This morning I noticed that my check engine light came on, when I got it scanned the following 3 codes pulled up. Other than these codes the truck is driving alright. Earlier today I did notice that it was having trouble getting over 2000RPM. Also the check engine light came on about 6 weeks ago but automatically shut off within 48 hours.

P0014 - "B" Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)

P0016 - Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)

P000B - “B” Camshaft Position Slow Response

Trying to understand these codes are like a foreign language to me so I am hoping you can help with a few questions.

1.A few months ago the truck was in an accident where the front end had to be rebuilt. They had to cut out the frame and side extensions and soldier in new ones. Also they had to replace the radiator. Other than the radiator, I was told the damage was mostly 'cosmetic' and not mechanical. Is there a chance this has to do with the accident?

2. Can I keep on driving it for a few days before taking it to the shop or should I avoid driving it and take it to the shop ASAP? Last thing I want is to cause more damage!

3. Any ideas what can be causing the failures and how much the repairs is going run me?

Thanks for the help!!
