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.
