    Check Engine Light, VSC Flashing and Slip Indicator Light on. Truck was sluggish driving. Took it in to the dealership today and informed that the there was water in the Air Injection pump and needed to replace air injection pumps and values, cost $3,149.00. 09 Tundra 171,000 miles. I know the day I started having issues, same day filled up with gas at BP station, any chance just got some bad gas?
    Anyone had similar issues? Scheduled to take to local mechanic to get 2nd opinion.

    I just got a scanner to reset it. But mine did not get sluggish. Eventually it may have fixed itself after a few thousand miles.

    My 2010 had the P2040 code, I could reset it with my OBD 2 device but it came back immediately, dealer wanted $2300 to fix it, ordered the Hewitt Tech gen 1 kit with block off plates and installed it in a couple hours, has not had a problem since. My truck only had 65k miles and was 5 weeks out of the 10 year warranty, Toyota said too bad nothing we can do for you.

    Mine has been bypassed since 2011. My home version costs about $40.

    You do need to check to make sure the dealer has not re flashed the air injection pump system ECU.

    Purchased Gen II Bypass Kit Hewitt-Tech, $450.00, local mechanic installed for $115.00 today. Problem solved, Truck runs great, no more warning lights. Total to fix $550.00, will take that over spending $3,000 at the dealership.

    Thanks for everyone help on this forum regarding this issue

    Just wanted to add, local mechanic did a complete diagnostic test after I told him the diagnostic test results from the Toyota dealership P2440 code(Water in AIJ pumps values stuck open ). Local mechanic informed me after his diagnostic test, no sign of water intrusion, values and pumps operated normally, problem possibly in wiring or ECM driver but needed Toyota factory scan tool software to pin point the problem.
    Told me Toyota did not do a complete diagnostic to check to see if the values and pumps were operating normally, just read the engine code, P2240, and went by recommendations to replace Air Pump Inlet, Air Pump Assembly and Emission Control Value Set.
