1998 Nissan Quest California emissions application.

Quality Assurance

Standard Ignition supplies OE replacement electrical and emissions components for service applications. AS200 is built to match the original sensor style and connection layout used on the listed Nissan Frontier, Quest, Xterra, and Maxima vehicles.
