I have a 2006 Buick Rendezvous and my check engine light came on. Its been on for a while. I took it to advance auto part and they did a check engine light they told me that my Sensor A was bad. I replace the sensor A, now it was on I took it back they told me I had a code P0455 and P0405. I replace the Fuel Cap and now took it back I only have the P0405, I bought something called Sea Foam Motor Treatment and I still have the check engine light on. Any Advice? Please Help!

P0405 is a egr position low voltage code, would need to be further diagnosed using a factory scan tool such as a tech 2 to determine actual egr position, and if it is an egr valve itself, or the circuit. The 455 is a gross leak in the evap system, most commonly the gas cap not sealing or was left off at one point. The sea foam will not correct your cel problem.
