Code 0093 Fuel Leak

[Loobs]

Hi there,

My dads 2003 XT3 came to a halt on Sunday am with the code 0093 Major Fuel leak. As there isn't a fuel leak present, I mad an educated guess that it mat be an SCV fault. We ordered a set which were fitted today but it only them ran for about half a mile before cutting out and then takes ages to start and cuts out after a short distance. He's decided it has to go which is a shame.

It had been running erratically previously in that it would race on idle.

Any ideas welcome.

try changing the fuel filter first

I changed the fuel filter as part of the service about 2000 miles ago. It was fine after that. Would the filter be u/s already? I've used the same filters on mine with no problems.

I've seen on another thread about software updates after changing the valves???

injectors are a likely cause of your problem

Probable causes:

1. SCV's did you fit modified Toyota parts 04221-27012 or a set of unmodified aftermarket.

2. Failed injector seal/s order and fit a complete new set ( most important ones are the nozzle tip washers )

3. A fuel leak in the high pressure side, remember part of this is inside the rocker cover so might be hidden.

4. A faulty or sticking injector remove them and take to a diesel specialist for testing.

5. Worst case the high pressure pump is faulty.

Thanks for all of the info. Much appreciated.

Dad bought a new fuel filter on Friday from Toyota, I installed it yesterday and that seems to have cleared the fuel problem. We took it for a run of over a mile last night. He now has the P0105 fault, EML came on after about 200M initially. I cleared it and then it came on when he revved it. He will head to toyota again today to get a MAF sensor.

Get a diagnose and check values one all 4 injectors.. my bet is one or more is about to die.. just had same error.. pulled out my scv and jump tested them, all working. Turned out to be major error on injector 4. Had to get a new one. Error code gone, car is like new!

It's been running fine since the fule filter has been changed. He went and bought a MAF sensor but the EML hasn't come on since he got it. I've told him to keep it in the glovebox anyway seeing as it seems to have scared the other one into working!

He has decided to trade it in now as he wants some better reliability, both ofthem are in their '70s and grinding to a halt on a busy road didn't cut it in his eyes. A shame cos it's a nice car.
