1993 Hilux Surf 2.4 Td Poorly Engine ?

Recommended Posts

hi all just want to know if anyone has had same trouble as i am having with my surf. i just bought my car from a dealer 2 months ago and so far i have only had it for 8 days when i first got it it had a water leak and Oil leak and wont pull up hills,the Oil and water leak have been rectified,but she still wont go up hills i told dealer that i am not happy with performance and he has told me that this is how they are.it has had a new head fitted and i have done the obvious filter replacements but the problem remains. when on the flat or downhill she goes like a train but show her a climb and she drops speed as if i am breaking instead of accelerating. if i try from a standing start i get to 20 mph flat out until the hill levels off and away go.been to lucas and he said it is a sensor somewhere possibly electronic fuel pump and told me to take it to toyota dealer for computer diagnostic, when i rang dealer they say cos it is an import they cant get a reading and would not be able to tell what the fault is.the turbo is fine no engine management light on pulling my hair out not sure what to try next please make my christmas a happy one and see if anyone can help me with this issue

many thanks in advance

have a compression test done on the cylinders , change the auto fluid .

check for error codes yourself using the diagnostics plug , rear of bulkhead near fuel filter , join te1 and e1 with a paperclip and then turn on the ignition , and count the flashes from the dash clocks.

the place who sold you it is talking rubbish , my 3.0 td would pull a 2 tonne truck up hill with little effort.

Check that the short rubber pipe, circled in green in the photo, is attatched, if it's not you will have no turbo boost and the performance will be how you describe.

The rubber pipe can often get Oil on it , swell and fall off.

p.s. the part in the yellow circle is the boost pressure sensor. (for future reference) ;)

Any other problems, give me a shout.

i have checked pipe and it is attached been to an import specialist who said the turbo is not working i have done the paper clip diagnosis and got 4 flashes which indicates coolant temp sensor i cant see this making a difference to the engine performance or would it. is it possible it could be the turbo boost pressure sensor and not the turbo. specialist connected a turbo boost guage to turbo and nothing registered when he drove car. would the result be same if turbo sensor was knackered instead of the turbo itself

could be in limp mode due to coolant temp sensor failure ??? probably not but just possibly .try an ecu reset - take the earth off both batteries ( if you have 2 fitted ) , press the brake once or twice to get rid of any 12 volt power, wait for 10 minutes then re connect .

done ecu reset as suggested still no different . the green light on dash that comes on for turbo when driving is not coming on does this mean turbo is knacked??? it comes on when i turn key as do all other warning lights so i know it is working . starting to fear worst that turbo needs replacing. not getting much help from dealer i got surf from he still insists that they are slow on hills but i know from experience of my parents identical model they are not

It's most likely the boost pressure sensor. Ask you 'friendly'dealer if you can try one from his other 2.4 Surfs to make sure.

There isn't much to go wrong with a turbo, is just and impeller spinning on a bearing, thats spun by exhaust gasses. If the bearing fails, or the impeller gets damaged, the turbo will sound like a handfull of nails in a tin can being shaken about!

The green turbo light should come on from around 1900rpm onwards, and go out when you release the gas pedal.

at last.............. figured out why my surf was slow on hills thanx to vince w for sending me a photo of turbo boost pressure sensor i realised that the rubber pipe from my sensor did not go to the same place as the one on the pic so parked at side of my parents surf and made a few changes to the location of some of the pipes and job done..... she goes like the wind, and turbo light on dash comes on now,but most of all the best thing about this repair was the cost... it was free.........thanx again vince w i would have been well lost without that pic

i done better than telling dealer he was talking b*ll@x, i have had a mechanic friend of mine draw me up a bill for about £100. sending a copy to dealer who has said he will send me cheque for the repair cost. i told dealer it was turbo sensor and reset of ecu.he can pay for all the fuel i have paid out for to run around to try and get it fixed

Sorry for reviving this old thread but I may have trouble with my Turbo as well. I've got the same Hilux model as above with similar symptoms (poor performance/fuel consumption).

I have a question for Vince: In your pictures of the vacuum system of the Turbo I noticed a T-piece in the connection between the boost sensor and that little tube (encircled green). This T-piece plus vacuum hose in absent in my engine. Can you tell me where the rubber hose, going towards the fuel filter, is connected to?

Much appreciated!

It's connected to a boost gauge, has been fitted by the owner.

I dont mean to bore with this subject, but have just taken ownership of 93 2.4 and likewise struggle uphill. so thought i'd check my setup, finding the smaller hose to turbo sensor not connected, in fact it had been clipped up in fresh air and not even blanked off!

(I thought said hose came from a 1 way valve at the top, but i can take it off and blow thru either end, so maybe its a moisture trap!?)

Incidently, my turbo light only iluminates before ignition. have yet to give trial run after connecting hose back to sensor.

Could this open hose actually have an affect on the turbo?

Edit:- My conclusion is yes! This baby now flies, Turbo light on @ under 2k revs + big reduction of black exhaust smoke.

Hi guys new member here, I'm having what sounds like a very similar problem, and when looking under my hood i see that the small pipe that runs to the turbo pressure sensor is not connected, if one of you buys could upload a picture showing how it fits that would be awesome.

Cheers
