Select a certified professional
The new car smell may be long gone, but that doesn’t mean your car doesn’t deserve the best – even if it’s seen better days. You don’t want just anyone popping the hood and poking around. Look for a certified mechanic who has experience working with your car’s make and model.
Also, keep in mind, there are many different areas a technician can specialize in. You’ll want to choose someone who has A8 Engine Performance certification.
Do they have a good reputation?
Recommendations, either via word-of-mouth or internet reviews, are a great way to find a stellar mechanic. If a repair business has been around for a long time and has a devoted following, you can bet they operate with intelligence and integrity.
Do they seem professional?
Repair in your driveway should be a professional experience. You’ll know you’re in good hands when a mechanic, in a clean uniform, arrives in a company vehicle equipped with tools and car parts to complete the job. Time to raise your standards.
Don’t be left guessing about quality
rank sensor quality varies, as does the caliber of the work being performed. Always ask about warranties when you schedule an appointment. Warranties offer quality assurance and protect you in the rare case that something goes wrong with your repair.

Look for a certified mechanic
Check to make sure the shop is working with only the best, aka ASE certified professionals. In particular, you’ll want to ask whether the mechanic assigned to your car has A8 engine performance certification. And if the shop doesn’t have the right credentials, move on.
Reputation is everything
The best shops have a loyal clientele – and a packed schedule to prove it. Online recommendations or word-of-mouth suggestions will help you find a mechanic with an outstanding reputation.
Are they helpful?
A good shop will take the time to explain the diagnosis and replacement of your crankshaft sensor in detail. They will also be honest about pricing (including giving you an estimate for parts and labor) and won’t try to add on any unnecessary repairs.
Do they offer a warranty?
You don’t want to be stranded due to a low-quality crankshaft sensor or poor workmanship. Ask about warranty coverage when you schedule your appointment. A sound warranty provides peace of mind that you’re getting an OEM-grade crank sensor and expert repair.
What is a Crankshaft Sensor?
Okay, hang in here with me, because the crankshaft sensor, while sounding simple enough, is kind of a lot to take in.
The crankshaft sensor works with the engine control module (ECM). The ECM needs two key pieces of information: The speed of the engine and the position of the crankshaft. The crankshaft position sensor measures both parameters.
The sensor works in harmony with a notched or tooth wheel, which is often located on either the harmonic balancer, or the crankshaft itself. As the wheel rotates, the crankshaft sensor identifies both the position and the speed of the crankshaft. It sends that information to the ECM, which then knows when to fire the spark plugs.
Still with me? Great, because there’s more. The ECM gets a lot of other information from the crankshaft sensor. For example, it can use the sensor to detect engine misfires, and to determine fuel injector control.
Signs of a failing Crankshaft Sensor
Car won’t start
It might shock you to learn that when your car won’t start, something might be wrong. That something could be the crankshaft sensor.
If your car is stalling like a 16-year old trying to climb a hill in a manual transmission, then you might have a faulty crankshaft sensor. Or, if you’re driving a stick shift, it might not be the sensor. It might be that you’re bad at this.
Poor engine performance
I know you take pride in your performance when the light turns green, even if no one else does. So it hurts when your engine lets you down. If it does, it might be due to a malfunctioning crankshaft sensor.
If your tachometer seems wildly inaccurate, it’s probably not you making up things. It might be, but it’s more likely to be a crankshaft sensor issue.
Check engine light
You thought you could make it through this article without the check engine light being mentioned, didn’t you? Tough break, pal. Pay attention to your check engine light, as unassuming as it may appear.
How urgent is a Crankshaft Sensor replacement?
Do you like having a car that stalls and sometimes won’t start? Is that fun for you? If so, then by all means, ignore your crankshaft sensor. It’s unlikely to cause much further damage.
But if you prefer effectively use your car, then get the sensor replaced.
