Sarah, The Engine Coolant Temperature Sensor on your Kia is located below rad hose driver side by exhaust manifold. May be a good time to flush coolant system when changing sensor.
Check the attached links,instruction and guides, Good luck

Crankshaft position sensor - 2003 Kia Sorento - RepairPal

Here's a link.Here's what it look's like.

expensive item to replace it is situated at the back of the engine just above the sump on the opposite side to the oil pump and is held in by a single bolt if you unscrew this it will just pull out and disconnect from the cable at the clip joint.

first why and how did you tighten the timing belt. if was loose should just replace the timing belt that belt runs the timing.the code po335 is your crank position sensor and it is coming up the engine is fight to keep the timing. replace the timing belt. the codes po300,po302.po303 are for a rarandom misfire. when was the last tune up. change the sparks plugs

No this does not affect the fuel pump. It will affect the spark though. Hit the gas tank in the center a few times. If it starts then replace the fuel pump. Unfortunetly pumps with a few yaers on them will die when ran out of gas. If it doesn't start pull one of the spark plug wires, insert a screwdriver and put it close to the engine. crank the engine and watch for a spark. if there is no spark then replace the crank shaft sensor. before you replace the fuel pump.

Hi, the crank sensor is located behind the timing belt cover. It is right above the crank shaft timing gear.

you got to scan for codes first ,crank the engine first ,don"t put key in off position (that may erase CPS sensor codes )and scan it first.

IF THE CRANK SENSER HAS FAILED THE THE CAR WANT START AT ALL.Get a diagnosic check done at your local garage to find the problem.Good luck.

We replaced the crank sensor and another sensor still nothing.
