My Sonata with 2.4 DHOC engine stalls after about 15 miles from a cold
start. I then have to wait 2 - 3 minutes to restart so I can go another
mile or two. THe car has 53000 miles and I'm the 2nd owner, so I'm out of
warrantee. Just had timing belt replaced in August. Due to the computer
code, Pep Boys replace the Cam Position Sensor, however the plug to the
sensor was bad so they rigged it for the time being. The problem did not
go away - and now Pep Boys tells me I need a new plug but the only way that
comes is in a wire harness at $1150.00 before labor charges. Is there any
way around this as I can see harness and labor charges exceeding what I
originally paid for the car. Thanks in advance for any help or
suggestions.

The symptoms you describe are exactly consistent with one of the camshafts
being timed a tooth or two off. This will cause stalling in the manner
you describe as well as the check engine lamp with the trouble code you
report.

If the problem were with the camshaft sensor or the data it reports to the
ECM, your car should still not stall. You'd experience the trouble code
and check engine lamp you report, but your performance issues should be
limited to a tip-in hesitation on acceleration.

Plug should be very easy to replace/repair by someone with a little bit of
electrical experience. If you can locate one in a junk yard cuth the plug
out & splice it in. If it is a common problem your deler may have a repair
kit
available

Sorry to take so long to say thanks, but here's what happened since I
started. I got the camshaft sensor plug replaced by Hyundai after
finding out they had a kit, also they again replaced the crankshaft
sensor (3rd time in 18 months). Next day after driving 60 miles on one
trip then another 3 miles, the car strands me again. The Hyundai dealer
had to take off the head to find one cracked piston and two badly scored
pistons, and suggested I either get another engine or look at another
car. My suggestion that they may have put the timing belt in wrong did
not go over very well but they gave me an excellent allowance on the car
toward another used (but with 2 years warrantee left) car. I probably
could have sought legal remedies but I still needed a car in the
meantime. I noticed the used car manager did try to jack up the
replacement car price by $2000 higher that his advertised internet
price, which would have made my allowance quite a bit smaller, but we
settled that matter to my satisfaction.
