Bypass kit or replace air injector pump/check Valve

Hi everyone, I have a issue about my air injector pump or the check valve. It puts me on limp mode which we all don’t like due to lost of power. I replace one side (passenger) due to the intrusion of the injector check valve. The driver side are fine, it doesn’t have the intrusion like the passenger side. So I didn’t bother but That thing ain’t cheap though. $275 around there. I thought of replacing the pumps to but when I diagnosed, it’s still operate after researching through YouTube and forum. Plus those 2 are $500 plus each, So I think it’s not the pumps. It’s the valves from what I think. But anyways I replaced it. The limp mode, 4HI blinking, VSC, TRAC control & check engine light went away for a month. It came back on in one morning one the way to work, Which it pissed me off. Almost trade it in. But thought of all the suspension,wheels, tires & the most is the heavy duty leave spring I installed. I don’t thinks it’s worth it for a trade in. They probably ripped me by “oh it’s got a 4 inch lift on it”. So please y’all let me know what think? I wanna know if I get that Bypass. Will it stop the limp mode and all the check light problems or it only last for certain amount of time? I keep on having a thought what the old saying “You get what you pay for”. That make me having seconds thought of not getting the Bypass kit.

 

Why not let toyota fix it for free ?

 

AIP warranty was extended to 10 yrs, 100K miles (possibly150K?) I'd call your dealer although your 10 yrs is almost up. Mileage? Yep ....call dealer.
