2000 Hyndai - Sonata (Check Engine light is on ...)

All,

I have Hyundai- Sonata of year 2000. For last 2 days suddenly my 'Check
Engine' orange light is on and vehicle is getting jerk (If I am raising
speed above 50 MPH) and also when it's become slow. During start-up
from stop signal, there is some jerk in vehicle. I took to mechanic
today and told about the issue. The mechanic told need to replace spark
plug and wires boc'z it's not been change since the vehicle is bought
in year 2000. To change above mechanic quoted $160.00.

I am sure somebody might already had above situation, please let me
know is there any way to fix it with your help?

Thanks in advance,

MaC

 

Replacing the spark plugs and wires may be a good idea based on your
vehicle's age and mileage, but you've presented no evidence that's the
cause of your check engine lamp. When the mechanic looked at the car,
what diagnostic trouble codes were stored in the engine and transmission
computers?

 

The experience I had with this check engine light problem. In my case,
it turned out to be an R/R sensor.

Symptoms included after the check engine light came on...a jerk and the
car acting as if it couldn't get out of 3rd gear.

I don't know what a R/R sensor is or does, but after $300 the car runs
fine.

 

Well, I've never heard of an R/R sensor, either. Based on the symptoms, I
suspect what they've replaced is either the input or output speed sensor
on the transmission. These provide the transmission computer (TCM) with
the important information it needs to shift properly. When the TCM
figures out that it's not seeing the proper information, it puts the
transmission in third gear and leaves it there.

As far as the plugs and wires, if you've got a 4 cylinder, that sounds
about right for quality parts.

If you've got a V6, it's way too low. On the V6, you should put in 6
platinum plugs, and a not-cheap high quality wire set. The intake plenum
needs to be removed to do this job, so it'll have a high labor cost as
well.

 

R/R sensor - means they removed and replaced a sensor, should have a part
number in the parts column.
