one code read Tb requires adaptation. I assume when you remove it to complete the CCV replacement, it needs a reset to communicate with the engine and trans. Both went into failsafe mode after. The car would only run at idle. I took it out, gave it a good cleaning with a rag and cleaner and re installed. The adaptation procedure is nothing mote then ignition on, gas pedal to floor five seconds, release and turn off, wait 2 minutes then start. it worked fine.
