P0368 is a diagnostic trouble code (DTC) for "Camshaft Position Sensor "B" Circuit High (Bank 1)". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $114.99 . Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.0 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
Your powertrain control module (PCM) has detected an incorrect voltage reading or waveform from your vehicle’s camshaft position sensor circuit for camshaft sensor “B” in engine bank one. The camshaft position sensor is a stationary electro-magnetic sensor that operates in tandem with notches on your camshaft. These notches on the camshaft interfere with the sensor’s magnetic field.
Abnormalities in your vehicle’s system reference voltage that exceed ten percent of the manufacturer’s reference value could cause a P0368 to be stored and for your Check Engine or Service Light to come on. Basically the powertrain control module (PCM) will read and translate these abnormalities to mean that you have an incorrect camshaft position.
The most common cause for a P0368 code has to do with oil and other engine fluids spilling onto your vehicle’s wiring, sensors, or electrical connectors. This usually leads to grounded, shorted, or broken wiring, and shorted or loose electrical connectors. typically causes grounded, broken, or shorted wiring, along with loose or shorted electrical connectors.
Some symptoms associated with this code may include an engine that idles loudly and roughly, a delay when starting your vehicle, hesitant or choppy acceleration, a car that will not start, and lower engine performance.
In order to diagnose this problem accurately, you will need specific tools, such as a digital volt/ohmmeter, a scanner, and an oscilloscope. Always begin with a careful visual inspection of your connectors and wiring, and be sure to replace or repair any damaged, corroded, or shorted wiring that you see. If you believe you have an intermittent condition, you could use the oscilloscope to monitor the waveforms created by your vehicle’s distributor, camshaft, and crankshaft sensors. Pay attention to glitches or inconsistencies, and look for areas of circuitry that appear to be contaminated with antifreeze, oil, or power steering fluid that has spilled from your engine.
It is important to note that a P0368 code pertains to the entire camshaft position sensor circuit. This means that it might not be your sensor, but something related to the sensor. In order to pinpoint just what the issue is, you will need to do a thorough diagnostic examination. In other words, do not automatically assume that when you see a P0368 code that you need to replace your camshaft sensor.
In many cases, a P0368 is very serious, particularly when your vehicle will not start or your acceleration is jerky and rough. In most instances, a professional technician should handle a P3068 code. If you do not have the specialized equipment to diagnose the problem, your best bet is to consult a trained technician and have him or her solve the issue for you.
Fluid contamination in your vehicle may cause camshaft sensors to malfunction. When the crankshaft sensor malfunctions, some vehicles will store a camshaft position sensor circuit code. If either the camshaft sensor or the crankshaft sensor is malfunctioning, you should probably replace your camshaft and crankshaft sensors as a set.
In some cases, a P0368 will prevent your car from starting. Obviously this is something that you will want to fix right away. But please note that fixing this issue can become very complex and that doing the repairs on your own may involve long hours of labor with expensive diagnostic equipment. Therefore, it is important to do the correct amount of research before you begin to work. Do not hesitate to contact a trained technician to ask questions about this issue.
