About 3 weeks ago I posted that my sons 99 Sonata 2.4L would intermittingly
cut off and restart in a few minutes. There were no DTCs. Then one day it
would not restart and he had it towed into a independent shop. Their
diagnosis was that the valve cover was leaking oil into the spark plugs
and
had shorted out the plugs and the coil packs. I told him that I didn't
think
they knew what they were doing, but they had him over a barrel. They ended
up charging almost $800 dollars to replace the valve cover gasket, 2
coils,
4 plugs and wires. Much to my surprise, he was able to drive it home after
with no more work required. But it only lasted about 3 weeks and it died
again on the road. He had it towed to the same shop thinking that they
would
stand behind their work. Of course the next day they come up wanting
another
$700 for fixing it this time. Now they want to replace the crank sensor
and
the output speed sensor. He asked them if it would be OK if he waited till
the next day to let them know what he wanted them to do and they replied
that they had already moved the car out of the shop. He asked how, and
they
said they just started it up and drove it out. He called me and I told him
it was time to cut his losses with these bandits and to lets go get the
car
back . When we got to the shop they wanted $80 (1 hour labor) for
diagnostics to determine the problem. I asked them how it took an hour to
read the DTCs with the scan tool, and hadn't he paid them enough already.
After an lively discussion we agreed to pay them $40 to get the car back.
I read the DTCs and they are
P0335
P0715
P0725
and P0715 (P)
So it looks to me like it needs a new Crank Sensor and a new Input Speed
Sensor. I went back and looked at receipt/work order and it definitely had
output speed sensor on it. I wonder if they were setting him up for a
return
visit for more bucks.
After some cursory research it appears that the speed sensor should be a
piece of cake, but I am concerned that the crank sensor may be more
complicated that I first thought.
Few questions for HyundaiTech.
1) Is it just a coincident that these combination of codes showed up or
does
it mean something more serious?. They appear to be two completely
unrelated
problems. Why would they appear almost simultaneously?
2) Is it normal for the same code (P0715) to show up solid and pending?
3) Any idea why they would want to replace the output speed sensor? I'm
assuming they didn't clear out any codes.
4) I haven't done any real engine work since they did away with the
distributor, do you think I will be getting in over my head to try to
replace the crank sensor?
5) Any comments, hints, shortcuts, got'yahs will be appreciated..
6) Where did they put the location photos in the new format
Hmaservice.com?
I had figured out where they were in the old format, but can't find them
now.
7) I am assuming that there's no timing issues I need to be concerned with
by changing the crank sensor, correct?
