Intake Air Temperature Sensor Fault

Hi List,
I started my Land Bruiser (as my kids call it!) and set off for a client
visit. After approx 10 miles I noticed the engine note change for a second
or too and then normalised. A few miles later it did it again but this time
for a minute or so. The engine would become much louder and loose power,
would rev over 1200-1400 rpm. Then it would normalise again and work fine.
The third time it did it the EML came on and I broke into a sweat! The
engine sounded as if the timing was very very advanced and the diesel
detonation was very loud like when you fit a timin gbelt and it is a notch
or two out. Luckily there was a Toyota garage just round the corner from my
client so i pulled in, typically I couldn't get it to go wrong so I left it
with them. few hours later I got a call saying the Air Temp sensor was
faulty and was detecting the air temperature to be minus 40 degrees. It kind
of made sense when he told me the fault. The ECU thought it was at the north
pole. The part required is a T89424-60010 costing =A360.

I just wanted to run this by you guys to find out if anyone else had
experienced this problem and weather I should sleep peacefully?

TIA

"Wouldn't rev over 1200-1400"

Sorry for Typo

OK =96 have I got this, the air temp sensor said -40deg so the ECU went to
enrich the mixture? Surly engine temp would also come into it?

Probably way off =96 spending too long thinking about putting EFI (TBI with a
Megasquirt!) on my 2F.

It seemed more like adjusting the timing rather than adjusting the mixture
(is that possible?). Thats purely my thought not what the mechanic said.
I'll get the details when I pick it up tomorrow

Craig would know if your engine can do that, I suppose some adjustment of
timing could be possible with the latest peizo electric injectors but I
would doubt it would be anything drastic, most of the control time on a
injector is concerned with getting the right quantity of fuel in. I use a
diagnostic system on Perkins diesel engines that cuts each injector out in
turn, quite odd when you first hear it.
Opps just noticed your post was html and I replied, then you replied and
Julian is going to be .
Julian, really trying to eliminate the html, set me email up as per the
instructions, never knew about the conversational view either. I am sure
you will have considered this but what about just bouncing html postings,
easy enough for people to resend?

Hi Malcolm,
I have a grand plan in progress - offendors will be summarily executed
(Reno!!!).
Seriously, am working on a new replacement system that will do lost of fun
and sexy things that should solve all the current problems - first tests
should be mid September so watch this space.

Quick update guys, the Cruiser seems to be running fine since it had a new
air temp sensor. It feels like it is pulling through the range a lot
smoother also. Not sure if that is just my imagination or not. I used Coxon
Toyota in Henley. They are a small family run dealership and have been
around for a while. Their walls are full of plaques for customer awards.
Highly recommended but I doubt they will be local for many of you guys
should you need to go to a dealer. The reason I started using them is
because Octagon Toyota in Reading wouldn't touch an import. I know I could
have had this fault fixed elsewhere but sometimes it is reassuring to see
the readings on the diagnostic equipment and know for sure what the problem
is rather than trial and error.
Anyone know what OBD protocol my import will be running. The connector is
standard but it didn't respond to the common OBD protocols when my local
"Independent" tried to hook up his hand held reader. It would be great to
hook up my laptop and see the various readings in real time.

I believe my LC was doing much the same thing. When cold, it ran great. After warming up, turning off and starting 20 to 30 min later it missed and lost power when taking off from a stop. Mechanic got a temp sensor fault, also seeing that the sensor registered 40 below at all times. They are replacing the sensor now and will let you know if that fixes the problem.

Just a follow up. I had the air intake sensor replaced for $700 and the LC runs like new again. Thanks to Bob's Garage in Westfield, IN.
