Cruise control can be a lifesaver on long drives, letting you relax, saving energy, and keeping the car moving steadily. However, cruise control problems can quickly turn that dream into a nightmare. If cruise control suddenly stops working, the problem likely lies with the speed sensor.
A faulty speed sensor can create a ripple effect, impacting the performance of various interconnected parts. For optimal resolution, trust a certified mechanic to handle the situation.
How Does A Speed Sensor Affect Cruise Control?
Also known as an output shaft speed sensor or wheel speed sensor, a vehicle speed sensor sends signals to your vehicle’s onboard computer about how fast you’re moving. It is a tiny component found in your car’s transmission.
It measures how fast the gears rotate in the transmission system. Then, it turns the speed measurement into an analog or wave signal to the car’s electronic control units (ECUs).
Then, the ECUs refer to the signal and adjust the car’s speedometer readings, ABS module, and transmission system accordingly. The speed sensor also regulates the cruise control system.
The cruise control system allows you to keep your current vehicle speed without any input from your end. But, of course, you must keep your eyes on the road and monitor changing traffic and driving conditions.
So, if this sensitive component malfunctions, your car cannot maintain the perfect speed as it cruises on the road.
Modern vehicles come with various vehicle speed sensors. For example, the cruise control module (CCM) may be getting signals from the engine control module (ECM), transmission, or instrument cluster to do its job.
Losing this signal means the CCM can’t detect the speed of your car, which disables the cruise control feature. Bring your vehicle in and let our mechanics fix the problem immediately.
What Causes Speed Sensor Failure?
Imagine cruising down the road when suddenly, your car starts acting up, with erratic speedometer readings and problematic cruise control. Don’t panic! The culprit might be your vehicle’s speed sensor.
It’s a vital component communicating with numerous systems like anti-lock brakes, ignition timing, and transmission. To keep your drive smooth and safe, familiarize yourself with the possible causes of speed sensor failure and know when to bring it to a mechanic.
A speed sensor can sustain internal damages that result in abnormal or no signal output. In some instances, the problem lies with the sensor. For example, constant exposure to the elements may cause the sensor to crack, warranting an immediate replacement.
Poor vehicle maintenance increases the possibility of speed sensor failure. For example, it can’t provide accurate readings when covered with dirt and gunk.
Can You Still Drive A Faulty Speed Sensor?
Driving with a defective speed sensor poses a significant hazard to you and your passengers. This critical device monitors speed to ensure safety and determine when brakes are applied.
Cruising with a malfunctioning speed sensor can spell disaster, as it prevents the vehicle’s computer from accurately gauging speed and adjusting engine power or braking accordingly. With compromised safety systems, you may be teetering on the edge of a catastrophic incident.
Take your vehicle to a mechanic for immediate assistance. Remember that aside from experiencing cruise control problems, a faulty speed sensor prevents your engine and transmission from getting the necessary information to perform optimally.
Cost of Speed Sensor Replacement
How much you need to pay to replace the speed sensor depends on the make and model of your car and the type of sensor you’re using.
It’s not as expensive as a master cylinder or brake line replacement, but getting a new speed sensor may cost you at least $200. We’ll check your vehicle and provide an estimate and explain what we can do to fix the problem.
There’s no standard guideline on how often you need to replace the speed sensor. How long this component lasts depends on your driving conditions.
Other factors can shorten the lifespan of the speed sensor. For example, incorrect installation, electrical faults, contaminated speed sensor tips, and poor vehicle maintenance can cause a faulty speed sensor.
A fault speed sensor prevents you from enjoying the full features of cruise control. In addition, if you’re driving around with a defective component, you won’t know how fast you’re going, compromising your safety.
Although replacing the speed sensor on your own is an option, we recommend seeking the expertise of a skilled technician. If you try to perform the replacement yourself, you may create a more significant problem and compromise your road safety.
Accurate Service Inc.’s mechanics will check the speed sensor and make the necessary repairs and replacements. We provide high-quality services and use state-of-the-art equipment to do the job correctly.
Our highly-skilled technicians disconnect gently, remove the speed sensor from the transmission system, and remove the connector to the car’s wiring. Then, they install the new sensor and take your car out for a test drive, ensuring the cruise control system works perfectly.
