You’re blasting down your favorite trail, the engine is humming, and life is good. Then, it happens. The dreaded check engine light flicks on, your dash flashes a code, and your powerful Polaris General suddenly feels like it’s lost its punch. You look down and see polaris general fault code 746. Your heart sinks a little. A great ride just hit a major speed bump.
We’ve all been there. A mysterious code can turn a day of fun into a day of frustration. You start wondering if it’s a simple fix or a trip-ending, wallet-draining disaster.
I promise you, this guide will demystify that code. We’re going to break down exactly what it means, show you the common causes, and walk you through a step-by-step diagnostic process you can do right in your garage. By the end of this article, you’ll have the confidence and knowledge to track down the problem and get your General back to full power.
Let’s grab some tools and get that machine running right.
What Exactly is Polaris General Fault Code 746?
First things first, let’s get to the bottom of this code. Seeing polaris general fault code 746 points directly to an issue with the Turbocharger Wastegate Solenoid Circuit. In plain English, it means the computer (ECU) in your General has detected an electrical problem with the component that controls your turbo’s boost.
The wastegate solenoid is a small but critical valve. Its job is to manage the exhaust gas that spins the turbo. By opening and closing, it precisely controls how much boost the turbo produces. When it’s not working correctly, your engine can’t make the power it’s supposed to.
You’ll often see this code accompanied by a sub-code, which gives you a huge clue:
- 746 3: Voltage Above Normal / Short to B+ (Battery Positive). The ECU is seeing too much voltage in the circuit.
- 746 4: Voltage Below Normal / Short or Open to Ground. The ECU isn’t seeing enough voltage, or the circuit is broken.
When this fault occurs, your General’s ECU will likely put the machine into “limp mode” to protect the engine from potential damage. This results in that sluggish, low-power feeling you noticed on the trail.
Common Problems Causing Fault Code 746
Before you start ordering expensive parts, take a breath. More often than not, this code is caused by something simple. Off-road machines live a rough life of vibrations, mud, and water, and the wiring is usually the first victim. This is a key part of our polaris general fault code 746 guide.
Wiring and Connector Issues
This is, by far, the most common culprit. The wiring harness leading to the wastegate solenoid is exposed to heat and vibration. Over time, wires can chafe against the frame or engine components, creating a short or a break in the circuit. The connector itself can also get filled with mud or water, causing corrosion and a poor connection.
A Faulty Wastegate Solenoid
While less common than wiring problems, the solenoid itself can fail. The internal coil can burn out, creating an open circuit (leading to code 746 4), or it can short internally. It’s a simple electromagnetic valve, and like any electronic part, it has a finite lifespan.
ECU (Engine Control Unit) Problems
This is the least likely cause, but it’s a possibility. The driver circuit inside the ECU that controls the solenoid could fail. Always rule out wiring and the solenoid itself before even considering the ECU is the problem. This is a last resort diagnosis.
Tools and Gear You’ll Need for the Job
You don’t need a full professional shop to tackle this, but having the right tools makes all the difference. Here’s a basic list to get you started on how to polaris general fault code 746 diagnostics.
- Basic Hand Tools: A good socket set, wrenches, and screwdrivers.
- Digital Multimeter: This is non-negotiable. You cannot properly diagnose this code without one. Even an inexpensive one will work.
- Electrical Contact Cleaner: A must-have for cleaning dirty connectors.
- Dielectric Grease: To protect your electrical connections from moisture and corrosion after cleaning.
- Inspection Light or Headlamp: Good lighting is key to spotting damaged wires.
- Zip Ties and Electrical Tape: For securing repaired wires and keeping your harness tidy.
- Safety Gear: Always wear gloves and safety glasses.
Your Step-by-Step Polaris General Fault Code 746 Guide
Alright, let’s get our hands dirty. Follow these steps in order. Do not skip a step, as the goal is to find the simplest problem first. This is one of the most important polaris general fault code 746 tips we can offer.
Step 1: Locate and Visually Inspect
First, find the turbo wastegate solenoid. On most Polaris General models, it’s mounted near the turbocharger. It will have a two-wire electrical connector and two small vacuum/boost hoses attached to it. With your light, meticulously inspect the entire length of the wiring harness leading to that connector. Look for any signs of rubbing, melting, or pinching. Wiggle the harness gently to see if any wires are brittle or broken inside their insulation.
