A bad cam-sensing device affects the transmission. The engine control module does not receive correct cam speed and position data, which affects its ability to control ignition and combustion. That, in turn, causes shifting problems. Your car may also go into limp mode to prevent further damage.

The ECM (Engine Control Module) relies on various sensors to control engine operation. One of them is the camshaft sensor, abbreviated as CMP. This part provides the ECM with cam position and speed, enabling it to regulate combustion. As such, its failure can affect the car’s performance in many ways, exhibiting cam sensor symptoms. They include:

The CPS also fails if its electrical connections are faulty due to corrosion or breakage. Regardless of the cause of failure, you must quickly act if you notice any symptoms.

Several things can cause the CMP to fail. Given its location, it gets subjected to harsh conditions like heat, vibrations, and sometimes metallic debris. That can take a toll on it, causing it to fail over time.

Reduced engine power, starting problems, increased emissions — camshaft sensor symptoms can show in many ways. They mainly indicate a problem with the part, which, if not operational, causes the ECM to lose proper control of engine systems. Here’s more about these signs.

A failing CMP sensor cannot send correct cam data to the ECM. As a result, the engine suffers. The combustion process becomes inefficient, leading to problems like reduced power, misfire, and increased emissions.

Greases with petroleum oil bases have high dN capability (recommended for light to heavy loads and moderate to high speeds)

With the fuel injection and ignition systems not working correctly, the engine becomes less efficient, increasing the amount of emissions. As a result, failing the emission test is one of the most common symptoms to look out for.

In the worst of situations, your car may stall. Stalling indicates the fuel injectors are not delivering fuel as they should, with the possibility of the sensor being the cause. This problem can be dangerous, and a proper diagnosis is required.

The maximum usable operating speed of a grease lubricant is dependent on the type of base oil. The speed factor is a function of the bore of the bearing (d) in millimeters (mm) and the speed of the bearing (N) in revolutions per minute (rpm) where:

There is the smell of unburned fuel. This symptom shows an incomplete combustion process, leading to some fuel mixture reaching the existing pipe. But while this is one of the cam sensor fault symptoms to look out for, it’s good to note that other things can cause it.

New Hampshire Ball Bearings, Inc. (NHBB) is a leading manufacturer of precision bearings and complex bearing assemblies for the global aerospace, defense, medical, and high technology markets. The company is a subsidiary of MinebeaMitsumi Inc. and an integral part of the global brand, MinebeaMitsumi Aerospace.

The standard quantity of oil varies with bearing size, but is approximately one drop (3-6 mg) per bearing up to R-2 size and two drops (6-12 mg) for larger sizes. The standard quantity of grease is 25-35% of the bearing's internal free volume. For nonstandard applications, please consult the factory for specific lube fill recommendations.

After determining the lube-type and fill appropriate for the speed of the application (see table below), consult the table on the Cages page to select a suitable retainer, as it provides the maximum operating temperatures and speeds for each retainer type. To verify limiting speeds for unique operating conditions not covered here, and for full ball complement-type ball bearings, please consult the factory.

Centrifuging an oil-lubricated bearing removes excess oil and leaves only a very thin film on all surfaces. This method is used on very low torque bearings and can be specified for critical applications.

Packing approximately 1/4 to 1/3 of a ball bearing's internal free volume with grease is one of the most common methods of lubrication. Grease quantity can be controlled by the use of special lubrication equipment.

Oil is the basic lubricant for ball bearings, and NHBB offers both petroleum-based and synthetic oils such as diesters, silicone polymers and fluorinated compounds. In general, diesters have better low temperature properties, lower volatility and better temperature/viscosity characteristics than petroleum-based oils. Silicones and fluorinated compounds possess even lower volatility and wider temperature/viscosity properties.

The engine becomes inefficient, and your car consumes more fuel than usual. The fuel economy problem results from data inaccuracies caused by the CMP. It shows the ECU is providing incorrect instructions to time various processes, including gas intake and ignition.

