The intake camshaft opens and closes the intake valve (s) which let the fiel/air mixture into the combustion chamber/cylinder. After mixture is compressed and ignited, the exhaust camshaft opens the exhaust valve to let out burnt mixture/exhaust.

How do I fix the code P0015 on my BMW?
- Resetting the fault codes and performing a road test.
- Replacing camshaft phasers on both camshaft banks.
- Repairing the wiring or connection to the camshaft OCV.
- Replacing the camshaft OCV for bank 1 exhaust camshaft.
- Replacing timing chain and guides.
What is the camshaft position sensor bank 1?
OBD2 Diagnostic Trouble Code P0340 indicates that the Camshaft Position Sensor ‘A’ Circuit Malfunction in Bank 1 has been detected. The camshaft position sensor (CMP sensor) provides information regarding the rotational speed of the camshaft and where the camshaft is positioned in relationship to the crankshaft.
What is camshaft positioning?
A camshaft position sensor is an electronic device that does what it suggests — monitor the camshaft position and speed — and feeds that data to the vehicle’s engine control module (ECM). The ECM needs this data to control how much fuel enters the combustion chamber and ignition (spark) timing to ignite the fuel.
What is the difference between a Stage 1 and Stage 2 camshaft?
Most Stage 1 type modifications are typically in the +10-15% power increase over stock. Stage 2: this is typically referred to an engine with a performance cam upgrade as well as the other components within a Stage 1 combination. A typical Stage 2 has generally +20-25% more HP than stock.
Is it better to have more intake or exhaust?
In general, it’s better to have more intakes than exhausts in order to maintain positive air pressure, which prevents the build up of dust and keeps air circulating.
Can low oil cause P0015?
Code P0015 may be triggered due to several reasons. Here are some of the possible triggers of the code: VVT solenoid (oil control valve) failure. Low engine oil levels.
Are bank 1 and bank 2 camshaft sensors the same?
Q: Are bank 1 and bank 2 sensors the same? Bank 1 and bank 2 have similar sensors. However, bank 1 has two sensors, of which sensor 1 is located near the engine before the catalytic converter, an upstream sensor called pre-CAT, and sensor 2 is located after the catalytic converter called post CAT, a downstream sensor.
How do you check the camshaft sensor on a BMW?
Is camshaft sensor B intake or exhaust?
The camshaft position sensor notes the rate at which the camshaft is spinning, and helps the car’s computer control things like fuel injection and engine timing. Note that the “B” means that this sensor is located in the exhaust side of the cylinder head.
Does camshaft sensor affect idle?
In general, the symptoms of a bad camshaft position sensor can include poor engine performance, lack of power when accelerating, a rough engine when idling and when pulling away, poor fuel economy, engine error codes and a check engine light on the dashboard.
Are there two camshaft position sensors?
A camshaft sensor determines the exact position of your engine’s camshaft, helping your car keep your engine’s combustion running smoothly. Many modern engines have one camshaft sensor for each camshaft. This can mean up to four, although some cars will only have two.
Do you have to relearn a camshaft position sensor?
Camshaft and crankshaft position sensor replacement is often necessary on many cars due to the common results of heat and vibration. However, if the proper relearn process is not performed to account for mechanical wear and manufacturing tolerances when replaced, you may face unnecessary comebacks and complaints.
What are the 2 types of camshaft?
Two major types of camshafts exist: flat tappet and roller. Within those categories are two options: solid or hydraulic—four variations in all. Tappets ride against the camshaft lobes—their movements open and close the valves.
Is camshaft and crankshaft the same?
A camshaft uses egg-shaped “cams” to open and close engine valves (one cam per valve), while a crankshaft converts “cranks” (the up/down motion of the pistons) to rotational motion.
How much HP will a Stage 1 cam add?
How Much HP Does A Stage Cam 1 Add? A stage cam 1 can boost your vehicle by 50 to 100 horsepower. At the same time, it will also produce an increase in the torque output. Add a stage 1 engine to your car, and you’ll experience an improved RPM throttle response.
What does advancing a cam 2 degrees do?
Advancing or retarding the cam pushes the centerline of the camshaft to one side or the other of the crankshaft centerline. This changes the Timing of the valve opening and closing events, in relation to the position of the piston in the cylinder.
How much HP will a Stage 2 cam add?
How much HP does a Stage 2 camshaft add? Stage 2 is upgrading the camshaft while also upgrading the intake and remapping the ECU and exhaust system in order to complete Stage 1. What is this? You can see 20-25% more power from the engine when you’ve completed stages 1 and 2.
How much HP does a better exhaust add?
Everything that comes before the muffler, where the pressure is greatest and performance potential is highest, will remain tight and congested. MagnaFlow, an aftermarket exhaust manufacturer, says that its customers can expect horsepower gains of around 10 percent (which is a pretty commonly-quoted figure).
Does better exhaust increase horsepower?
A cat-back exhaust system improves horsepower because it improves the car’s performance. Your vehicle doesn’t have to work as hard, and the flow of air is increased.
Should I upgrade intake or exhaust first?
If you’ve got a tight budget and care more about providing cooler air to your engine so it can breathe easier, go with an aftermarket cold air intake first. If your budget is less restrictive and you’re more concerned with gaining extra power, aggressive sound and killer looks, install an exhaust system first.
Can low oil damage camshaft?
If the oil level is very low, to the point where the engine overheats however, yes. Excessive heat can cause a camshaft position sensor to fail. More likely in a “low oil level” situation is for the camshaft, lifters, or camshaft variable timing actuator to fail due to inadequate oil pressure and lubrication.
What happens if timing is slightly off?
When any changes are made to the engine of a car, the ignition timing is adjusted accordingly. If not, you could experience several problems with your engine with improper ignition timing like knocking, hard to start, increase fuel usage, overheating, and reduced power.
What causes exhaust camshaft position timing?
The following are the most likely causes: The camshaft’s timing is incorrect. The valve control solenoid has failed and is stuck open. The valve control solenoid system’s wiring is faulty or damaged.
Are both crankshaft sensors the same?
The Crank Sensor is the same exact part.so if you need both just buy 2 of the same part number. if you need just one,it don’t matter which one you ask for,even the parts people can’t screw this up because they are both the same sensor,crank or cam sensor.
