2019 Soul Nu 2.0L GDI
Pull Off Engine Cover
Release Rear of Cover
This automotive maintenance tutorial was specifically written to assist owners of the 2nd generation (2014, 2015, 2016, 2017, 2018 & 2019 model years) Kia Soul in checking or changing the two camshaft position sensors on the Nu 2.0 liter GDI inline four cylinder engine. (The procedure should be the same or very similar for the Gamma 1.6L GDI I4 engine or the Gamma 1.6L T-GDI turbocharged engine.)

Some of the symptoms of a failing or faulty camshaft position sensor include the following: rough idling, stalling, loss of power, reduced fuel economy (lower MPG), slow acceleration, difficulty starting, jerking, surging and a CEL / SES (check engine light / service engine soon) warning light on the dashboard.

Owners of other Kia, Hyundai or Genesis vehicles such as the Niro, Sportage, Sedona, Telluride, Sorento, Rio, Forte, Optima, K900, Cadenza, Stinger, Tucson, Santa Fe, Kona, Palisade, Elantra, Sonata, Accent, Veloster, Ioniq, Nexo, Venue, G70, G80 and G90 may also find these DIY instructions to be helpful.

The OEM (original equipment manufacturer) Kia / Hyundai camshaft position sensor part number is 39350-2E200.

The tools needed to complete this procedure include a 10mm socket with a 1/4" drive ratchet.

The first two steps are to open the hood and pull off the black plastic engine cover.

There are four rubber friction fasteners on the underside of the cover. Gently pull up the front edge to release the front two fasteners and then lift the rear edge to release the two other fasteners.


Engine Cover Removed
Top of Engine Exposed
Right (Driver) Side
Set the plastic cover aside in a safe place.

The two camshaft position sensors are located on the top right (driver) side of the engine.

They are close to the 12V automotive battery and the brake fluid reservoir.

Rear Camshaft Sensor
Front Camshaft Sensor
Two Camshaft Sensors
For this guide, I'll be replacing the front sensor located closer to the front bumper of the car.

In Picture # 9 in the row above, I'm pointing to the two camshaft sensors on the top of the engine.

Replacing Front Sensor
Push In Release Tab
Power Plug Removed
Push down the release tab on the grey plastic electrical connector before sliding it straight off the base of the old camshaft position sensor.
Loosen Counterclockwise
Set Aside Bolt
Sensor Bolt Removed
Loosen the bolt on the top of the sensor by turning it in the counterclockwise direction with a 10mm socket and a 1/4" drive ratchet.

Set the bolt aside in a safe place.

Gently loosen the old sensor by rotating it back and forth a few times to make sure it isn't stuck or "frozen" in the top of the engine.


Pull Out Old Sensor
Inspect Old Sensor
OEM # 39350-2E200
Inspect all sides of the old sensor for any damage or oily sludge.

The OEM sensor part number in this 2019 Soul was Hyundai / Kia 39350-2E200.

Empty Sensor Port
Lower In New Sensor
Spin In Bolt By Hand
Make sure that the red rubber o-ring gasket from the old sensor is not still attached to the engine.

Lower the new sensor into the port.

Line up the bolt hole in the sensor with the corresponding bolt hole in the top of the engine.

Spin in the silver metal bolt a few turns by hand in the clockwise direction to help prevent it from becoming cross threaded.

Tighten Bolt Clockwise
Electrical Connector
Power Plug Replaced
Tighten the bolt in the clockwise direction with the 10mm socket and a 1/4" drive ratchet until it is snug.

Try to avoid over tightening the bolt to prevent from cracking the plastic sensor housing.

Slide the power plug straight on to the base of the new sensor.

You should hear or feel the electrical connector "click" securely into place.

Lower Engine Cover
Push To Secure Fasteners
Camshaft Sensor Replaced
Line up the four rubber friction fasteners on the underside of the plastic cover with the four metal pegs on the top of the engine.

Firmly push down on the cover to secure the four fasteners.

If you have an OBDII scanner (also known as an OBD2 scan tool), check for any camshaft position sensor related DTC (diagnostic trouble codes) such as P0340, P0341, P0342, P0343 and P0344.

Clear the error codes with the OBDII scanner, turn off the ignition and then start the engine. If the new sensor was the cause of your engine's problem, the SES / CEL (service engine soon / check engine light) should stay off.

Be sure to write down the sensor change in your vehicle's service records.
