Camshaft Sensor

The camshaft regulates the four strokes of the ignition process (Intake, Compression, Power, and Exhaust) by controlling the intake and exhaust valves of an internal combustion engine. The camshaft rotates at half the speed of the crankshaft therefore, all camshafts must be "timed" properly to avoid serious engine damage. Camshaft installation is sophisticated engine work, but you can learn how to approach the task as safely as possible for your make and model, as well as some general recommendations on how to get the job done well.

What role does a camshaft have in engine performance?

The camshaft regulates the opening and shutting of the valves in either a push rod or an overhead cam engine. This, in turn, impacts engine performance, fuel efficiency, and emissions by controlling the flow of air and fuel into and out of the engine.

What are the signs and symptoms of a malfunctioning camshaft?

The vehicle no longer drives as it once did. Your camshaft position sensor may be failing if your car idles harshly, stalls regularly, has a drop-in engine power, stumbles frequently, has poor fuel efficiency, or accelerates slowly. The Check Engine Light illuminates and the vehicle will not start.

How does a camshaft work?

The lobes are the most important components of every camshaft. The lobes open and close the intake and exhaust valves in synchrony with the piston as the camshaft spins. It turns out that the geometry of the cam lobes has a direct impact on how the engine runs at different speeds.

What is the function of a camshaft?

The opening and shutting of a cylinder's valves is controlled by two overhead cams. On a four-cylinder engine, the smaller valve timing gear is on the crankshaft, while the bigger gear is on the camshaft. Because of the gear ratio, the camshaft rotates at half the speed of the crankshaft. Engines with dual overhead camshafts (DOHC) often have superior performance, make more power, and can operate at higher speeds. To open the valves, the camshaft utilises spinning lobes called cams that press against them.

The valve train is a group of synchronised components that work together to optimise the engine's timing and performance. The valve train controls fuel intake, compression, ignition, and waste expulsion by opening and shutting a sequence of valves. It is made up of multiple valves, rocker arms, pushrods, lifters, and at least one camshaft. The operations and timings monitored by the valve train, which are synchronised to the crankshaft by a chain, belt, or gear array, speed up or slow down to maximise performance and efficiency.

The valve train's motions and uniformity might begin to deteriorate over time as parts wear out. Valve openings that are too early, too late, too short, or too long can have an instant impact on a vehicle's performance and could cause catastrophic engine damage. Valve trains will alter depending on the engine arrangement.

What causes the failure of a camshaft?

A connecting rod or other spinning element falling free and hitting the camshaft is the most common cause of a damaged camshaft. Because of a crack or fracture in the cam caused by rough treatment during shipment or inappropriate handling before to installation, the cam may break after a short period of operation.

What happens if a camshaft fails?

As the signal from the camshaft position sensor deteriorates, the signal it sends to the vehicle's ECM deteriorates as well. The indicator will eventually fade to the point where it will turn off, along with the engine. This might happen when you're driving or while the vehicle is parked. The latter is potentially harmful.

How can I tell if my camshaft is defective?

The Signs and Symptoms of a Faulty Camshaft Position Sensor:

A malfunctioning camshaft in some cars may lock the gearbox in a single gear until the engine is turned off and restarted.
If the sensor fails while your vehicle is in motion, you may notice the vehicle jerking and losing power.
You may notice a substantial reduction in engine power.

What happens when the camshaft timing is advanced?

When a camshaft's timing is advanced or deferred from its initial zero position, valve actions occur earlier or later in the engine's cycle. The intake valve, on the other hand, will close later if the camshaft timing is delayed, generally during the compression stroke.

Free Collection and Delivery with Camshaft Sensor Replacement

Having to bring your vehicle to the garage is sometimes the toughest part of getting it fixed. As a result, we are pleased to provide a free collection and delivery service to our clients. If you schedule a collection, we will pick up your vehicle from your home or place of business, drive it to our facility, do any required work (after consulting with you), and return it to you at the end of the day.

For a modest cost, we can tow, jump start, or repair your car if it is having troubles or has broken down. If we are unable to start your car, we may arrange for a local recovery company to collect it at a very reasonable cost.

Don't want to ruin your day off?
You don't have enough time to get your vehicle serviced or repaired?
Do you have trouble getting to and from your garage?

With our Free Collection and Delivery Service, we can collect from either your place of work or your home location, and we feel we provide a valued product at Car Service and Repair. Please contact us if you are unclear whether the address from which you wish to have your car collected is within our service area.

Car Service and Repair operates a fleet of pool cars with a dedicated driver, thus wherever we collect from, we must be allowed to leave one of our pool vehicles either in your business car park / parking spot, or if in a residential area, at your house or on the road with a permission if necessary. We'd appreciate it if you could keep this in mind when making a booking for our free collection and delivery service.
