One week old. 170,000 miles. started with sticky speedometer and odometer. followed by VSC light and sign. Now check engine light. VVT circuit range / performance fault P1346. Would changing solenoid actuator help?

it is normal. car is designed to do this when engine is cold. it called open loop. when it warms up it is called closed loop.

P0420 is "catalyst system below efficiency". It means that the car thinks a catalytic converter is bad. It could be that the cat is failing, but it also may be that the secondary oxygen sensor (behind the cat, used as a comparator to determine the health of the cat) is failing. As that part is about 10% of the cost of a new catalyst, I'd replace it first, have the code cleared, and see if it comes back.

First check and make sure your gas cap is tight, if this does not resolve the problem read below.
A vacuum hose has become disconnected, more than likely due to having your air filter replaced. The VSC and Check engine light typically don't come on until after 150-200 miles after the vacuum hose was pulled out.
The fix: on the right-hand-side of the engine compartment behind the big plastic housing that holds the air filter you will find a black rubber hose that is not connected to anything. Squeeze the finger clamp on the hose and slide the hose back onto the half inch nipple on the back of the air filter's plastic housing.
In order for the VSC and Check engine light to be turned off, you will need to open the fuse box, right-side of the engine compartment, and pull the 20 amp EFI fuse for 10 seconds. This will reset the system. The fuse location is marked on the lid of the fuse box, also I believe the EFI fuse is the only 20 amp fuse
. This will help. Thanks, please keep updated. please do rate
the solution positively .thank you for using fixya
