Temporary Fix For Crankshaft Position Sensor: The 3 Easiest Methods!

We bet many of you don’t know how to deal with a failing crankshaft position sensor and usually be stranded on the roadside. Indeed, many car drivers don’t even know the existence of this device and what it does. Today, Driverevolve will discuss the basics of a crankshaft position sensor, common causes of a bad one, and the temporary fix for crankshaft position sensor. 

What Is A Crankshaft Position Sensor? 

These sensors are gadgets that track the placement and measure the rotational pace of the crankshaft in gas and diesel inbuilt combustors. Your car’s ECU will use such information to regulate the schedule of fuel injectors and other vehicle features. 

Without a crankshaft position sensor, the crankshaft message will disappear, which might cause the engine to stop working immediately.

The placement of your crankshaft position sensor differs from car to car. As it must be near your crankshaft, it is usually on the front undersurface of your motor. On a few models, it is fixed to the scheduling lid or installed at the back or side of the engine.

So, where is the crankshaft position sensor located

The placement of your crankshaft position sensor differs from car to car. As it must be near your crankshaft, it is usually on the front undersurface of your motor. On a few models, it is fixed to the scheduling lid or installed at the back or side of the engine.

What Causes Crankshaft Sensor To Go Bad? 

Exposure To Extreme Temperatures 

Because of its location inside the engine, this detector is frequently swamped in high temperatures from the motor and its neighboring parts.

There is a tiny circuit system within the crankshaft detector with electrical copper wires, all covered in plastic. When the temperatures get extreme, it completely melts the crank sensing device’s plastic cover, causing circuitry damage in the long run.

Problems With The Wiring Harness 

The wire harness connects the crankshaft detector to the car’s controllers – the ECU – to communicate measured data. Although it is built to withstand brutal environments, a faulty circuitry thread can affect the crankshaft sensor. Alternatively, the device may still function normally, but it will be unable to send information back to the electronic control unit.

The wiring harness may have come disconnected from its socket, or it may have deteriorated and broken down. Any clutter in the engine compartment, such as grease or impurities, might take its toll on the cabling over time. Overall, it could contribute to the inaccurate voltage being operated inside the mechanism or problems with the crankshaft detector's return loop.

Overall, it could contribute to the inaccurate voltage being operated inside the mechanism or problems with the crankshaft detector’s return loop.

Circuitry Issues 

The circuit board within the crankshaft detector is also subject to deterioration. It depends on the health of motorized and digital parts to transmit data back to the controller. The circuitry is susceptible to disturbances; thus, a slight collision could cause damage to its cables.

Maybe it has deteriorated and is short-circuiting, or it has fallen away from its sockets. Inaccurate – that is, too little or too much – power output sent via power cables could also impair the device’s status. These can cause the still-operational crankshaft detector to wear out quicker and inevitably screw up completely.

Broken Timing Belt 

The timing harness, also known as the timing system, is in charge of syncing the activities of the driveshaft on top and the crankshaft on the bottom.  

The prolonged deterioration is powerful enough to break it; thus, frequent check-ups and servicing are advisable. Another possible case is that the timing string snaps due to a crash.

When it snaps, the return power may be powerful enough to encase the strap or loop around the crank sensing device. The pressure placed on the plastic detector is sufficient to snap it.

When it snaps, the return power may be powerful enough to encase the strap or loop around the crank sensing device. The pressure placed on the plastic detector is sufficient to snap it.

If this is not the case, expect the broken belt or loop to affect the detector while moving at high velocity. This effect, once again, is more than enough to shake it or induce significant damage to the device.

The Temporary Fixes For Crankshaft Position Sensor 

There are a couple of things you might try to address the issue temporarily. It is essential to mention that those techniques will only get your car to your desired location; they will not provide a long-term solution because you can’t repair the detector.

If your crankshaft position sensor is compromised, it must be replaced as soon as possible.

Shut The Vehicle Down

This technique will be used if the vehicle begins to jerk or if there is an unexpected pop-up on the console center and the engine light alert appears.

In either scenario, turn off the car and investigate what went awry. A failure in the crankshaft position detector is most likely to blame for the issue.

Turning off the car allows the operating motor to halt and stop working. Afterward, switch on the vehicle for a few minutes, and it should operate smoothly again.

Disconnect the Crankshaft Position Sensor

If your vehicle doesn’t start due to a faulty crankshaft position detector, you might detach the device and restart the engine. The car could start by utilizing its default routing.

Refuel Your Car 

A faulty crankshaft position detector will result in a rise in gas mileage. The greater the jump in fuel economy, the less gasoline is available inside the car’s gas tank.

To avoid an unexpected run out of gasoline in the car, visit your local refueling facility and refuel it. This will help you reach your desired location. However, keep in mind that this strategy is quite costly, especially if you use it for an extended period.

Cooling

A faulty crankshaft position sensor might result in extreme temperatures in the engine. Overheating engines might cause car failures. Cooling your automobile sufficiently will allow it to operate for a prolonged period. 

Crankshaft Position Sensor Replacement Cost 

Frankly, your crankshaft position detector is not a part you can easily fix if something goes wrong. On a positive note, the expense of a replacement isn’t outrageously costly. 

In most cases, a crank sensor replacement will charge between $120 and $300 (similar to the tie rod end replacement cost) in components and service costs. This is relatively affordable compared to the high heater replacement cost.

Even so, a brand new device can at least ensure that it will function efficiently right out of the box. On the other hand, if you prefer to get a specialist to change it for you, the service fees will range from $45 to $180 for 60 minutes in general.

Indeed, the device itself costs from $75 to $120 and is easily found on the racks of most automotive parts shops. You could save a few bucks by purchasing a secondhand but excellently functional detector.

Wrapping Up 

Hopefully, today’s post has helped you understand the crankshaft position sensor, its usage and importance, the 6 common causes of a broken one, and the temporary fix for crankshaft position sensor if it fails. Although it’s among the most neglected parts of the car, the whole mechanism will stall shortly after it fails. Thus, pay heed to this small but mighty component.
