Great video! Hit the highway on the weekend and the engine & VSC lights started flashing with no power loss. Still drove fine but slight howling. Checked for code and it was P0046, watched some ytube videos and sprayed the arm on the turbo cleared the code and it hasn't returned but the howling is still there. My mechanic said it seems like a turbo but the the 2 he had changed on 1kd's where screaming. The weird thing is it still drives like normal. The noise seems to be louder when cold. Any thoughts?

Your turbo actuator is probably stuck hv it changed n it should be fine mine got the same problem m changing the actuator this week 👍

@@georgemickael2854 i decided to change the turbo with a brand new one. After 50,000kms it happened again with no engine light. Just the siren noise.

I got p0046 error on 2008 prado 120 series associated with loss of power. The MAP sensor filter was cracked leaking some oil. Mechanic said replace turbo, I replaced the $60 filter. Seems problem is now solved

Hi The Automotive Technician, Im hoping you might be able to help me, Where do i start i guess at the beginning, I bought a 2009 hilux 3.0l last year with a new MOT on it ran it all year without issue. Went in for its mot and failed badly on emissions. My mechanic ran tests and found all number of issues. Basically i have bought and put in a 2014 engine thats suppose to have done 72000 miles. I have had to refit the original fuel pump injectors, air intake etc to get the wiring loom to work as the new engine had a completely different loom and plugs on all the ancillaries. Got it in fired it up and it smoked the place out at first then cleared out but it had a injector knock and will smoke if you hold it at 3000rpm anything below that it run perfect. We thought it was the injector as the ones from the original engine had done 200000miles. I had them tested and two injectors out the four were bad. so i got a service exchange set of new injectors and put them in, got them coded so all the lights on the dash went out. Started it and it filled the place with smoke again which after letting it run slowly cleared abit so i took it out for a thrash to try and clear it abit which it did but it is still showing the same traits as it did before i got new injectors you rev and hold it at 3000rmp and it smokes like its over fueling and when you rev it the diesel knock is still there. My and my mechanic are loosing the will with it but ive invested so much in it now that it needs to work for me. Thanks In advance Paul Snell

Replaced a cracked filter today as the car was down in power. Made no difference so pulled off the dump pipe and found a broken fin jamming up the turbine.
