best is to get a complex car serviced, by someone that can work complex turbo diesels,

P0046 fault code for toyota fortuner


Diagnostic Test Code (DTC) P0046 is defined by SAE J2012 as "Turbocharger/Supercharger Boost Control "A" Circuit Range/Performance".

Please note that this is a CIRCUIT code. This means that the electrical circuit for your boost control is not operating within its designed "window of operation". The circuit must be properly diagnosed to determine the actual CAUSE of this code setting.

Specific vehicle/circuit information, as well as proper testing equipment and techniques will be required.

Losing boost!! I have a 1993 mazda rx7 13b twin turbo with the stock turbos. When i punch it my boost goes up to about 10psi. But bleeds off and i can head it blowing out. Was thinking it was blow off...


Have you checked all the tubing cuplings? When mine was doing that i had a cupling that would keep sliding off just enuff that it was letting out air and loosing me boost.

I would change the coolant temp sensor if it's not too expensive at the auto parst store, or unplug it and drive around to see if the boost works normally. Be sure to clear the codes that may light up on your dashboard after either solution.

Im not an expert by any means but it sounds like you are running out of fuel in the combustion chamber (or lean) and setting off the cars knock sensor. It seems to me there are several fuel pumps available on ebay eluding to the fact that they were a weak component. be extremely careful "pinging" is extremely BAD for the pistons and block. keep out of hard boost until you solve issue.

Noise in '93 GT Starlet engine


Probably just the drivebelt/tensioner/waterpump thats giving up, almost never the crank, but do get it fixed asap...;)
(If the drivebelt breaks while running it will destroy the engine!)
