If you did not have "interfering "valves, you could take a compression test.
Call a Kia dealership and ask either the Parts or Service department if your car has interfering or non-interfering valves. You need to know. Remember, dealerships must stay in business by selling your their work.
Call an car parts store and ask the same question.
Solution #1) If your can has non-interfering valve, you could pull off the valve cover, and have a helper crank the engine and see if all the valves are moving smoothly up and down and have the same travel (one or more valves are not moving only part--way up & down).
Your valves do not have a lot of "travel" up and down anyway, so you will need to watch them most carefully.
Solution # 2) If your car has non-interfering valves, you pull out the spark plugs and press or screw in a compression gauge to each spark plug hole one at a time and check your compression. You'll need a helper to "crank" the engine while you do this.
Burnt or bent valves will give you no compression on the cylinder with the damaged valve.

If you have interfering valves, you must not do ANY of the above, or you can ruin your engine, as the valves will hit the pistons and destroy them.
In that case, you only option is to remove the cylinder head and have the problem repaired.

I have bad news for you
p0604 is a transmission control module

check the connection at the transmission control module if there are no connection issues than you will need to replace the transmission controll module "tcm" there is no other test for that code.

My 2003 kia spectra jumped time, It don't sound like rods are bent! Is it worth trying to fix?

If it jumped the timing. more then likely it would bend the valves first before a rod. it is worth fixing if all it needs is a new timing chain/ belt and put new gears on also. as long as nothing internal happened it will be fine.

I have a 2003 kia spectra 2.8 and the timing belt broke would the pistons have hit the valves

No they don't . Mine broke on my 2001 sportage and didn't do any damage. This is due to the fact that the engine is called a "non-interference" motor. At no time can the valve hit a piston (in theory) because the valve travel is not enough to ever hit the piston. :) Hope this helps, James Booth

Is the 2003 Kia Sephia engine 0 tolerence, will the valve be bent if the timing belt breaks?

The timing belt should be replaced to avoid the possibility of bent valves if the belt fails. This is normally performed as preventative maintenance when the vehicle has approximately 100,000 miles. However, to reassure Kia owners, I drove my own 2003 Kia Spectra 170,000 miles without performing this maintenance so I can attest to the durability of the factory belt.

It is a gamble to attempt to go beyond the normal service life of the timing belt.

My 2003 kia spectra stalls

It might have a partially blocked fuel line or ait intake supply.
  • Try to check your fuel filter.
  • The seive on the fuel pump.
  • The fuel injectors might be dirty.
  • The air cleaner might be clogged
or the fuel sensor might be malfunctioning.
Try to check the compression, it might be loosing compression when you demand the engine to move the vehicle.
