turbo boost pressure sensor

[ron grace]

Hi I have a turbo pressure sensor fault showing on my dashboard.
What could cause it? as there are no sensors or wires on the turbo unit

Regards .........Ron Grace.

Need more information:
Surf or 4Runner.
Year.
engine size.
colour.
tyres.
lift.
Wife/girlfriends name.






OK, maybe not the last four, but the first three would help.

If it's a 2.4 the sensor is next to the air filter housing on the side facing the bulkhead.

Thanks for that Gary we found the fault one of the pipes was not connected.
Nigel sent me a drawing of that area.
Its "D" day next week the surf will be on the road, I need to try it out as this one had a cylinder head problem.
We fitted a new head radiator flushed out blocked heater pipes etc etc. So I just hope we have sorted outn the problem and every thing works o.k.

good thread terry.
an extra 100 km from a tank would be an awesome gain

Interesting thread that. My soarer boosts at around 9-10psi and uses a 1 bar map sensor. I may try see if it will fit the surf and improve things a little.
When we go to hyper boost settings on the soarers, it's common to fit the map sensor from a supra 'cos it has a 3 bar sensor, allowing more accurate metering above the standard 1 bar limit.

To all who helped, its worked.

I have a 1993 Toyota surf manual 2.4td 2L-TE engine.
Well a lot happened in the past months. My surf was still over heating after changing the head, radiator, thermo stats, etc etc.
So we changed the engine for a import 30.000mls + or - ? after lots of work and swapping parts from the orig engine we got it going. Took it for steady test runs until we were happy it hasn't overheated.
But first thing on a morning on start up, there's smoke everwhere, but once warmed up o.k. We took the injectors from the orig engine which had been overhauled, incase these were leaking. In doing so we noticed the washers, both the larger brass looking one and the smaller s/steel were missing so we put them in with the other injectors.
Unfortunately its still very smokey on first thing start up. My brother who is the mechanic thinks it might be the timing of the fuel pump, but he's not sure. What do you all think and how do we set it up?

What fuel consumption should I be getting with the terbo working.

And where can I get roof bars my Toyota hilux SURF 2.4TD MANUAL 2L-TE engine.
I'm also after a wheel and tyre to use as a spare, I have 4x goodrich all terrain t/a 30/10.5 r15 alloy wheels and my spare is a is a bridgestone desert dueler 215/sr15 so I think its best to change the spare. But I can't get one. Has anybody got a 30/19.5r15? and roof bars for a 1992-3 surf with out gutters. We are off to the Lakes this weekend for a final test run, so it will be ready to ship over to SOUTH AFRICA. So I'm trying to get everything sorted before the big day in Feb 2009.
I'm asking a lot sorry. Please help.
Regards .........Ron Grace.
p/s i'm sure Ive missed something?.........Just joking.

That’s a very interesting thread, so I assume that blocking off the sensor pipe is still allowing the turbo to do its bit but not giving it the extra fuel, therefore being more efficient. But from previous experience on petrol cars (Saab 900 turbo) if you boost without the fuel then this causes the turbo to overheat, is this the same with diesels or am I missing the point.??

I don't think it would have any effect on the turbo. I may be wrong but can't think of a logical reason why it would.

It could be fun to hook up a solenoid on the sensor pipe to the kick-down cable so it only boosted when you stamped on it.....

Recheck the timing, but mostly likely to be the glowplug fuse/relay or the plugs themselves are knackered

Mid 20s MPG

Halfords. Ask for a 93 4runner

Do you mean 30/9.5/15 or 31/10.15/15?

Already got a digital pressure sensor with two adjustable, 12 volt outputs connected so it would be quite easy to do for me but I'm worried about the turbo, as i said i have been down this rout before with increasing the boost on a turbo, without increasing the fuel, the temperature of the turbo went off the scale on and industrial temperature sensor, so I'm a little wary, not sure if diesels are any different.

boost sensor

Having read the Oz surf forum, I've fitted an isolating valve between the in-line filter and the boost sensor. the valve is temporarily fixed to the drivers grab handle for easy access if i do need the power.
The surf runs pretty much like it did when a pipe fell off a few months ago.
Acceleration is still ok up to about 25 mph but is slower than normal up to my usual top speed of about 60 for this journey. All in all though, the drive is pretty good.
I've also fitted a performance air filter right on the turbo intake and a catch pot it the breather line to try and lean out the mixture
The catch pot has been on for a week now and, although there is a little bit of grime in it, I'm not seeing the volume of oil I expected to see after inspecting the inside of the turbo inlet pipe.
before I fitted the sensor valve, the performance filter seemed to make a slight difference in power but not sure about any improvement in mpg. I was being quite heavy with my right foot all week but my mpg was exactly the same.
Anyway, I keep a close check on my weekly mpg so I'll write another post if there are any improvements on the current 21.5 - or disasters!