Step 2: Check the Connector
Disconnect the electrical connector from the solenoid. Look inside both ends. Do you see any green or white crusty corrosion? Are any of the pins bent or pushed back? Even if it looks clean, spray both the solenoid side and the harness side with electrical contact cleaner. Let it dry completely, then apply a small dab of dielectric grease to the seal before reconnecting it firmly. Sometimes, this is all it takes.
Step 3: Test the Solenoid’s Resistance
Here’s where your multimeter becomes your best friend. Set it to measure Ohms (Ω). With the connector unplugged, touch one probe to each of the two metal pins on the solenoid itself. You are measuring the resistance of the internal coil. A good solenoid should typically read between 10 and 20 Ohms. If you get an “OL” (Open Loop/Infinite resistance) reading, the coil is broken, and the solenoid is bad. If you get a very low reading (near 0 Ohms), it’s shorted, and the solenoid is bad.
Step 4: Check for Voltage at the Harness
This step checks if the solenoid is getting power from the ECU. Turn your multimeter to DC Volts. Turn the vehicle’s key to the “ON” position (do not start the engine). Carefully probe the two terminals in the harness-side connector. One wire should have battery voltage (around 12V), and the other is the ground controlled by the ECU. If you don’t see any voltage, you have a broken wire or blown fuse somewhere between the ECU and the connector, confirming a wiring issue.
Step 5: Clear the Code and Test Ride
If you’ve found and fixed an issue (like a corroded connector or a broken wire), it’s time to see if your work paid off. After your repair, start the engine. Sometimes the code will clear on its own after a few key cycles. Take it for a gentle test ride. If the power is back and the check engine light stays off, you’ve successfully solved the problem!
When to Put Down the Wrenches and Call a Pro
There’s no shame in knowing your limits. DIY is great, but sometimes a problem needs a professional touch. Here are some clear signs it’s time to call your trusted mechanic or dealer:
- You’re not comfortable using a multimeter or working with vehicle electronics.
- All your tests pass—the wiring looks good, the solenoid has correct resistance, and the harness has voltage—but the code persists. This could point to a complex intermittent issue or a rare ECU failure.
- You find a majorly damaged wiring harness that requires more than a simple patch job.
- You simply don’t have the time or tools to do the job safely and correctly.
Preventative Care and Sustainable Riding: A FatBoysOffroad Approach
Fixing a problem is good, but preventing it is better. Adopting a few polaris general fault code 746 best practices can save you headaches down the road. This is the core of a sustainable polaris general fault code 746 prevention plan—making your machine more reliable and reducing trail-side failures.
Think of it as an eco-friendly approach to off-roading; a well-maintained machine is less likely to break down, leak fluids on the trail, or require wasteful replacement parts. Your polaris general fault code 746 care guide is simple: during your regular post-ride wash and check-up, take 5 extra minutes to visually inspect key wiring harnesses, especially around the hot, vibrating engine. Ensure they are properly secured and not rubbing on anything. A strategically placed zip tie can prevent a wire from chafing through and ruining your next trip.
Frequently Asked Questions About Polaris General Fault Code 746
Can I still drive my General with code 746 active?
You can, but it’s not recommended for long. The machine will be in a power-reduced “limp mode” to protect the engine. It’s designed to get you slowly and safely back to the truck or camp, not to continue your ride.
How much does it cost to fix fault code 746?
The cost varies wildly depending on the cause. If it’s a loose or dirty connection you fix yourself, it could cost you nothing but time. A new wastegate solenoid might cost between $50 and $150. If it requires a professional diagnosis and wiring repair, you could be looking at a few hundred dollars in labor.
Where is the turbo wastegate solenoid located on a Polaris General?
It is almost always mounted directly on or very close to the turbocharger assembly. It’s a small, typically black plastic component with a two-wire electrical plug and two small hose ports. Follow the small vacuum/boost lines from the turbo wastegate actuator, and they will lead you right to it.
Tackling an electrical fault code can seem intimidating, but as you can see, the polaris general fault code 746 is often a straightforward fix. By following a logical process, you can isolate the problem without just throwing parts at it. You have the knowledge and the steps to diagnose this issue like a pro.
So, get out there, check those wires, and get your General’s power back. Stay safe, stay muddy, and we’ll see you on the trails!
