P2440
"function restriction due to receieved malfucntion value"

Got these fault codes/CEL. Recently installed 034 test pipes. i expected to see O2 sensor related codes after test pipes.. do either of these mean anything to you?

The intake manifolds have vacuum actuated flaps that cause the intake air to tumble to produce ideal airflow for fuel mixture. These are situated between where the SC mates to the top of the intake runners, but before the intake valves. Someone else had this error and there was a faulty vacuum line or something and the dealer had to fix it. Let me dig for the post.

unfortunately, the code is still there. any other ideas? i just installed the test pipes before the code came up. you think the test pipes are TOO free flowing, and the sensors cant read the pulses? i need to fix this asap

they checked that whole system. they said the intake runners are a different system than what i'm throwing codes for. he said its specifically the SAI switching vavles on both sides being stuck open.. but having a really tough time troubleshooting. only option at this point seems to be removing test pipes.. paying for the labor, and then HOPING that the problem goes away.
