2010 4lo, VSC, engine lights

4Lo lights just started flashing, along with engine check light and amber Svc light, while I was driving…. Just on a dry city road…nothing out of ordinary. I’ve never had a problem with this truck. So I’m taking it to a mechanic, but I’m afraid of getting taken advantage of. Any info that I could have prior to drop off would be very helpful. Thank you.

 

Hi , it must be the secondary air injection sensor

 

If you have a 4.7 engine is easy to fix , but with the 5.7 is a little bit more difficult

 

Check your battery and make sure your ground points are good. Had this happen with a outgoing battery.

 

This is a very cool table. Thank you for posting. Gives me some reference!
