Quick Tips in Buying an Impulse Sender
Difficulty in starting, rough idle, and low fuel mileage-these are some of the most common automotive problems. They're also among the automotive issues that give the worst headaches to car owners. And all of those can happen to you at the same time if your vehicle's impulse sender gives out.
The impulse sender may be a little-known automotive component, but its role in an automobile isn't
little by any means. The impulse sender, also known as the crankshaft position sensor, monitors the engine RPM and aids the crankshaft in maintaining correct timing and engine valve clearance. Needless to say, your car won't be able to function properly if the impulse sender is broken. It's best to replace it as soon as you can.
Before you buy a replacement, make sure that it's indeed a faulty impulse sender that's causing the issues mentioned earlier. As you know, the symptoms of a busted impulse sender resemble those of other broken automotive components. Because of that, you may mistakenly get a brand-new impulse sender when it's the spark plug that's the problem. So before anything else, use a diagnostic sensor to identify if it's the impulse sender that's causing your automotive woes.
There are three main types of impulse senders-hall effect sensor (the most common), optical sensor, and inductive sensor. There are a few specialized variants as well. The type that you'll need to purchase depends on the make and model of your vehicle.
Get an OEM Replacement
To ensure that you won't have difficulty in installing a brand-new impulse sender, get an OEM replacement. It's best to get a replacement that resembles your old one, and an OEM impulse sender is just that. An OEM impulse sender is durable, which means you won't have to replace it again anytime soon, and should fit perfectly in your car.
The cost of OEM impulse senders varies greatly. You could spend as low as approximately $25 or as much as $80. How much you'll have to shell out depends on the make and model of your vehicle.
How to Replace an Impulse Sender in a Honda Civic
A busted impulse sender (also known as a crankshaft position sensor) should never be taken lightly. The impulse sender is responsible for monitoring engine RPM and assisting the crankshaft to maintain correct timing and engine valve clearance. Because of those important functions, it's not surprising if major problems occur when the impulse sender becomes faulty.
Some of those problems include:
- Difficulty in starting
- Rough idle and acceleration
- Decreased fuel mileage
Once you've confirmed that your Civic's impulse sender is broken, don't delay in buying a replacement and getting to work. You'll want to install a new impulse sender in place of your old one as soon as you can. We'll guide you step by step on how to do that.
Difficulty level: Moderate Tools:
- Jack stands (preferably at least 6)
- Socket wrench
Step 1: Before anything else, park your Civic on a level surface. Chock the wheels and activate the parking brake afterwards.
Step 2: To ensure your safety, disconnect the negative battery cable.
Step 3: Grab your jack and start lifting the front end of your Civic. Once it has been raised properly, place two jack stands underneath the front jacking plate (it's marked by an arrow). After that, move on to the rear end of your vehicle and lift it as well. Use jack stands on both the rear and the side mounting areas (they should be marked like the front jacking plate).
Step 4: Now, grab your socket wrench and use it to remove the engine brush cover, which is located under the front area of the engine. To make things easier, you may choose to take out the driving belt as well.
Step 5: In order to gain access to the impulse sender, you'll have to take out both the lower timing belt cover and the crankshaft pulley. After that, detach the impulse sender?s electrical modules (located near the alternator).
Step 6: Take your socket wrench again and use it to remove the impulse sender. Put your brand-new impulse sender in the place of the old one afterwards.
Step 7: It's time to put back everything that you took out earlier. Reattach the electrical modules, the crankshaft pulley, the lower timing belt cover, and the driving belt (if you took it out).
Step 8: Once everything is back where it should be, use your jack to lower your Civic to the ground (start from the rear). Remove the jack stands afterwards and reconnect the negative battery cable.
