Service
The AC4019, AC87, 237810F300, 237810F310, and 237810F320 are idle air control valves built for the Nissan D21 Pickup and later Nissan Pickup models with the 2.4L L4 engine, covering 1990 through 2004. This IAC valve handles the bypass air that goes around the throttle plate when your foot is off the gas.
We do not treat quality as a final step. It runs through every stage of production. Each idle air control valve is flow-calibrated on a bench to ensure the bypass air matches the original equipment curve. We also cycle-test these IAC valves at both high and low temperatures to confirm they hold up in real-world conditions—from cold winter starts to hot summer traffic.
Our facility follows documented procedures that meet strict industry standards. We keep records on every batch, so you have traceability behind every unit.
Q1: How long does this IAC valve typically last compared to the original Nissan part?
Our valve is built with high-quality components and undergoes rigorous quality control, so its lifespan is designed to match or exceed the original OEM part under normal driving conditions.
Q2: Will a faulty IAC valve trigger the check engine light on my Nissan?
Yes, a failing idle air control valve often causes unstable idle speed or stalling, which can trigger the check engine light and store a diagnostic trouble code (e.g., P0505) in your vehicle's computer.
Q3: Can I install this IAC valve myself, or do I need a professional mechanic?
While this valve is a direct OEM fit with bolt-on installation, we recommend professional installation if you're not experienced with throttle body or engine management components to ensure proper sealing and calibration.
Q4: What happens if the valve doesn't solve my idle problem after installation?
If you encounter any issues, our technical support team provides free consultation to help diagnose the problem, and we stand behind our product with a quality assurance policy that includes replacement options.
Q5: Does this valve come with a warranty, and what does it cover?
Yes, this IAC valve comes with a standard warranty against manufacturing defects. Please contact us with your order details for specific warranty terms and coverage duration.