Grease consists of oil lubrication with added thickeners that prevent migration from the lubrication site, resulting in longer life. Grease is used in situations where frequent replenishment of the lubricant is undesirable or impossible. The operative properties of grease depend almost wholly on the choice of base oil. Other factors being equal, the use of grease instead of oil results in higher starting and running torque and can limit the bearing to lower speeds.

A failing CMP can cause your engine to malfunction or even get damaged. Your car loses power, misfires, and may even stall while driving. The symptoms explained in this article should help you tell when it starts to fail.

Based on the discussed camshaft sensor symptoms, you may suspect yours to be failing and wondering if you can still use the vehicle. So, can you drive with a bad CMP? If so, for how long?

With no proper engine control, your car could become dangerous to drive. Its failure also causes issues that could quickly damage engine components. In some vehicles, failure may cause the car to enter “limp mode” and prevent further damage.

Oil, grease, and dry film are the three main types of lubricants used in miniature & instrument ball bearings. Oil lubricants include petroleum and synthetic varieties. Selecting the most suitable lubricant is critical to achieving the full rated life of the bearing and optimal performance of the assembly, but choosing from the hundreds available can be an overwhelming task.  The charts published below list a small selection of lubricants we use regularly. They cover a wide range of temperatures, rotational speeds, load conditions, and assembly designs.  Please contact NHBB Precision Division's Applications Engineering department before making your final selection.

The engine power reduces, and you have difficulty accelerating. It’s one of the most probable camshaft position sensor symptoms you should not overlook. In addition to causing a drop in your engine’s performance, it could cause it to get damaged.

The car fails to start, even with the starting system working correctly. The problem happens when the CMP cannot feed the ECM with camshaft position information, resulting in fuel injection and sparking issues.

Below is a table of commercial and military lubricants and their recommended uses. When ball bearings are ordered without a specified lubricant, it is the policy of NHBB to lubricate with MIL-PRF-6085 oil. Company standard lubricants are LO1 (Winsor Lube L-245X oil) per MIL-PRF-6085 and LG68 (Royco 27 grease) per MIL-PRF-23827. For nonstandard lubricants, please consult the factory to select an appropriate type.

We do not recommend operating your car if the ECU cannot sense the position of the cam and its speed. In addition to risking engine damage, your vehicle could stall due to a disruption of the combustion process.

The engine has a rough idle, showing a disrupted combustion process. In addition, a cylinder may occasionally fail to fire, indicating an ignition timing problem. The ECM could have issued the wrong commands due to a failing camshaft position sensor or other causes.

Solid film lubricants are any non-fluids used to prevent wear and reduce friction. They can range from simple sacrificial cages to graphite powder and ion sputtering. Each type must be engineered for the specific application. Solid film lubricants have definite advantages. They are very useful in areas of temperature extremes, vacuum, radiation, pressure, or harsh environments where conventional lubricants would fail. In addition, these lubricants do not deteriorate in storage.

No exact formula exists for calculating the maximum operating speed of a ball bearing. Sustained high speed performance is dependent on the specific properties of the bearing, shaft, housing and other components, as well as the application's specific operating conditions. The retainer is the feature of a ball bearing that most affects rotational speed, followed by tolerance grade and lubricant type and fill. The dimensional accuracy of mating components limits speeds, as does the application's maximum operating temperature. If properly installed and lubricated, high precision ball bearings will operate for long periods of time at high speeds.

The CPS is not repairable; you can only replace it with a new one. It’s also a relatively inexpensive part and won’t cost much compared to the problems it causes. Here is how to replace one.

The ECM constantly checks the sensor’s health. Upon detecting a problem, it turns on a check engine light. But while that is possible, it’s good to note several other issues that can cause the engine light. Confirm if the CMP is to blame.

The best advice is to change the part as soon as you can. CMP replacement should cost you between $100 and $150 in labor charges. The part itself goes for less than $50

For ball bearings containing porous cages, vacuum impregnation forces lubricant into the pores, using the cage as an oil reservoir. When used with a greased bearing, this method prevents the cage material from leaching oil from the lubricant. Normally, the base oil of the grease is used in the cage to prevent incompatibility.
