Seeing the SPN 2011 FMI 9 fault code? It signals a communication loss with your ABS module. This guide walks you through the most common causes, like bad wiring or power loss, and provides a simple step-by-step process to diagnose and fix the problem.
Whenever you run into an electrical problem, the fuse box is the first place to look. In this guide, we’ll dive into the Ford fuse box diagram with the example of a Ford F150 to help you better know the fuses in your Ford trucks.
Inner and outer tie rod: which one is worn out? The outer tie rod usually goes first—it’s exposed to mud, water, and rocks. The inner end sits tucked under a rubber boot, so it lasts longer. This guide helps you figure out which one is causing your steering trouble without guessing and changing the wrong part. Learn the 3-and-9 o’clock test to check for play, how to inspect both joints, and which symptoms point to each failure—clunking over bumps usually means outer, while vague steering or shimmy at speed points to inner. Replace both sides together, count the turns, and always get a wheel alignment after the job.
If your machine’s battery keeps dying, a parasitic draw is the likely culprit. This guide explains the signs and shows you how to test for parasitic draw with a multimeter. Follow our simple steps to find the faulty circuit yourself.
This guide details common transmission speed sensor symptoms like rough shifting, power loss, and incorrect speedometer readings. A faulty sensor sends bad data, leading to poor performance and potential transmission damage. Learn what causes failure and why a quick fix is crucial.
Here are 11 common engine knocking causes:
Low-octane or poor fuel quality: Octane is a measurement that tells you how resistant a fuel is to abnormal combustion. If you use a lower octane than recommended by your vehicle owner’s manual, the fuel can pre-ignite and cause engine knock.
Low motor oil levels or poor oil quality: Insufficient or degraded engine oil can increase friction and heat inside the engine. Higher operating temperatures can contribute to abnormal combustion and increase the possibility of knocking.
Excessive carbon buildup: Gasoline contains carbon, which can leave deposits and buildup on critical engine components like the combustion chamber surfaces. Over time, carbon deposits accumulate on pistons and valves, reducing space inside the combustion chamber and raising pressure and heat. Then, pre-ignition and knocking become likely
Uneven cuts and shaking are signs your deck needs help. This John Deere mower deck repair guide shows you how to fix cracked spindle mounts, replace worn pulleys and belts, and sharpen blades for a better cut and longer equipment life.
SPN 636 FMI2 signals a fault in the crankshaft position sensor circuit. The FMI2 suggests that the electronic control module (ECM) has detected an abnormal signal from the sensor, which could lead to poor engine performance, misfires, or difficulty starting the engine. In this guide, we’ll dive into the symptoms, causes and easy fixes of the error code.
Bad ignition switch symptoms: how to tell if it’s failing? No crank?No crank? Starts then stalls? The catch is, a weak battery, a starter on its last leg, or a wiring glitch can pull off the same act. This guide takes you through the usual warning signs—no crank, starts and stalls, dash power cutting in and out, a key that doesn’t turn smoothly, or power suddenly returning when you move the key—and helps you sort out whether it’s the switch, the battery, or the starter. We’ll also walk through what to check before you replace anything: battery voltage, terminal connections, ground straps, fuses, and the connector for heat damage or corrosion. Look at the whole pattern—one symptom alone doesn’t tell the whole story.
This guide explains how to read V-belt numbers to ensure you buy the correct replacement. We cover standard, wedge, and metric belt codes, what the ‘X’ suffix means, and how to measure a belt if the number is worn off.
When summer is in full swing, nobody wants to climb into the driver’s seat and drive around sweating like a pig. Picture being on a long trip in a heavy-duty truck or a car to another place and your A/C suddenly blowing warm air, with the temperature quickly reaching 150 degrees. That’s freaking daunting, right? In this guide, we’ll walk you through why your car AC blowing hot air and how you can troubleshoot the unit and fix it yourself before taking it to your local mechanic.
There are many oil seals and gaskets in an engine to lock lubricant inside to grease and cool various parts. The camshaft seal is one of the most critical engine parts. While made from tough materials, the cam seal can wear out over time, causing serious oil leaks and costly repairs. In this blog, we’ll walk you through the symptoms, causes and fixes of a camshaft seal leak.
