P0349 is a diagnostic trouble code (DTC) for "Camshaft Position Sensor A Circuit Intermittent (Bank 2)". 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. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
Your vehicle’s PCM has found an improper wave form or voltage reading from the camshaft circuit A in engine bank 2.
The camshaft position sensor works with the notches, or teeth, on your camshaft to regulate ignition timing and fuel delivery. This code means that there is a deviation that is placing your camshaft in a bad position. When this happens, your Check Engine Light will come on, and a P0249 code will be stored. Some vehicles will do this on the first occurrence, but others will require at least three occurrences before activating the Check Engine Light. The code will still be stored, but the light will not come on.
Any deviation from the vehicle manufacturer’s specific value can trigger a P0249 code. This code indicates that your camshaft is not in the right position.
You might not notice any symptoms early on. If the condition is not corrected, though, you may notice:
An electromagnetic sensor (the camshaft sensor) works with a gear on the end of the camshaft to regulate your engine timing. When the timing is off, a P0249 code will be stored, and then it is up to your mechanic to diagnose the code properly. To do this, he or she will use a scanner, ohmmeter, and also perhaps an oscilloscope.
Your mechanic will:
Sometimes, mechanics replace the PCM before considering other reasons for the P0249 code. The reality is that the problem is hardly ever in the PCM – it very seldom fails.
How badly do you want to get to work? If your car engine doesn’t start, then that could be very serious, not in terms of your safety, but in terms of your getting where you want to be when you want to be there. Stuttering and stalling might not be a huge issue, unless you’re on the freeway, and then it could be fairly serious. This problem isn’t going to get any better, so although you don’t exactly have to panic and get to a garage immediately, it would probably be a good idea to get the problem taken care of as soon as you can.
A qualified mechanic can replace or repair any damaged wiring that is causing the PCM to record a P0249 code. If the PCM itself is faulty (which is unlikely), then that can also be repaired or replaced.
Your vehicle contains numerous sensors, and yards and yards of wiring. There can be problems anywhere in the system. Diagnostics can be complex and time-consuming. A P0249 code may not be something that can be diagnosed quickly or easily. Mechanics need time to find out what is wrong and get your vehicle back into proper working order.
