Calibrated the pump? How did you do this??

Using my diagnostic tool, in this case Snap-on. I selected Toyota (something I rarely have to do).

Any decent workshop should be able to do this

doing a tune has no effect on if the scv can be calibrated or not, its because the pump needs to be done first.

So to go a bit further if you replace injectors you need to calibrate injectors, then the pump then the scv in that order.

Also if the Defender 2.4 is not bringing up a fault code and only symptoms of a failing scv you can often replace it without doing a calibrate.

at $130 for a no brand one its the same price or similar to a DENSO so why bother.

If you get a actual Denso boxed one it has 2 locating pins in it that are supposed to assist in lining it up.

I have techstream and a lot of experience with the brand. The only functions available are to initialise the supply pump and code the injectors. SCV problems were common in mid to late 2000s but updated parts largely resolved this. Contamination and non-genuine parts are the only problems we see these vehicles.

If the toyota software doesn't offer any calibration, I'd be keen to see what snap-on provides.

I dunno, brothers 200 series cruiser (which is only 2 years old) was in my workshop one day, its always rattled badly even after the dealership said "its within spec" I simply went through the menu saw pump calibration, went through the process, you sit there with the engine running bringing the throttle upto I think 1500, then back to idle, you keep doing that until the engine light stops flashing, i think there was even a message on the display telling you its done. After that its didnt rattle, I really didnt think anymore about it as I dont work on them.

maybe the toyota land cruiser forum has better answers
