P0500, I already wrote about it in a few of my previous posts.

P1346 is a pretty vague code, it is likely not just a bad sensor. On paper it states that the Crankshaft and Camshaft timing is misaligned, aka the belt jumped a tooth, but there is a number of other things to check before throwing parts on problems. Start by taking the timing cover off and checking that all the timing marks align properly, then check the VVT-i solenoids and their strainers, here is how to do it. If that won't help, try flipping camshaft sensors for Bank 1 and Bank 2 around, I believe they are the same, see if the code will switch, if so, then it is the sensor at fault, if not, it could be caused by the VVT-i actuator.

As I wrote before, Code 21 indicates a Solar Sensor malfunction, which can appear at random in the dark environment, so in this particular case, it can safely be ignored, unless you have specific issues with it.

What do you mean by entering the info in the diag tool?
Did your scan tool pull up any codes or just written descriptions? For this generation, I believe they still had two-digit codes for ABS systems.

All that likely means an issue with the ABS Actuator unit under the hood, or with the wiring to it. Check the wiring first, below are the pins that I believe need to be checked, then measure the resistance across those pins to Ground to test the resistance of the Solenoids in the Actuator, if there is none, you will either have to take the actuator apart and fix the solenoid, or replace the whole unit.



Hope this helps and best of luck!
