Code p0016 stays

What exactly does this 'light' look like? Any light, especially if it is Yellow or red, needs to be investigated as soon as you can. The shape and colour of the light give a clue as to what the problem could be. Code $7E8 is a 'Sub menu' code on the scanner you used. When this appears scroll down to it then select it. This should bring up another code usually starting with a P then four numbers. Comment below with that code and I'll try to help you more.

Code P0016 indicates there is a problem with the VCT (Variable Camshaft Timing) in your engine, and the timing between the crankshaft and camshafts are possibly misaligned. It could be due to a number of reasons, including:

• Stretched timing chain

• Timing chain has jumped teeth

• Faulty timing chain tensioner(s)

• Crankshaft reluctor ring damage

• Wiring and/or connection problems

Are there any other codes in addition to the P0016 or is that it? If it's the only code, that's a good start.

The first thing to do will be to have the engine timing checked. If it's still timed properly, the camshaft and crankshaft sensors should be inspected and tested next, as well as their wiring and connections to ensure they're clean, connected firmly, and have no breaks or corrosion.

Codes are OBDll and are available online free.

There could be many causes other than straight forward replacing the sensor.
P0016 Causes

• Frayed cam sensor wiring
• Frayed crank sensor wiring
• Faulty timing belt/chain
• Defective tone ring
• Faulty cam sensor
• Faulty crank sensor
• Faulty ECM

Hope these help

P0442 is the evap system. P0016 is Crankshaft-Camshaft Timing Misalignment Bank 1 Sensor 1.
P0344 and 340 is the CPS circuit. You probably have BCM faults as well. I would troubleshoot the camshaft sensor circuit first and replace the sensor if it does not test within specs.
I hope this helps.

This is what the p0016 code means.
