Where is the cam shaft position sensor on a 2001 Kia Sportage

TPS voltage is Close to 0 volts, normally the minimum, and 5 volts is typically the maximum. As an example, when a car's computer reads 2.5 volts from the TPS, it may mean the throttle is opened by 50% (your foot is pushing the pedal half-way down), and yes has a cam sensor its in between the cams behind the cam cover.

This is a common problem with KIA motors.

Need a little more info: Is it a V-6? Does it just die at random times? Kia has had problems with crank shaft position sensors. The vehicle will just die and may restart immediately or take several minutes till it will restart.

Typically no, the cam positioning sensor typically reads a marking of sorts on the end of the cam, telling the computer the proper position of the cam shaft.

check ATF level

The cam shaft position sensor is located right behind the exhaust cam by the fire wall. It is held by two 10 mm bolts, one on each side of the sensor. If you got the hood up and looking at the engine the cam that is on the right hand is the exhaust cam. To get to the CPS you have to remove the intake and cam top cover.

The speed sensors are a single pole, variable reluctance sensor, mounted to the rear axle housing and both front half shafts.

A toothed tone ring is press fit to the differential carrier next to the drive gear and provides the signal for the rear sensor.

The front tone rings are press fit to the half shaft assemblies

assuming the instrument cluster is ok check the output shaft sensor on the transmission. It sends the signal for speed of output shaft which is translated into mph.

The cam shaft position sensor is located right behind the exhost cam by the fire wall. It is held by two 10 mm bolts, one on each side of the sensor. If you got the hood up and looking at the engine the cam that is on the right hand is the exhost cam. To get to the CPS you have to remove the intake and cam top cover.

crankshaft sprocket up on timing mark, the exaust timing on the shield behind the timing gear. it will be E on the exaust cam gear and the I in the intake cam gear. then install belt.
