Need to change crankshaft position sensor for 2001 elantra

DTC P0054 for HO2S bank 1 sensor 2
DTC P0141 for HO2S bank 1 sensor 2
DTC P0335 Crankshaft Position (CKP) Sensor Circuit

P0335 = Crankshaft position (CKP) sensor - circuit malfunction.
There is an issue with the Crankshaft position sensor or the wiring to it. Get a Good Auto electrician to test the circuit and see how much it will cost to change the actual sensor.

code po335 refers to crankshaft position sensor(CKP)--circuit malfunction===causes wiring--CKP sensor --ECM
check the air gap and rotor security . Check for dirt in the air gap. Change CKP sensor.
code po113 refers to intake air temperature (IAT) sensor ---circuit malfunction===causes ---wiring open circuit /short circuit to positive ---wiring short to ground---ground wire defective--IAT sensor ---ECM

Error Code: P0335
Description:
Crankshaft Position (CKP) Sensor - Circuit Malfunction
Possible Cause:
Wiring.
Crankshaft position (CKP) sensor.
Engine control module (ECM).

DTC P0335 - Crankshaft Position Sensor A Circuit Malfunction
The crankshaft position sensor (CKP) measures crankshaft location and relays this information to the PCM (Powertrain Control Module). Depending on the vehicle, the PCM uses this crankshaft position information to time the spark properly or on some systems it is only for misfire detection and does not control spark timing. The CKP sensor is stationary and works in harmony with a reluctor ring (or toothed ring) that is attached to the crankshaft. As this reluctor ring passes in front of the CKP sensor, the magnetic field created by the CKP sensor is interrupted and this creates a square wave voltage signal that the PCM interprets as crankshaft position. If the PCM detects that there are no crankshaft pulses or if it sees a problem with the pulses on the output circuit, P0335 will set.

A P0335 "check engine light" code could be caused by:
Damaged CKP sensor connector
Damaged reluctor ring (missing teeth or not turning due to sheared-off keyway)
Sensor output open
Sensor output shorted to ground
Sensor output shorted to voltage
Failed crank sensor
Broken timing belt
Failed PCM

Did you do a crank relearn ? Could be a wiring issue , control module problem etc... Testing electrical circuit first , video's on youtube , all you would need is a DVOM - digital volt ohm meter . P0335 Kia Crankshaft Position Sensor Circuit c Replacing Crankshaft Position Sensor Code P0335

Make sure your crankshaft sensor is plugged in or replace the sensor if the plug is good.

Diagnostic Trouble Code (DTC) P0335

Magnetic Crankshaft Position Sensor Electrical Error

In this circuit DTC (data trouble code) sets when

a) The magnetic crankshaft position sensor is > 0.2V.

Or when

b) The minimum value of magnetic crankshaft position sensor is

Or when

c) The maximum value of magnetic crankshaft position sensor is higher than 2.2V.

could be ??the windings in the sensor have the insulation on the way out

QUESTION: Has anyone VERIFIED it's the Crank Sensor? Does the Check Engine light come ON when this happens? Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there.
If you find P0335 - Crankshaft position sensor circuit malfunction, then I'd say they are correct (after you eliminate wiring/connections as the cause).
