    I have a 2007 Tundra Crewmax with 2WD. A couple of weeks ago, I the VSC & CEL came on. After some online search and testing the OBD, I got a code P2442 which calls out it's the Secondary Air Injection Valve stuck open Bank 2.


    After replacement of the Valve, I cleared the CEL and then the I got a code P2237 which is the O2 Sensor Positive current control circuit/open Bank 1 sensor 1 and P2240 which is the O2 Sensor Positive current control circuit/open Bank 2 sensor 1 & Cylinder 8 Misfire. (VSC & CEL still on)


    After replacing both O2 sensors, also replaced all 8 spark plugs, and Coil Pack for cylinder 8 (Last plug on passenger side), the (VSC & CEL still on and Cylinder 8 Misfire still there)


    Today, on 3/3/20, after some more research, I replaced the Gas Cap and clear CEL, still same message but did not drive it yet.


    The only thing left to replace from research is the Fuel injectors. Can anyone help me out here???

    Would the AIP bypass kit be helpful in your case? Sounds like the issue.

    Did you replace all 4 O2 sensors? I’ve had codes call out the wrong bank before. I know you mentioned you cleared codes after the pump replacement, but did you clear them the second time?

    I would not replace fuel injectors. Toyota’s fuel injectors don’t go bad. If they did you would have other issues.

    Thanks for the comments.
    Update: Over the weekend, I unplug the negative terminal from the battery for a couple hours and now the VSC and Track control light turned off. Now, only the Check Engine is flashing and engine still sounds crappy and still stutters above 40MPH but if accelerate to around 50MPH, it goes. Any thoughts?

    A flashing CEL is the ECU trying to tell the driver to let off the throttle!!!

    Why?

    Way too much un-burnt fuel is passing thru to the cats, it will shorten their life considerably if CEL keeps flashing.

    As others stated, AIP bypass is necessary yet I think it has more ignition issues to cause the CEL to flash. Even though new coils and plugs went in, one or more are missing. Check the CEL codes again - got to stop the miss.
