## Customer Reviews

### ⭐⭐⭐⭐⭐ Did the trick.
*by A***R on September 30, 2020*

Perfect fix! Erased the p2440 code on our 08 Sequoia. The pumps can also be problematic (apparently they get water in them) I took ours out and inspected them but they looked dry and okay. This part did the trick but it was an all day procedure. You have to take off the intake and a thousand vacuum lines to get at it. Also it is in a tough spot so I watched a video on YouTube for tips which helped a lot. I am no mechanic but the dealer wants 3k-4K to do this so I took a chance

### ⭐⭐⭐⭐⭐ Save money
*by A***R on October 4, 2023*

2008 Toyota Sequoia with a P2440 error code. Dealer wanted $4000 for the repair. Order the Dorman 911-643 and did the job myself, saved me a lot of money. Note: It is a semi difficult job to do for a weekend warrior even with the right tools. Local mechanic quote was $800 for labor.

### ⭐ 2008 Toyota Tundra 5.7L
*by K***R on May 31, 2022*

This product did not work for my 2008 Toyota Tundra with the 5.7L. Spent 4 hours changing the part because codes were indicating secondary pumps and control valves were bad. Truck drove alright, but check engine light was on and mileage was pretty bad. After changing the secondary valve unit, truck went into limp mode with 4LO, traction control, check engine, and VSC off lights on or flashing. Had to remove the control valve assembly and buy one from Toyota. Installed and running fine.
