Detailed Product Description

The Standard Ignition AS512 fuel tank pressure sensor monitors pressure changes in the evaporative emissions system so the engine control module can evaluate tank and vapor system behavior. This sensor is a direct-fit style OE replacement for a range of Honda and Acura applications, including Honda Accord, Honda Odyssey, Honda Insight, Honda S2000, Honda Pilot, Acura CL, Acura TL, and Acura MDX. If you are replacing a failed sensor on a 1998-2005 Honda Accord or a 2001-2004 Acura MDX, AS512 provides the correct connector and terminal configuration for service work.

Common Problems This Part Can Address

• Evaporative emissions fault codes related to fuel tank pressure readings
• Check engine light concerns tied to the EVAP system
• Incorrect tank pressure signal output to the engine control module
• Inspection or emissions test failures caused by pressure sensor faults
• Driveability issues linked to inaccurate evaporative system monitoring

Installation Notes and Tips

Verify connector shape, terminal count, and vacuum port layout before installation. This sensor uses a female plug-in connector with 3 male blade terminals and does not include mounting hardware, O-rings, or a wiring harness. Confirm the vehicle application by year, make, and model before replacing the original unit.

Quality Assurance

Standard Ignition AS512 is an OE replacement part built to match the original sensor style used in the listed Honda and Acura applications. It is suitable for service on vehicles that require the specified fuel tank pressure sensor configuration.
