Reminders When Buying an RPM Sensor

Besides heavy traffic, there's nothing that frustrates drivers more than engine problems. After all, engine issues can give you quite a headache. Aside from experiencing difficulty in driving (if your car is still drivable, that is), you'd also have to figure out what part is causing the problem. And mind you, diagnosing engine issues isn't that straightforward since there are many components that affect engine performance. With that said, you'd have to observe the problems closely in order to come up with the correct diagnosis.

If your engine problems consist of misfiring, rough idling, poor gas mileage, or if it won't start at all, then there's a good chance that it's a faulty RPM sensor (also known as crankshaft position sensor) that's causing the problems.

What's a RPM Sensor?

The RPM sensor is an internal electronic device that measures an engine crankshaft's rate of revolutions per minute. It provides the computer with information regarding the current position of the crankshaft so that engine cylinders can be fired up in the correct order. Because of its particularly important role, the RPM sensor is one of the worst things that can become busted in your vehicle. A faulty sensor results in inaccurate crankshaft position data (or none at all), which can severely affect engine function.

Since you can't repair a broken RPM sensor, you've got no choice but to replace it.

Get an OEM Replacement

The kind of RPM sensor you'll need depends on the type of engine you have (the location of RPM sensors varies from model to model for that reason). That's why it's best to purchase an OEM replacement so that you won't have major issues in the installation process. An OEM RPM sensor should fit perfectly in your vehicle. It's also of superior quality; hence an OEM RPM sensor is the most ideal replacement.

RPM sensors are generally pricey. With that said, OEM RPM sensors will give you the most bang for your buck. How much you'll have to spend for an OEM RPM sensor depends on the kind of sensor that's appropriate for your car's engine type.

How to Replace the RPM Sensor of your Fiat (JTD Engine)

Having engine trouble? That's always a pain. To make things worse, there are numerous possible causes for it, which makes the problem tougher to diagnose. But if your engine constantly misfires, hesitates, or won't start at all (the worst-case scenario), then there's a big possibility that it's the RPM sensor that's busted.

The RPM sensor is arguably the most vital sensor in your vehicle. It provides the computer information regarding the crankshaft's present position so that engine cylinders can be fired up in the correct order. If the RPM sensor is faulty, then it wouldn't be able to send accurate data-if it can send anything at all-to the computer. That of course results in the problems noted earlier. And since you can't repair RPM sensors, you have no choice but to replace it. Don't worry though as installing a new sensor isn't difficult. We'll guide you step by step on how to do it.

Difficulty level: Moderate

Tools:
  • Jack
  • Jack stands
  • Torx screwdriver
  • Socket

Step 1: Park your car on a level surface.

Step 2: Grab your jack and start lifting the front end of your car. Place jack stands underneath afterwards.

Step 3: Of course, going under the car is the next step. Be sure to bring your torx screwdriver and socket with you as you'll need them to remove the undertray.

Step 4: Once the undertray has been taken out, turn your attention to the back part of the engine. You should find a black cable and a red cable that are attached to a plastic mounting bracket. Unbolt the said bracket then unclip the black cable (the RPM sensor connector) from it. Detach the RPM sensor connector after that.

Step 5: Follow the other end of the black cable towards the rear left hand side of the engine (near the starter motor). It should lead you to the RPM sensor. Once you've found the sensor, grab your torx screwdriver to detach it from the engine. Be careful when pulling it out as there may be oil around the sensor. We're sure you wouldn't want oil to drip on your face, especially your eyes.

Step 6: You can now install your new RPM sensor. Make sure to secure it properly. After that, put back everything that you took out earlier.

With your newly installed RPM sensor, you shouldn't experience engine problems anymore. But to be sure, test drive your car afterwards.
