Multiple Codes (hyundai) / misfire, crank shaft, catalytic Sign In

I brought my 2003 Hyundai Sonata (140,000 miles), 2.4 cylinder, into the shop because my car lost power while driving. The check engine light came on a couple weeks prior.

The car started back up the next morning but lost power again after 5 miles. The mechanic says that I have misfires on all cylinders, a crankshaft position sensor error, and a catalytic converter error.

Can the bad spark plugs, causing the cylinder misfires, also cause the other two codes or vice versa? The car is barely worth $2200 and I'm not sure I want to fix it.

Do you have the code numbers? If not, have it scanned and post the numbers here.

Bad spark plugs won't cause a crankshaft position sensor error code. A failing or faulty crankshaft position sensor can cause stalling, rough running engine, no starts, and misfire codes. If you go after the crank sensor, you might as well do the timing belt and water pump.

Wouldn't worry too much about the cat code till you get the other problems fixed first.

Re: Multiple Codes (hyundai) / misfire, crank shaft, catalytic Sign In

What you could do is shop around for some estimates from other shops in your area. That will give you a general idea. That quote probably sounds pretty close to what something like that would normally cost to have repaired.

Hard to say if the car is worth fixing. Do you like it? Does it met your needs? As long as the rest of the vehicle such as the brakes, body, steering, tires, etc. are in good shape you might be able to get more years and miles out of it. Dropping less than a couple of grand into it would be cheaper than a car payment. If your thinking of the vehicle as an investment, forget that. You'd be lucky to buy a good used car in decent shape for less than 5K.

Plus that 5k car would have enough miles on it that it would probably need a timing belt too.

Re: Multiple Codes (hyundai) / misfire, crank shaft, catalytic Sign In

I don't think I want to spend the $1400 to do all this work on a car barely worth 2K. Is it even worth it for me to replace the spark plugs and see if this is the problem OR is it pretty likely that it's the crank shaft position sensor?

I know it's hard to say but trying to decide if it is worth any work at all right now. I'm willing to spend $250 but not 1500 and it seems it might be all or nothing.

Maintenance costs money............

The value of the car is really not part of the equation. No matter what you drive you are going to spend probably $1000 -$2000 a year to drive it, whether that be in payments or in repairs. What you need to actually look at is the condition of the rest of the car and will it hold together without large repairs for the foreseeable future. What you are looking at right now is mainly expected maintenance.

Thanks Hammertime - you see the codes now so I am guess that your response means I need to do all right now of it if I want to keep driving the car. Is that accurate?

No, what I am saying is don't base your decision solely on the value of the car. Base it on the decision of what future repairs might be and that is done by analyzing the condition of the rest of the car..

Re: Multiple Codes (hyundai) / misfire, crank shaft, catalytic Sign In

wildonion: Not sure how you are pricing your own car as it sits with the repairs needed?


What would you buy and what kind of $$ are you willing or able to spend on another? Do the math that suits you as if you didn't have a car at all. Would you buy this car knowing what it needs + some surprises? When older I personally dismiss listed book valuations but rather check them out hard to at least rule out a hidden nightmare car.


Not many folks get away free for transportation. IMO the cost of the repairs if this car is excellent in general you are unlikely to find something used on the lower price end that doesn't need as much also.


True, it does help to know when to give up as you usually will not capture the expense at some point. Cars/transportation is costly, budget it in,

Re: Multiple Codes (hyundai) / misfire, crank shaft, catalytic Sign In

Thanks Tom - I don't minding paying for the privilege to own a car but I guess I don't quite know when it is too much.

Someone else mentioned 1K - 2K per year on a car unless you have a car payment and then you're paying anyway.

I've put in a new battery and alternator, as well as repaired the CV joints and replaced the tires. I was hoping to have a little break before spending any more money but I guess that's not the case for now. :) Thanks again.

As long as your engine and transmission are sound, the car isn't rusted out and you don't hate the car, it's worth doing some maintenance to.

Re: Multiple Codes (hyundai) / misfire, crank shaft, catalytic Sign In

So spark plugs were replaced and the misfire and crankshaft position sensor came back.

The quote for the timing belt, water pump, sensor replacement includes 6 hours of labor at $95/hour. I was told by a friend mechanic from another state that the labor should not be applied per part because the water pump and belt have to come off anyway to do the sensor. They told me the job should take around 3.5 hours so I should not be double charged on the labor. Does this make sense?

Re: Multiple Codes (hyundai) / misfire, crank shaft, catalytic Sign In

Understand your VALID point. Not sure how to suggest approaching this for you. I'm in a rust belt and the dumbest things can take ages more than any listed time which about coincides with when cars come off warranty.


Sooooo, I never used time books. If it took too long I had good faith with people that it was a challenge and equally if something goes so fast. BUT mind you I worked alone so that's that and long done with it.


IDK - ask for a printout of the estimate or get quotes on the work you need as one lump price for all things needed or however you'd like to see it,

Re: Multiple Codes (hyundai) / misfire, crank shaft, catalytic Sign In

You do not have to remove the water pump to replace a crank sensor but the timing belt and sensor overlap so there should be a blend of times a little higher than either one alone.
