J. Goreham | Last updated Friday, April 28th, 2023

A common issue with cars often involves a faulty crankshaft position sensor. This tiny part keeps an eye on how the engine's crankshaft spins, sending important details to the car's computer. When it's not working right, the engine's efficiency takes a hit.
Now, about a temporary fix for the crankshaft position sensor, there are a few DIY steps you can try. But keep in mind, these fixes might not solve the problem permanently.
It's smart to get a professional mechanic's help to figure it out and ensure the engine runs smoothly again. They'll know exactly what to do to fix or replace the sensor if needed, giving you peace of mind on the road.

Temporary Fixes for a Faulty Crankshaft Position Sensor

Sadly, fixing it permanently means replacing the sensor. But there are short-term solutions I've tried to keep the engine going.
I'll share three methods I've used to tackle this issue and get the car running temporarily. These fixes won't last long-term, but they can help until you can replace the sensor.

Method 1: Cleaning the Sensor

To regain your engine's functionality, start by cleaning the sensor—a crucial method for troubleshooting. Here's a simplified, effective approach:
What You Need:
  • Clean rag
  • Isopropyl alcohol

Step-by-Step Guide:

  • Find the sensor in your car—check your manual if unsure.
  • Disconnect the sensor from wires.
  • Gently wipe off dirt with the cloth, be gentle.
  • Use alcohol on the cloth to clean stubborn dirt.
  • Put the sensor back in place.
  • Start the car. If issues continue, try other fixes.

Method 2: Adjusting the Sensor's Position

Adjusting the sensor's position is a key fix when it's off-kilter. Here's what I did!
Tools You Need:
  • Socket wrench
  • Torque wrench

Step-by-Step Guide:

  • Find the sensor in your engine.
  • Loosen its bolts a bit using the socket wrench - don't take them out.
  • Use the torque wrench to adjust the sensor based on your car's manual.
  • Tighten the bolts well with the torque wrench.
  • Start the car to check if the engine runs better. If not, try other fixes.
Be careful and refer to your car's manual for accurate adjustments.

Method 3: Replacing the Sensor's Wiring

Fixing sensor problems in your car might mean changing the wiring. Here’s a simple guide:
What You Need:
  • New wiring harness for your car's model

Step-by-Step Guide:

  • Find the crankshaft position sensor in your engine.
  • Disconnect it from the wiring by pressing a tab or releasing a clip.
  • Use a wire cutter to separate the sensor from the old wiring.
  • Connect the new wiring to the sensor, matching wire colors.
  • Reattach the sensor to the new wiring.
  • Start your car to check if the engine works better.

Warning Signs of a Failing Crank Sensor

Understanding when your car's crankshaft position sensor isn't working properly can save you from bigger problems down the line. This sensor is like the engine's eyes and ears, keeping track of how the crankshaft moves. But when it starts acting up, your car might show some clear signs.
Here's what to look out for:
  • Engine problems: If your engine stalls or misfires while driving slowly, it could be due to a faulty sensor. It might send wrong signals to the car's computer, making the engine act strange.
  • Hard to start: Difficulty starting your car, especially if it takes longer than usual or won't start at all, could mean the sensor isn't doing its job of telling the engine how to start.
  • Weak performance: A bad sensor can mess with how your engine uses fuel and air, making your car feel less powerful, slower to speed up, or struggle going uphill.
  • Check engine light: When the "check engine" light pops up on your dashboard, it might signal a problem with the sensor.

Should I Fix Or Replace Crankshaft Position Sensor?

Considering fixing or replacing the crankshaft position sensor? I'd suggest replacing it. Trying to repair it could make things worse for the engine.
Getting a new crankshaft position sensor is usually a quick job for a mechanic, taking just a few hours. The cost can vary based on your car's type, but is usually not too expensive.
Sometimes, people try quick fixes like cleaning or adjusting the sensor. While these tricks might help the engine work better for a short while, they won't last. Sooner or later, you'll need to replace the sensor.
If you're not sure how to do these fixes or don't want to risk it, it's smart to let a mechanic handle it. They'll make sure things get fixed properly.

What Happens if You Don't Fix a Crankshaft Sensor?

When your car's crankshaft sensor acts up, it's trouble. It messes with the engine's job, causing misfires and stalling. This can really mess up your engine over time, leading to pricey fixes or even a breakdown.
Plus, your gas mileage takes a hit. The sensor's mix-up means your car uses more gas than it should, costing you money and setting the stage for more engine problems later.
Not just that, it's bad for the environment too. A wonky sensor makes your car emit more bad stuff. That's not cool for nature and might even fail emissions tests, meaning more money out of your pocket.

When to Seek Professional Help

It's important to know when to ask a pro about your car's crankshaft sensor. While simple fixes like cleaning or adjusting it might help a bit, they might not fix the real problem.
If you're not sure how to do these fixes or feel unsure, it's best to talk to a mechanic. They're good at finding problems and suggesting solutions.
Sometimes, changing a broken crankshaft sensor needs special skills that mechanics have. Trying it yourself might damage your engine.
Also, if you think there might be bigger engine problems, like a bad fuel pump or messed-up wiring, it's smart to see a mechanic. They can find out the issue and fix it right.
Remember, asking a pro can prevent more damage and keep your car running well. Mechanics save time, lower risks, and ensure your vehicle gets the right care for better performance.
Can You Drive a Car Without Crankshaft Sensor?
Absolutely not. Driving without a crankshaft sensor is a big no-no. This sensor is super important for your car's engine. It keeps tabs on how the crankshaft moves and how fast. Without it, the engine might not start or act really wonky.
A messed-up sensor means the engine won't know when to do its thing properly. That means your car could stall, lose power, or misfire while you're driving. It's not safe at all.
Sure, you might get away with a short trip without the sensor, but it's risky. Driving like this can make engine problems worse and could end up costing a lot to fix later.
Get that sensor replaced ASAP!
Conclusion
In my search for a temporary fix for a crankshaft position sensor problem, I've tried a few things. The above quick solutions can help a bit with some issues but remember, they're just temporary. They won't really fix the main problem.
Relying too much on these quick fixes might make things worse. Getting a mechanic's help ensures a real fix that lasts longer and avoids just covering up the problem for a short while.
