2001 Ford Explorer Sport Active Suspension Relay Replacement Guide
If your Explorer Sport's air suspension is acting up, the relay is a common and easy part to replace.
- A bad relay is a very common cause for air suspension problems on the 2001 Explorer Sport.
- Symptoms include a sagging rear end or an air compressor that won't turn on or won't turn off.
- Before replacing, check the two air suspension fuses (20A and 40A) in the under-hood fuse box.
- Replacement is extremely easy for a DIYer and involves swapping the relay in the engine bay fuse box.
Is Your Explorer Sport Suspension Sagging or Stuck?
A failing active suspension relay is a common problem on the 2001 Ford Explorer Sport. Because this relay controls the power to the air compressor, its failure can cause a few distinct and frustrating symptoms. Understanding these signs can help you pinpoint the relay as the culprit before it causes more expensive problems.
Symptoms of a Bad Active Suspension Relay
- Suspension Stuck Down: The most common symptom. If the relay fails to activate, it won't send power to the compressor. This means the air springs can't inflate, causing the rear of the vehicle to sag and ride on the bump stops. This results in a harsh, bouncy ride.
- Compressor Won't Turn On: You may notice the familiar sound of the air compressor kicking on is absent. Even if the rest of the system is working, a dead relay means a dead compressor.
- Compressor Runs Constantly: Less common, but a relay can fail in the 'on' position. This will cause the compressor to run continuously, even when the vehicle is off. This can burn out the compressor motor, leading to a much more expensive repair.
- "Check Suspension" Light: Your dashboard may display a warning light, as the vehicle's main computer detects a fault in the suspension system's operation.
Don't Ignore a Bad Relay
A relay that is stuck on can destroy your air suspension compressor. A relay that is stuck off can lead to a very poor ride quality and potentially damage other suspension components from the constant bottoming-out. For a low-cost part, it's best to replace it at the first sign of trouble.
Choosing the Right Aftermarket Relay
For a vehicle like the 2001 Explorer Sport, finding an original equipment (OEM) relay from Ford can be difficult and expensive. Luckily, aftermarket electronics have come a long way. A single, high-quality aftermarket brand is often a more practical and equally reliable choice.
Brand Tiers: Standard Ignition
The primary aftermarket brand available for this specific relay is Standard Ignition (Standard Motor Products or SMP). SMP is a well-respected name in the auto repair industry. They have been manufacturing quality electrical components for decades and are often considered an OEM-equivalent or even superior in some cases. For a simple part like a relay, their reputation for quality control and durable materials makes them a trusted choice. You can be confident that a Standard Ignition relay will restore proper function to your air suspension system.
Pro Tip: Check Your Fuses First
Before replacing the relay, always check the related fuses in the power distribution box under the hood. A simple blown fuse can mimic the symptoms of a failed relay. The 2001 Explorer has two fuses for the air suspension system, a 40A and a 20A, in slots 9 and 8 respectively.

Frequently Asked Questions
Where is the active suspension relay located on a 2001 Ford Explorer Sport?
The active suspension relay is typically located in the power distribution box in the engine compartment, near the battery. It is a small, cube-shaped component that can be unplugged and replaced without any special tools.
Can a bad relay damage my air compressor?
Yes. If the relay gets stuck in the 'on' position, it will force the compressor to run nonstop. The compressor is not designed for continuous use and will overheat and burn out, turning a simple relay replacement into a much larger and more expensive job.
Is this a difficult part to replace myself?
No, this is one of the easiest repairs you can do. It involves locating the correct relay in the fuse box, pulling the old one straight out, and pushing the new one in. It requires no tools and takes less than 5 minutes.
Is the active suspension relay the same as the load-leveling relay?
Yes, for the 2001 Ford Explorer Sport, these terms are often used interchangeably to describe the same part that controls the air suspension compressor.
