Hi there. The P0016 code is a camshaft/crankshaft correlation bank(1) issue. The P000b is camshaft position slow response bank(1) issue. These codes together are an indication that camshaft timing is out of sync with the crankshaft. This problem has been recognized by the PCM (powertrain control module). This could create a no start condition. There are several possible reasons for these codes. The camshaft timing is variable for increased performance and lower emissions. This is done with a camshaft phaser, which is controlled by an oil control actuator solenoid. Given the low mileage, I would like to believe this is not a mechanical failure, timing chain, chain guide, or phaser malfunction. It could be a VVT solenoid failure and/or camshaft position sensor failure. Proper diagnoses should be performed. I recommend having your vehicle’s Check Engine Light codes inspected and repaired by a certified technician, such as one from YourMechanic, for further help.

The P000B code is a generic powertrain code related to fuel and air metering and auxiliary emissions controls. In this case, it means that engine control module (ECM) has detected a fault with the position and timing of the camshaft.
As stated, the P000B code refers to a camshaft issue. This is very important and warrants immediate attention as camshaft timing is crucial for proper and consistent engine functioning. A vehicle`s PCM monitors the timing of camshaft movement and has a target position registered.
What Does Code P0016 Mean? P0016 definition: The correlation of the camshaft and crankshaft positions on bank 1 is incorrect based on the intake camshaft position sensor.
Codes P000A and P000B are generic codes related to camshaft timing as stated in this article. It can be caused by a number of issues from something as simple as a loose gas cap, to a faulty engine control module (ecm), sometimes referred to as a powertrain control module (pcm).
The OBD error code P000C indicates that your vehicle has a problem with the performance of its engine and the fuel efficiency. This means that the powertrain control module (PCM) which controls the oil control valves has detected a fault with the position and timing of the camshaft.
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.
The basic components you`ll need to inspect are the timing chain and the sensors and tone rings for both the camshaft and crankshaft. These components will all lead to trouble code P0016.
How serious is the P0016 code? This particular OBD-II trouble code is deemed to be severe as your camshaft and crankshaft aren`t lining up correctly. The timing chain may have issues with guides or tensioners, leading to engine damage if the valves hit the pistons.
If the crank position sensor isn`t replaced, the problems with hard starting, poor fuel economy, rough running, stalling and vibration will just get worse. The engine will also misfire, since the sensor isn`t sending the computer accurate information on piston position, which will throw off spark and fuel metering.
These codes are both camshaft and crankshaft correlation codes. While these codes can be caused by a faulty sensor, more often they indicate a problem with the engine timing components. This could be anything from a stretched timing chain to a failed oil control valve, as you mentioned.
How Serious Is the P000A Code? A P000A code can be very serious for your car in the long term, but you will probably find that you can drive your car without incident for a few weeks before it begins to display the previously mentioned symptoms.
What Does Code P0019 Mean? P0019 definition: The correlation of the camshaft and crankshaft positions on bank 2 is incorrect based on the intake camshaft position sensor. Issue Severity: SEVERE – Stop driving immediately.
P0390 code definition
The P0390 code is stored if the powertrain control module (PCM) does not detect the camshaft position sensor signal within a few seconds of cranking. This code is specific to sensor “B,” which, in general, is the exhaust camshaft sensor.
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.
Bank 1 is the side of your engine that has the cylinder 1, while sensor B refers to the exhaust camshaft side. Some car manufacturers have their own description of the P0017 code, such as GM (more specifically, Chevrolet).
Unfortunately, there`s no way to reset a camshaft position sensor. If you`re having camshaft issues (check engine light on, acceleration trouble, sputtering and stalling, etc.), you`ll have to replace the part entirely.
If you ignore the symptoms listed here and your camshaft position sensor fails, your vehicle will not start. As a camshaft position sensor weakens, so does the data it transmits to the ECM. Eventually the data signal becomes so weak the ECM switches off fuel and spark delivery, and your engine will not start.
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.
Camshaft timing is out of position because the timing chain jumped teeth. Defective or corroded wiring or connections. Bad sensor issue (crankshaft position sensor or camshaft position sensor)
In general, the P0016 is the OBD-II generic code indicates that the camshaft position sensor for bank 1 does not correlate to the signal from the crankshaft position sensor.
If your crankshaft sensor is not working properly, the motor control unit in your vehicle won`t be able to execute the changes to the fuel injection or to the spark timing whenever the engine speed climbs.
Engine Misfires: A failing camshaft position sensor can cause your engine to misfire. Transmission Shifting Problems: The data sent to the engine control module can stop the transmission from shifting properly.
A stretched timing chain contributes to poor engine performance and increased emissions, triggering the check engine light and the storing of a diagnostic trouble code. A mechanic will need to inspect the code and prescribe the necessary repairs.
The average cost for camshaft sensor replacement ranges from $105 to $226, depending on whether you go to the mechanic or do it yourself. This price range is based on national averages for all vehicles and does not factor in taxes, fees, or make and model.
